		<description><![CDATA[<p></p><p>Wondering about HP&#8217;s counter for 3Par. Dell&#8217;s offer makes sense: they&#8217;re building expertise and a high-margin business. Dell and long time supplier EMC are growing apart as Dell realizes that that the relationship is doing little for them &#8211; and a lot for EMC.</p>
<p>But HP? OK, they may want a replacement for their high-end Hitachi boxes. They might be thinking that 3Par&#8217;s architecture will be a useful bridge to its scale-out architecture offerings from IBRIX and Lefthand. Maybe they see a major opportunity in storage for their industry-leading blade servers.</p>
<p>But a $1.6B bridge? </p>
<p>3Par&#8217;s growth hit a wall this last year compared to the rapid growth of &#8217;08 to &#8217;09 &#8211; reaching $194 million for the year ended March 31. They also lost money due to some non-cash expenses such as stock-based compensation. Not bad considering the times, but not what Data Domain was doing either.</p>
<p><strong>New product purgatory</strong><br />
Let&#8217;s say HP can take 3Par&#8217;s gross margins to 60% after the obligatory year in HP&#8217;s integration purgatory. Code reviews, testing and integration, part numbering, pricing, sales and service training. Figure 9-12 months before they start selling in earnest.</p>
<p>In the meantime 3Par sales and margins plunge. HDS customers go into fight-or-flight mode &#8211; and HDS sales rise. EMC and other competitor reps go into overdrive to unhook HP&#8217;s storage business. Company bloggers spread rumors, half-truths, maybe even truths.</p>
<p>All good fun. But how does HP monetize this massive acquisition? </p>
<p><strong>The StorageMojo take</strong><br />
They have to grow the business. My back of the envelope SWAG is they have to grow it to over $1.5B in 3-5 years, assuming overall profitability similar to EMC&#8217;s last full fiscal year.</p>
<p>That&#8217;s 7x growth. Not impossible, but not easy either. HP&#8217;s sales force already has a lot on its plate.</p>
<p>The bigger issue: the high-end block storage business isn&#8217;t growing. It is one thing to grow in a growing market &#8211; much harder in a static or shrinking market. Customers already have vendor relationships and don&#8217;t see the shrinking market as strategic. </p>
<p>Yes, EMC, the bell weather of high-end block storage, is showing growth. But looking at the numbers it isn&#8217;t the base product that is driving the growth, but add-on like V-Max and new products like Data Domain.</p>
<p>The high-end block business is stalled, probably permanently. Partly that is due to the recession, but it also reflects the secular trend away from block, despite virtualization&#8217;s positive impact on block demand. </p>
<p>Thus HP &#8211; Donatelli, really &#8211; is placing a big bet on a slowing market. If HP/3Par can take a chunk out of EMC&#8217;s business, it may pay off. But it won&#8217;t be easy or quick.</p>
<p><strong>Update:</strong> Dell updated their bid to slightly above HP&#8217;s, a strong signal they won&#8217;t go much higher. Expect HP to counter and close the deal. <strong>End update.</strong></p>

		<description><![CDATA[<p></p><p>I&#8217;m in Silicon Valley at the Flash Memory Summit. The big news so far: Intel and Micron announced they are sampling an 8 GB, 3 bit-per-cell (3bpc) NAND flash. </p>
<p>Commercial availability is expected in Q4, but don&#8217;t be surprised if that date slips. Process tweaks needed to reach full spec parts in the next 6 months aren&#8217;t guaranteed.</p>
<p><strong>Bang/$</strong><br />
3bpc means 50% more capacity per $. That&#8217;s good. </p>
<p>The tradeoff: it will only handle about 1,000 writes before failing. Which, as I pointed out <a href="http://storagemojo.com/2006/10/19/ram-based-ssds-are-toast-yippie-ki-yay/" target="_blank">4 years ago</a> in an early post about server flash SSDs, isn&#8217;t much of a problem when you have lots of capacity.</p>
<p>This flash will 1st go into products like USB thumb drives or SD cards, where you won&#8217;t write to it 1,000 times anyway. With wear-leveling you&#8217;ll have to write 8,000,000 MB of data to an 8 GB part before it croaks. That is 2 million 4 MB JPEGs. That&#8217;s a lot of snapshots.</p>
<p>Since most of these will go into devices that hold 16, 32 or even 64 GB of flash, multiply 2 million by 2, 4 or 8 and it is obvious that casual users will never wear out 3bpc flash.</p>
<p>Write performance will suffer as well, but how much remains to be seen. The effect will depend on how many flash chips are on the device: flash controllers write data in parallel, so the more chips the faster the write. </p>
<p><strong>The StorageMojo take</strong><br />
3bpc products will have a ripple effect on other flash parts. Price sensitive products &#8211; most flash parts &#8211; will want to move to 3bpc ASAP, but the volumes won&#8217;t be there. But as production ramps, 2bpc flash will face big price pressure as vendors with older fabs try to keep them running.</p>
<p>Translation: expect that flash prices will resume their downward path after 3 quarters of flat prices. Yay!</p>
<p><strong>Comments welcome, of course.</strong> SSD vendors shipped about 10 million SSDs in the last 12 months. Sounds good, but tiny compared to over 500 million hard drives.</p>

<p>Flash&#8217;s impact on architecture is entering a new phase. On the consumer side shipping 3-bit MLC will drive cost down and adoption up. That&#8217;s the volume side of the market that keeps multi-billion dollar fabs busy. And a headache for drive vendors.</p>
<p>On the system side the quick-easy-cheap SSD swap-ins are joined by products that capitalize on flash benefits at a deeper level. A little non-volatility can go a long way in making current products faster-better-cheaper.</p>

<p>It looks like flash prices have started declining again. Good news for broader adoption, especially on the consumer side. 3-bit MLC will accelerate that. </p>
<p>Hope to see greater advantage taken of increasing flash storage capacities: as capacities increase the importance of write-cycles declines. I&#8217;ll be looking for other creative takes on flash today.</p>

		<description><![CDATA[<p></p><p>Concall today with Bryan Cantrill, the smart guy behind <a href="http://en.wikipedia.org/wiki/DTrace" target="_blank">Dtrace</a>. Dtrace was the engine behind <strike>Sun&#8217;s</strike> Oracle&#8217;s Fishworks server and application monitor. Dtrace has also been incorporated into OS X.</p>
<p>Bryan left Oracle last week and started Monday at <a href="http://www.joyent.com/" target="_blank">Joyent</a> the cloud infrastructure provider, as VP of engineering. Why?</p>
<p>Bryan is an instrumentation geek. He really wants to know what&#8217;s going on. Instrumentation in the cloud is the next big challenge.</p>
<p>That makes sense: there are so many moving parts that understanding and resolving performance and availability issues will be critical to the widespread adoption of cloud. </p>
<p><strong>Tech epiphanies</strong><br />
Bryan described 3 technology epiphanies that he&#8217;s enjoyed. The 1st was when he saw Java for the first time back in 1995. The 2nd was when he saw a Ruby on Rails video about deploying a web app.</p>
<p>His 3rd epiphany came recently when he saw something called node.js. Developed by Ryan Dahl it turns the JavaScript paradigm on its head: node.js runs on the server, not the client.</p>
<p><strong>Latency bubbles</strong><br />
We know that server I/O latency can kill performance. It&#8217;s even worse in the cloud.</p>
<p>A single bad drive can hose a server if the app is holding locks. What if you have a webpage that relies on five different Web services, or as many Amazon pages do, 150 services?</p>
<p>You need an infrastructure that is resilient in the face of long latency while maintaining high throughput. Bryan says that most failures are not hard failures but are latency bubbles that cascade out and lock up the rest of the infrastructure.</p>
<p>Ryan took Google&#8217;s of V8 JavaScript engine and extended it so you can handle long latency events. Without locking up the server.</p>
<p>Ryan does a fine job <a href="http://www.youtube.com/watch?v=F6k8lTrAE2g" target="_blank">introducing node.js</a> in a 1 hour Google Tech Talk last week. He outlined how to build a server that can handle 10,000 or more users. His goal with node.js was to make it easy to write high-performance servers.</p>
<p><a href="http://storagemojo.com/wp-content/uploads//2010/08/nodejs_architecture1.jpg"><img src="http://storagemojo.com/wp-content/uploads//2010/08/nodejs_architecture1.jpg" alt="" title="nodejs_architecture" width="470" height="404" class="aligncenter size-full wp-image-2113" /></a></p>
<p>There is an arms race out there for performance – Google, Apple, Mozilla, Opera, Microsoft – to win the hearts and eyeballs of hundreds of millions of consumers. Fickle consumers.</p>
<p>Node.js only exposes nonblocking asynchronous interfaces to the programmer. It has very few abstractions. Its power lies in the fact that it moves you away from certain interfaces like synchronous I/O that you shouldn&#8217;t do.</p>
<p>You don&#8217;t have to worry about some event completing and taking over while you&#8217;re in the middle of something else. Each node.js is a single thread. If you want to do more work you start multiple node.js instances and let the kernel do the load balancing.</p>
<p>Memory isolation is enforced at the process boundary. The kernel manages it, not the coder. That&#8217;s a good thing.</p>
<p><strong>The StorageMojo take</strong><br />
Latency is the app killer of the cloud. The current cloud focus on write once/read never apps reflects that.</p>
<p>The fight against latency proceeds on many fronts: storage; network; CPU; and software. <a href="http://www.asankya.com/" target="_blank">Asankya</a> and others have good ideas for reducing Internet latency. Flash architectures are undergoing rapid evolution. Multicore and multiprocessor servers are attacking throughput.</p>
<p>Node.js is a big step in the right direction. Removing the dependency is that synchronous I/O create means any more resilient and higher performance infrastructure. Ryan reports that a Japanese website is already running several hundred thousand users on node.js instances.</p>
<p>As for Bryan, he&#8217;ll bring the same intelligence and energy to Joyent that he brought to Dtrace and Fishworks. Expect more great things.</p>
<p><strong>Courteous comments welcome, of course.</strong> <strong>Update:</strong> The other smart guys behind Dtrace are the redoubtable <a href="http://blogs.sun.com/ahl/category/DTrace" target="_blank"> Adam Leventhal</a>and Mike Shapiro.</p>

		<description><![CDATA[<p></p><p>This came in over the transom from a semiconductor engineer. He&#8217;s wants home archive storage and is wondering why no one seems to sell it. I&#8217;ve been grappling with the same issue. </p>
<p>Here&#8217;s an edited-for-length excerpt from his letter:</p>
<blockquote><p>
I use RAID server products from Netgear and QNAP and have been searching for my ideal server product. I don&#8217;t understand why it doesn&#8217;t exist. My hunt is for a server with integrated error checking to ensure that bit errors can be caught and rectified.  My goal is a system that secures the integrity of the files stored upon it. As far as I am aware this kind of functionality does not exist and isn&#8217;t discussed anywhere.  </p>
<p>For example, once I have a video file (which can be the result of many hours of editing) it isn&#8217;t subsequently modified, just read on occasion as required. I don&#8217;t want any bit errors on this file &#8211; every change is just a corruption. I backup my files, I just want to make sure that what I am backing up is the same as when it was first written. </p>
<p>I don&#8217;t want to run a piece of software over the network, I want the server to run a check and fix any errors that it finds. It is something that I would gladly pay a premium for. I think there is a market for this as there must be a lot of users who have files that never change.</p>
<p>Frustrated in California
</p></blockquote>
<p><strong>Dear Frustrated</strong><br />
You&#8217;ve identified the key problem: RAID systems aren&#8217;t for archives. RAID keeps your data available after a disk failure &#8211; sometimes 2 disk failures &#8211; but they do not ensure long-term data integrity. Or even short-term integrity. Not their thing.</p>
<p>This is what archives &#8211; traditionally tape &#8211; are for.</p>
<p>But tape is a tough sell to the home &#038; SOHO market. Low-end drives &#8211; DAT, SVR, VXA &#8211; cost several hundred dollars plus the tapes. DLT/LTO drives start around $1200 with $40 tapes.</p>
<p>You can buy an external Blu-ray burner for those prices and 50 GB media for a few bucks each. On sale BR media is starting to reach the 5¢/GB level of 2 TB drives, and the longevity should be better.</p>
<p>But I have over 500 GB of video alone. Shuffling 10 or more BR media &#8211; 20 if I&#8217;m paranoid &#8211; reminds me of floppy backups. Yuck.</p>
<p><strong>The current plan:</strong></p>
<ol>
<li>Create zip archives of files and folders I want to preserve.</li>
<li>Back them up to 2 local hard drives.</li>
<li>And ship them off to my online backup provider.</li>
</ol>
<p>What I don&#8217;t know is how robust zip archives are. There is a 32-bit CRC, but what does that do for a 10 GB folder of PDFs?</p>
<p>Also, I wonder about the advisability of zipping compressed formats such video and audio files. It might be worth the computational overhead and the possible larger files <i>if</i> the zip file is robust.</p>
<p><strong>The StorageMojo take</strong><br />
Frustrated isn&#8217;t the first home user to want an archive and he won&#8217;t be the last. Hundreds of millions of home users will see the need over the next decade. </p>
<p>The question is whether or not someone can design a commercially viable system for home and SOHO use. It is obvious that drive vendors have the cost advantage, especially with the advent of easy and cheap USB drive docks, if they build a disk drive designed for that purpose. </p>
<p>An archive drive can be slower &#8211; 4200 or even 3600 RPM &#8211; and less dense. Optimized for large transfers. Slower, cheaper actuators and drive electronics. </p>
<p>Single platter 2.5&#8243; 7mm drives could be the sweet spot: minimal head cost; slim cartridge-like form factor; and much faster than optical. Then it is just a matter of getting the volumes up and the costs down.</p>
<p>But that&#8217;s just one idea. Please comment on how you would solve the home and SOHO archive problem.</p>

			<content:encoded><![CDATA[<p></p><p>This came in over the transom from a semiconductor engineer. He&#8217;s wants home archive storage and is wondering why no one seems to sell it. I&#8217;ve been grappling with the same issue. </p>
<p>Here&#8217;s an edited-for-length excerpt from his letter:</p>
<blockquote><p>
I use RAID server products from Netgear and QNAP and have been searching for my ideal server product. I don&#8217;t understand why it doesn&#8217;t exist. My hunt is for a server with integrated error checking to ensure that bit errors can be caught and rectified.  My goal is a system that secures the integrity of the files stored upon it. As far as I am aware this kind of functionality does not exist and isn&#8217;t discussed anywhere.  </p>
<p>For example, once I have a video file (which can be the result of many hours of editing) it isn&#8217;t subsequently modified, just read on occasion as required. I don&#8217;t want any bit errors on this file &#8211; every change is just a corruption. I backup my files, I just want to make sure that what I am backing up is the same as when it was first written. </p>
<p>I don&#8217;t want to run a piece of software over the network, I want the server to run a check and fix any errors that it finds. It is something that I would gladly pay a premium for. I think there is a market for this as there must be a lot of users who have files that never change.</p>
<p>Frustrated in California
</p></blockquote>
<p><strong>Dear Frustrated</strong><br />
You&#8217;ve identified the key problem: RAID systems aren&#8217;t for archives. RAID keeps your data available after a disk failure &#8211; sometimes 2 disk failures &#8211; but they do not ensure long-term data integrity. Or even short-term integrity. Not their thing.</p>
<p>This is what archives &#8211; traditionally tape &#8211; are for.</p>
<p>But tape is a tough sell to the home &#038; SOHO market. Low-end drives &#8211; DAT, SVR, VXA &#8211; cost several hundred dollars plus the tapes. DLT/LTO drives start around $1200 with $40 tapes.</p>
<p>You can buy an external Blu-ray burner for those prices and 50 GB media for a few bucks each. On sale BR media is starting to reach the 5¢/GB level of 2 TB drives, and the longevity should be better.</p>
<p>But I have over 500 GB of video alone. Shuffling 10 or more BR media &#8211; 20 if I&#8217;m paranoid &#8211; reminds me of floppy backups. Yuck.</p>
<p><strong>The current plan:</strong></p>
<ol>
<li>Create zip archives of files and folders I want to preserve.</li>
<li>Back them up to 2 local hard drives.</li>
<li>And ship them off to my online backup provider.</li>
</ol>
<p>What I don&#8217;t know is how robust zip archives are. There is a 32-bit CRC, but what does that do for a 10 GB folder of PDFs?</p>
<p>Also, I wonder about the advisability of zipping compressed formats such video and audio files. It might be worth the computational overhead and the possible larger files <i>if</i> the zip file is robust.</p>
<p><strong>The StorageMojo take</strong><br />
Frustrated isn&#8217;t the first home user to want an archive and he won&#8217;t be the last. Hundreds of millions of home users will see the need over the next decade. </p>
<p>The question is whether or not someone can design a commercially viable system for home and SOHO use. It is obvious that drive vendors have the cost advantage, especially with the advent of easy and cheap USB drive docks, if they build a disk drive designed for that purpose. </p>
<p>An archive drive can be slower &#8211; 4200 or even 3600 RPM &#8211; and less dense. Optimized for large transfers. Slower, cheaper actuators and drive electronics. </p>
<p>Single platter 2.5&#8243; 7mm drives could be the sweet spot: minimal head cost; slim cartridge-like form factor; and much faster than optical. Then it is just a matter of getting the volumes up and the costs down.</p>
<p>But that&#8217;s just one idea. Please comment on how you would solve the home and SOHO archive problem.</p>

		<description><![CDATA[<p></p><p>A commenter recently asked</p>
<blockquote><p>
Archivas was focused on archive, do you expect the new solution to sustain performance for primary storage as well?
</p></blockquote>
<p>Which is a good question, if you know what &#8220;primary&#8221; means. Do we?</p>
<p><strong>Tiers of a clown</strong><br />
10 years ago we all agreed on 1st tier or primary storage: block-based; RAID 5; enterprise FC or SCSI drives; SCSI, FC or ESCON host connects; optimized for transactional workloads; and large mirrored (with 1 notable exception) caches. When SANS took off we stuck FC switches in front of the boxes and called it good.</p>
<p>But something happened to that consensus: iSCSI; NFS; CIFS; SSD; MEMcache; Internet scale-out; Infiniband; 10GigE; storage &#038; processor virtualization; CDNs; web-serving; pNFS; and lower-cost out-sourced high-scale infrastructure (i.e. cloud). And more &#8211; such as non-SQL data management &#8211; is coming.</p>
<p><strong>Will the real primary storage please stand up?</strong><br />
Amazon runs a high-growth $25B/yr business on scale-out storage, servicing millions of customers, taking real money and shipping real goods, 7x24x365. Smells like enterprise spirit.</p>
<p>Is Amazon&#8217;s storage &#8220;primary&#8221; and, if so, what makes it primary?</p>
<p>Yes, it is primary storage. No, it isn&#8217;t the logo that makes it so. </p>
<p><strong>Workload &#038; service level</strong><br />
It&#8217;s tempting to consider workload, but what workload? IOPS? Bandwidth? </p>
<p>How about parallelism? Web service is highly parallel. ACID database updates less so. </p>
<p>And what about files vs blocks? Blocks don&#8217;t require as much processing as files, as the host is handling the file system. </p>
<p>It is <a href="http://storagemojo.com/2008/09/09/our-changing-file-workloads/" target="_blank">clear</a> that most files aren&#8217;t often accessed. Does primary storage for files mean availability and reasonable performance? Or is there little difference between archive and primary for files?</p>
<p>NetApp is deduping primary storage. Others will follow, whether it makes sense or not, at least in messaging. Skeptics ask &#8220;If it is deduped, is it really primary?&#8221;</p>
<p><strong>The StorageMojo take</strong><br />
We do a disservice to customers if we talk about &#8220;primary&#8221; storage as a class of equipment. It isn&#8217;t. </p>
<p>Primary storage is whatever works as primary storage for your application. Bare SATA drives Velcro&#8217;d to motherboards to a big cluster of DMXs. Both are in use in major enterprises for mission critical applications &#8211; and they both work.</p>
<p>The 60 year secular trend to cooler data is the cause &#8211; an inverse of Moore&#8217;s Law. As the average accesses of data declines, technologies that meet the need at a lower cost become attractive, find a market, and grow. Niche products become mainstream &#8211; and perhaps &#8220;primary&#8221; &#8211; for their markets.</p>
<p>At the same time Moore&#8217;s Law is working its magic: creaky slow 10Mbit Ethernet becomes 10GigE. Board level controllers become chips. Storage software migrates from firmware to a stack running on commodity processors. Yesterday&#8217;s &#8220;archive&#8221; storage is tomorrows &#8220;primary&#8221; storage for the right apps.</p>
<p>Even the term &#8220;enterprise&#8221; is losing its meaning. As firms begin the 10 year migration to  private clouds for cooler data, commodity hardware &#8211; servers, unmanaged switches, SATA drives &#8211; will be knit by cluster software that may even be open source. It is &#8220;enterprise&#8221; because an enterprise is using it.</p>
<p>This why all the big iron vendors are migrating their software from embedded firmware to stacks running on commodity processors and operating systems. For the mainstream market the commodities are fast enough and the economics are compelling.</p>
<p>If if works for you, it&#8217;s primary.</p>
<p><strong>Courteous comments welcome, of course.</strong> BTW, I&#8217;m getting a briefing from HDS on the old Archivas product, so maybe I&#8217;ll have more to say RSN.</p>

<p>The practitioners in the group &#8211; one who loves XIV, others with EMC and NetApp kit &#8211; were surprised by what the HDS stuff does. Such as virtualizing and managing your current storage platforms, regardless of vendor. </p>
<p>Seems like the big guys have been promising that for years. HDS delivered? Whoa.</p>
<p>A couple of things impressed me:</p>
<ul>
<li>The senior Japanese execs weren&#8217;t the starchy, face-saving guys I&#8217;d expected. The Chairman of Hitachi made a speech to about 10,000 people without a tie, and all the other execs I spoke to followed suit. Even giving careful non-answers they came across as relaxed and realistic. Are they also decisive? We&#8217;ll see.  </li>
<li>HDS has a clustered object store. I hope to get briefed on it next month.</li>
<li>The parent company has a vision for using massive amounts of data to improve our quality of life. Since they also produce power systems and high-speed trains they have a direct line into some critical issues.</li>
</ul>
<p><strong>The StorageMojo take</strong><br />
HDS is a multi-billion dollar company with some leading edge products and technologies. They&#8217;re about the size of NetApp &#8211; and I know you&#8217;ve heard of them.</p>
<p>As their OEM relationship with Sun winds down &#8211; or at least I expect it to &#8211; they&#8217;ll have more direct contact with a new group of customers. Now is the time for HDS to sharpen their messaging and turn up the volume. </p>
<p>Sadly that isn&#8217;t likely. The internal dynamics of the company seem to lead to generic messaging that fails to plant a hook. Maybe it is a consensus thing. But they aren&#8217;t doing customers any favors.</p>

		<description><![CDATA[<p></p><p>Cloud computing gets a bad rap because it can&#8217;t replace corporate data centers for mission critical apps. But new computing paradigms never do that: it is the new capabilities they enable that drive adoption. Case in point: transcoding.</p>
<p><strong>Why?</strong><br />
Anyone who shoots video soon discovers that changing from, say, AVCHD to an editing-friendly codec and then to H.264 for distribution takes a lot of compute cycles. Conversion from one codec to another is called <i>transcoding</i>. It is the price we pay for high quality compressed content. </p>
<p>Compression and format conversion are necessary because highly compressed video &#8211; the kind most camcorders shoot &#8211; isn&#8217;t easy to edit. And the stuff that&#8217;s easy to edit has large files that chew up bandwidth and storage.</p>
<p>So we transcode. Add to that the number of formats we use &#8211; ranging from iPhones to flash to SD and 1080p &#8211; and transcoding is a major CPU cycle sink.</p>
<p>Fortunately, transcoding can be a highly parallel operation. A frame &#8211; or a series of frames &#8211; can be divided and split among multiple cores and CPUs.</p>
<p><strong>Where?</strong><br />
Where can you find a lot of CPUs for a quick job? Right, the cloud. Which is why there are a number of online services that front-end Amazon Web Services to provide transcoding.</p>
<p>I spoke to the CEO of startup <a href="http://zencoder.com/" target="_blank">Zencoder</a>, Jon Dahl to learn more.</p>
<p><strong>Zencoder</strong><br />
Zencoder is a transcoding service provider that uses Amazon as a cloud provider. The Zencoder team has developed transcoding infrastructure for several startups and finally decided to build a general-purpose service.</p>
<p>While they use open source software in their stack &#8211; as do most transcoding providers &#8211; their major value-add is in a high-performance scalable interface. Handling 100,000 concurrent transcodes is non-trivial.</p>
<p>They also look out for problems common in transcoding such as audio/video getting out of sync and aspect ratio distortion. They can transcode 1080p faster than real time. And they&#8217;ve licensed the proprietary formats as well.</p>
<p>Amazon offers Linux as a service and a file service. S3&#8242;s files are limited to 5 GB, but that isn&#8217;t a problem for Zencoder: customers can specify input and output locations, bypassing Amazon storage.</p>
<p>Also they don&#8217;t transcode Mac ProRes &#8211; Final Cut Pro&#8217;s preferred editing format &#8211; today. But they do handle QuickTime movies. </p>
<p><strong>The StorageMojo take</strong><br />
So the glass house doesn&#8217;t want to outsource cloud infrastructure. Who cares? They&#8217;re the last to adopt new technology anyway.</p>
<p>It is apps like transcoding that drive the business. In 5 years much, perhaps most, transcoding will be cloud-based.</p>
<p>Before the digital video craze in the last 5 years there wasn&#8217;t much demand for transcoding. But today, with HD video smartphones, millions are producing videos that they want to share and save.</p>
<p>Your smartphone won&#8217;t have the cycles to do it, but the cloud does. Expect transcoding vendors to add new features, such as noise-reduction or sharpening.</p>
<p>Business units are discovering the power of short videos to inform, train, persuade and excite. All at a fraction of the cost of 4-color brochures.</p>
<p>The outlook for storage vendors is mixed. Yes, much more storage will be sold &#8211; but cost-conscious cloud managers will be buying it. And as more new services develop on the cloud, consumers will be as hazy about &#8220;local&#8221; and &#8220;cloud&#8221; as they are about &#8220;memory&#8221; and &#8220;disk&#8221; today. Branding nightmare, but that&#8217;s where those petabytes will be.</p>

		<description><![CDATA[<p></p><p>Given how hard it is to save data you <i>want</i> (see <a href="http://www.zdnet.com/blog/storage/the-universe-hates-your-data/975" target="_blank">The Universe hates your data</a>) to keep, losing data on the web should be easy. It isn&#8217;t, because it gets stored so many places in its travels.</p>
<p><strong>Problem</strong><br />
But the power of the web means that silliness can now be stored and found with the speed of a Google search. You don&#8217;t want sexy love notes &#8211; or pictures &#8211; to a former flame posted after infatuation ends. </p>
<p>Or maybe you want to discuss relationship, health or work problems with a friend over email &#8211; and don&#8217;t want your musings to be later shared with others. Wouldn&#8217;t it be nice to know that such messages will become unreadable even if your friend is unreliable?</p>
<p>Researchers built a prototype service &#8211; Vanish &#8211; that seeks to:</p>
<blockquote><p>
. . . ensure that all copies of certain data become unreadable after a user-specified time, without any specific action on the part of a user, without needing to trust any single third party to perform the deletion, and even if an attacker obtains both a cached copy of that data and the user&#8217;s cryptographic keys and passwords.
</p></blockquote>
<p>That&#8217;s a tall order. Their 1st proof-of-concept failed. But they are continuing the fight.</p>
<p><strong>Vanish</strong><br />
In <a href="http://vanish.cs.washington.edu/pubs/usenixsec09-geambasu.pdf" target="_blank">Vanish: Increasing Data Privacy with Self-Destructing Data</a> Roxana Geambasu, Tadayoshi Kohno, Amit A. Levy and Henry M. Levy of the University of Washington computer science department present an architecture and a prototype to do just that.</p>
<p>Ironically, the project utilizes the same P2P infrastructures that preserves and distribute data: BitTorrent&#8217;s VUZE distributed hash table (DHT) client. </p>
<p>The basic idea is this: Vanish encrypts your data with a random key, destroys the key, and then sprinkles pieces of the key across random nodes of the DHT. You tell the system when to destroy the key and your data goes <i>poof!</i> </p>
<p>They developed a data structure called a <i>Vanishing Data Object</i> (VDO) that encapsulates user data and prevents the content from persisting. And the data becomes unreadable even if the attacker gets a pristine copy of the VDO from before its expiration and all the associated keys and passwords.</p>
<p>Here&#8217;s a timeline for that attack:</p>
<p><a href="http://storagemojo.com/wp-content/uploads//2010/07/vdo_usage_and_attack.jpg"><img src="http://storagemojo.com/wp-content/uploads//2010/07/vdo_usage_and_attack.jpg" alt="" title="vdo_usage_and_attack" width="475" height="208" class="aligncenter size-full wp-image-2083" /></a><br />
<strong>DHT overview</strong></p>
<blockquote><p>
A DHT is a distributed, peer-to-peer (P2P) storage network. . . . DHTs like Vuze generally exhibit a put/get interface for reading and storing data, which is implemented internally by three operations: <code>lookup, get</code>, and <code>store</code>. The data itself consists of an (<i>index, value</i>) pair. Each node in the DHT manages a part of an astronomically large index name space (e.g., 2<sup>160</sup> values for Vuze).
</p></blockquote>
<p>DHTs are available, scalable, broadly distributed and decentralized with rapid node churn. All these properties are ideal for an infrastructure that has to withstand a wide variety of attacks.</p>
<p><strong>Vanish architecture</strong><br />
<a href="http://storagemojo.com/wp-content/uploads//2010/07/vanish_system_architecture.jpg"><img src="http://storagemojo.com/wp-content/uploads//2010/07/vanish_system_architecture.jpg" alt="" title="vanish_system_architecture" width="462" height="220" class="aligncenter size-full wp-image-2082" /></a><br />
Data (D) is encrypted (E) with key (K) to deliver cyphertext (C). Then K is split into N shares &#8211; K<sub>1</sub>,&#8230;,K<sub>N</sub> &#8211; and distributed across the DHT using a random access key (L) and a secure pseudo-random number generator. The K split uses a redundant erasure code so that a user definable subset of N shares can reconstruct the key.</p>
<p>The erasure codes are needed because DHTs lose data due to node churn. It is a bug that is also a feature for secure destruction of data.</p>
<p><strong>Prototype</strong><br />
They built a Firefox plug-in for Gmail to create self-destructing emails and another &#8211; FireVanish &#8211; for making any text in a web input box self-destructing. They also built a file app, so you can make any file self-destructing. Handy for Word backup files that you don&#8217;t want to keep around.</p>
<p>The major change to the Vuze BitTorrent client was less than 50 lines of code to prevent <code>lookup</code> sniffing attacks. Those changes only affect the client, not the DHT.</p>
<p>The Vanish proto was <a href="http://z.cs.utexas.edu/users/osa/unvanish/" target="_blank">cracked</a> by a group of researchers at UT Austin, Princeton, and U of Michigan. They found that an eavesdropper could collect the key shards from the DHT and reassemble the &#8220;vanished&#8221; content.</p>
<p>Who is going to collect all the shard-like pieces on DHTs? Other than the NSA and other major intelligence services, probably no one. For extra security the data can be encrypted before VDO encapsulation.</p>
<p><strong>The StorageMojo take</strong><br />
The Internet is paid for with our loss of privacy. Young people may think it no great loss, check back in 20 years and we&#8217;ll see what you think then.</p>
<p>It is slowly dawning on the public that their lives are an open book on the Internet. Expect a growing market for private communication and storage if ease-of-use and trust issues can be resolved.</p>
<p>You don&#8217;t have to be Tiger Woods to want to keep your private life private. I hope the Vanish team succeeds.</p>

			<content:encoded><![CDATA[<p></p><p>Given how hard it is to save data you <i>want</i> (see <a href="http://www.zdnet.com/blog/storage/the-universe-hates-your-data/975" target="_blank">The Universe hates your data</a>) to keep, losing data on the web should be easy. It isn&#8217;t, because it gets stored so many places in its travels.</p>
<p><strong>Problem</strong><br />
But the power of the web means that silliness can now be stored and found with the speed of a Google search. You don&#8217;t want sexy love notes &#8211; or pictures &#8211; to a former flame posted after infatuation ends. </p>
<p>Or maybe you want to discuss relationship, health or work problems with a friend over email &#8211; and don&#8217;t want your musings to be later shared with others. Wouldn&#8217;t it be nice to know that such messages will become unreadable even if your friend is unreliable?</p>
<p>Researchers built a prototype service &#8211; Vanish &#8211; that seeks to:</p>
<blockquote><p>
. . . ensure that all copies of certain data become unreadable after a user-specified time, without any specific action on the part of a user, without needing to trust any single third party to perform the deletion, and even if an attacker obtains both a cached copy of that data and the user&#8217;s cryptographic keys and passwords.
</p></blockquote>
<p>That&#8217;s a tall order. Their 1st proof-of-concept failed. But they are continuing the fight.</p>
<p><strong>Vanish</strong><br />
In <a href="http://vanish.cs.washington.edu/pubs/usenixsec09-geambasu.pdf" target="_blank">Vanish: Increasing Data Privacy with Self-Destructing Data</a> Roxana Geambasu, Tadayoshi Kohno, Amit A. Levy and Henry M. Levy of the University of Washington computer science department present an architecture and a prototype to do just that.</p>
<p>Ironically, the project utilizes the same P2P infrastructures that preserves and distribute data: BitTorrent&#8217;s VUZE distributed hash table (DHT) client. </p>
<p>The basic idea is this: Vanish encrypts your data with a random key, destroys the key, and then sprinkles pieces of the key across random nodes of the DHT. You tell the system when to destroy the key and your data goes <i>poof!</i> </p>
<p>They developed a data structure called a <i>Vanishing Data Object</i> (VDO) that encapsulates user data and prevents the content from persisting. And the data becomes unreadable even if the attacker gets a pristine copy of the VDO from before its expiration and all the associated keys and passwords.</p>
<p>Here&#8217;s a timeline for that attack:</p>
<p><a href="http://storagemojo.com/wp-content/uploads//2010/07/vdo_usage_and_attack.jpg"><img src="http://storagemojo.com/wp-content/uploads//2010/07/vdo_usage_and_attack.jpg" alt="" title="vdo_usage_and_attack" width="475" height="208" class="aligncenter size-full wp-image-2083" /></a><br />
<strong>DHT overview</strong></p>
<blockquote><p>
A DHT is a distributed, peer-to-peer (P2P) storage network. . . . DHTs like Vuze generally exhibit a put/get interface for reading and storing data, which is implemented internally by three operations: <code>lookup, get</code>, and <code>store</code>. The data itself consists of an (<i>index, value</i>) pair. Each node in the DHT manages a part of an astronomically large index name space (e.g., 2<sup>160</sup> values for Vuze).
</p></blockquote>
<p>DHTs are available, scalable, broadly distributed and decentralized with rapid node churn. All these properties are ideal for an infrastructure that has to withstand a wide variety of attacks.</p>
<p><strong>Vanish architecture</strong><br />
<a href="http://storagemojo.com/wp-content/uploads//2010/07/vanish_system_architecture.jpg"><img src="http://storagemojo.com/wp-content/uploads//2010/07/vanish_system_architecture.jpg" alt="" title="vanish_system_architecture" width="462" height="220" class="aligncenter size-full wp-image-2082" /></a><br />
Data (D) is encrypted (E) with key (K) to deliver cyphertext (C). Then K is split into N shares &#8211; K<sub>1</sub>,&#8230;,K<sub>N</sub> &#8211; and distributed across the DHT using a random access key (L) and a secure pseudo-random number generator. The K split uses a redundant erasure code so that a user definable subset of N shares can reconstruct the key.</p>
<p>The erasure codes are needed because DHTs lose data due to node churn. It is a bug that is also a feature for secure destruction of data.</p>
<p><strong>Prototype</strong><br />
They built a Firefox plug-in for Gmail to create self-destructing emails and another &#8211; FireVanish &#8211; for making any text in a web input box self-destructing. They also built a file app, so you can make any file self-destructing. Handy for Word backup files that you don&#8217;t want to keep around.</p>
<p>The major change to the Vuze BitTorrent client was less than 50 lines of code to prevent <code>lookup</code> sniffing attacks. Those changes only affect the client, not the DHT.</p>
<p>The Vanish proto was <a href="http://z.cs.utexas.edu/users/osa/unvanish/" target="_blank">cracked</a> by a group of researchers at UT Austin, Princeton, and U of Michigan. They found that an eavesdropper could collect the key shards from the DHT and reassemble the &#8220;vanished&#8221; content.</p>
<p>Who is going to collect all the shard-like pieces on DHTs? Other than the NSA and other major intelligence services, probably no one. For extra security the data can be encrypted before VDO encapsulation.</p>
<p><strong>The StorageMojo take</strong><br />
The Internet is paid for with our loss of privacy. Young people may think it no great loss, check back in 20 years and we&#8217;ll see what you think then.</p>
<p>It is slowly dawning on the public that their lives are an open book on the Internet. Expect a growing market for private communication and storage if ease-of-use and trust issues can be resolved.</p>
<p>You don&#8217;t have to be Tiger Woods to want to keep your private life private. I hope the Vanish team succeeds.</p>

		<description><![CDATA[<p></p><p>Greg Reyes, former CEO of Brocade, received a sentence of 18 months and a $15 million dollar fine for his conviction on 10 felony counts related to options backdating. Prosecutors had asked for 37 months and a $137 million dollar fine. Mr. Reyes was emotional at his sentencing:</p>
<blockquote><p>
When Reyes got his opportunity to address Breyer, he stood at the lectern silently for a few seconds, and then broke down sobbing. [His attorney] read his statement for him.</p>
<p>&#8220;I am a shell of the man I once was,&#8221; he read.</p>
<p>Breyer said he was quite moved by the 400 letters sent in on Reyes&#8217; behalf, as well as the financial and emotional support he extends toward others. Yet a message must be sent to executives that deceiving the public markets is a serious crime, Breyer said.</p>
<p>The judge cited one more reason for a prison term.</p>
<p>&#8220;White-collar defendants, unlike most defendants I see in court every day, have choices,&#8221; Breyer said, adding that he had just sentenced a man to more time than Reyes because he illegally re-entered the United States to see his 5-year-old son.</p>
<p>In two weeks, Breyer will sentence another man whose drug addiction began when his father shot him up with heroin when he was 11.</p>
<p>&#8220;What choices did that young boy have?&#8221; Breyer said.
</p></blockquote>
<p>[From <a href="http://www.law.com/jsp/article.jsp?id=1202462995458&#038;Blaming_Lawyers_No_Stay_Out_of_Jail_Card_for_Former_CEO" target="_blank">Law.com</a>]</p>
<p><strong>The best CEO of any high tech company?</strong><br />
I met Mr. Reyes a couple of times when both of us wanted Sun to buy FC switches to make Sun&#8217;s early FC array more maintainable. I was at Sun at the time. He was an excellent salesman, but some idiot had decreed no FC switches for the storage group. </p>
<p><a href="http://www.storagenewsletter.com/news/people/brocade-ceo-greg-reyes-in-prison" target="_blank">Storage Newsletter</a> had an odd bit of history as well:</p>
<blockquote><p>
In 2002, we asked Steve Duplessie, well known consultant, to told [sic] us who was the best CEO in the storage industry. His answer: &#8220;[The best CEO] would be Greg Reyes of Brocade.&#8221;"
</p></blockquote>
<p>The 2 critical success factors for salesman are: a capacity for self-delusion &#8211; so you can <i>sincerely</i> and <i>honestly</i> tell your prospects how good it is; and a resolutely short term focus, because making this quarter&#8217;s numbers is what counts. Don&#8217;t hire a salesman to design your products or your strategy.</p>
<p><strong>The StorageMojo take</strong><br />
Given Brocade&#8217;s current problem &#8211; they&#8217;ve been for sale for over 9 months and there are no takers &#8211; and his own, Mr. Reyes was no strategist. But Brocade&#8217;s IPO timing made fortunes for Mr. Reyes and co-founders Paul Bonderson and Kumar Malavalli. Isn&#8217;t that what really counts?</p>
<p>But Mr. Reyes can be forgiven if he feels unfairly singled out. Here we are 2 years after after the big Wall Street meltdown, where the big ibanks were packaging and selling crap and calling it gold, when mortgage companies and rating agencies had gone wild, and who&#8217;s gone to jail for that?</p>
<p>At the same time, Maher Arar, a Canadian who was arrested in 2002 by U.S. officials while changing planes in New York on a trip to Montreal and then rendered by US officials to a Syrian jail was denied a hearing by the US Supreme Umpires. According to the findings of fact, Mr. Arar</p>
<blockquote><p>
 . . . was in Syria for a year, the first ten months in an underground cell six feet by three, and seven feet high. He was interrogated for twelve days on his arrival in Syria, and in that period was beaten on his palms, hips, and lower back with a two-inch-thick electric cable and with bare hands.
</p></blockquote>
<p>So buck up, Mr. Reyes, things could be worse. In 18 months you will have paid your debt to stockholders and you will still be among the richest 30,000 or so people in the world. </p>
<p><strong>Courteous comments welcome, of course.</strong> America is a nation of laws, not of men, unless the men are fighting terrorism. </p>

		<description><![CDATA[<p></p><p>Storage Newsletter reports that <a href="http://www.storagenewsletter.com/news/tapes/sccg-tape-2009" target="_blank">Tape Drive and Media Revenues Decreased by 25% in 2009</a>. The data comes from a report by the <a href="http://www.sccg.com/" target="_blank">Santa Clara Consulting Group</a>.</p>
<p>The numbers show us how old tape formats die: slowly. While the overall market for drives and media was $1.58B it was split among LTO, DLT, DAT, 8mm and even, gasp, QIC. </p>
<p>The good news: drive sales were $629M, suggesting that media sales will continue for years to come. LTO had over 83% of drive sales &#8211; $534M &#8211; with DAT (!) drives making most of the rest &#8211; $69M &#8211; and DLT much of the remainder. </p>
<p>The media numbers are revealing. Overall, media sales were only about 50% greater than drive sales or $955M. But in the case of DAT, media sales of $45M were less than drive sales. Buyers aren&#8217;t making much use of their new drives.</p>
<p>8 mm and QIC bring up the rear. Somebody bought over a million units of AIT media and over $16M of QIC media.</p>
<p><strong>The StorageMojo take</strong><br />
The long tail of tape is longer than I&#8217;d thought. There must be ancient systems out in retail or OEM equipment that use the media. Military, too.</p>
<p>But why that 25% drop in the overall tape market? I&#8217;d need more time series data to draw any firm conclusions, but here&#8217;s what I&#8217;d look at:</p>
<ul>
<li>The Great Recession. The overall slowing in business and capital expenditures is a piece of that. But the world economy did not decline 25%, thank goodness, so that can&#8217;t be the full cause.</li>
<li>D2D. Data de-duplication is aimed at making disk competitive with tape. Looks like 2009 was the year it took a byte out of tape.</li>
<li>Tape capacity growth. The LTO folks have been increasing LTO tape capacity at a rate near that of disk. More data, fewer tapes. Disks, of course, wear out, so the replacement market is huge. </li>
<li>Drive cost. At $3-$4k for an LTO 5 drive and $125 per 3 TB tape, the use of tape is moving upmarket, which means smaller volumes.</li>
</ul>
<p>Some people <a href="http://www.endlessanalog.com/what-is-clasp" target="_blank">love what tape does</a>. But others don&#8217;t: I haven&#8217;t seen a new tape <i>or</i> disk-based camcorder introduced in over a year. Everyone is going to flash.</p>
<p>$1.5B markets don&#8217;t die overnight &#8211; even dropping 25% a year. Tape will be around for a long time to come. </p>
<p><strong>Courteous comments welcome, of course.</strong>  I kicked off DLT for DEC back in 1991 and have always wondered why Quantum just rolled over for LTO instead of fighting. Oh well.</p>

<p>Some people <a href="http://www.endlessanalog.com/what-is-clasp" target="_blank">love what tape does</a>. But others don&#8217;t: I haven&#8217;t seen a new tape <i>or</i> disk-based camcorder introduced in over a year. Everyone is going to flash.</p>
<p>$1.5B markets don&#8217;t die overnight &#8211; even dropping 25% a year. Tape will be around for a long time to come. </p>
<p><strong>Courteous comments welcome, of course.</strong>  I kicked off DLT for DEC back in 1991 and have always wondered why Quantum just rolled over for LTO instead of fighting. Oh well.</p>

		<description><![CDATA[<p></p><p><a href="http://www.kaminario.com/" target="_blank">Kaminario</a> has introduced the world&#8217;s fastest SAN storage, the K2. If time is money, this is for you.</p>
<p><strong>DRAM</strong><br />
Kaminario&#8217;s K2 is fast because DRAM, not disk, is the primary storage. DRAM&#8217;s low latency, high bandwidth and durability breaks the tight link between capacity and performance that disks and flash impose. No need for excess capacity to ensure enough IOPS, bandwidth or service life.</p>
<p><strong>The product</strong><br />
Kaminario is a software company. However, they configure customer systems and install the software to order. No home-baked integration here. </p>
<p>The basic hardware unit is a Dell blade server. The blade servers are either I/O directors or data nodes. The Dell server chassis is a passive box &#8211; no active components on the backplane &#8211; but some customers opt for dual chassis for redundancy out of caution.</p>
<p><strong>I/O directors</strong><br />
The I/O directors use 8 gig Fibre Channel to servers and 10Gig/Ethernet to data nodes. The company says they can saturate both due to proprietary software optimizations.</p>
<p>Using FC switches, each I/O director can talk to multiple servers. Each I/O director can handle 150,000 random IOPS.<br />

</div><br />
<strong>Data nodes</strong><br />
Each data node supports up to 288 GB of ECC DRAM. All the data nodes have battery backup and 2 disks for de-staging data to persistent storage. Background de-staging during idle time reduces backup times during power failures.</p>
<p>The minimum config is 2 I/O directors and 4 data nodes with 500 GB of capacity. That&#8217;s 300,000 IOPS. They&#8217;ve been tested to 10 nodes and 1.5 million random read/write IOPS with support for 16 nodes &#8211; and double the IOPS &#8211; reportedly coming soon.</p>
<p><strong>Under the covers</strong><br />
The I/O directors are clustered so when 1 fails the others pick up the load. The switched back end 10Gig Ethernet enables all I/O directors to access all data nodes.</p>
<p>The replication default is 2 copies of all data on different blades. Plus copies on disk. </p>
<p>All this runs on standard Dell blade servers. No specialized, low-volume RAID controllers or power-hungry disk shelves. </p>
<p><strong>Software</strong><br />
The secret sauce is the software. Kaminario doesn&#8217;t say much about how they do what they do. In any high-performance cluster maintaining metadata coherence across nodes is one of the tough problems.</p>
<p>They did say they maintain hash tables that enable very short updates to all I/O directors after writes. I also suspect they also have implemented a low latency backend update protocol. Metadata serving is distributed across the cluster.</p>
<p>They must also have some creative ways to max out FC links. I&#8217;d like to know more.</p>
<p><strong>Management</strong><br />
With storage this fast they say you need little tuning. Lay LUNs across the data nodes and fasten your seatbelt. The software includes optimizations, like pseudo-random block layout to minimize contention, automatic load balancing and demand-based block replication. </p>
<p>If your app calls for it you can tune chunk sizes and set replication policies. Kaminario says K2 is much easier to manage than typical high-performance storage &#8211; you don&#8217;t have to worry about disk-induced issues like stride.</p>
<p>Management is kept out of the data path on a dedicated GigE network.</p>
<p><strong>Support</strong><br />
Kaminario says they have designed the product and their organization to provide mission-critical Enterprise support. The visible elements from configuration control and software installation to phone home and remote diagnostics back that up.</p>
<p><strong>Who needs this?</strong><br />
If you are hammering a few TB of data for stock trading, real-time business intelligence or TLA government work, this could be the ticket.</p>
<p><strong>Pricing</strong><br />
If you have to ask. . . .</p>
<p>Kaminario has a unique approach: pay for performance:</p>
<blockquote><p>
. . . we price the solution based on the customer IOPS and capacity needs, so basically the way we present such a platform price is by $/GB/IOPS.
</p></blockquote>
<p>I *think* small configs start around $200k. For the performance market price is something like #7 on the list. The first 3 are performance/availability &#8211; 2 sides of the same coin, really.</p>
<p>This removes SPEC shadow puppetry between application requirements and storage performance. Of course, you have to know what performance you want. But anyone who&#8217;s performance tuning high-end arrays will know that.</p>
<p><strong>The StorageMojo take</strong><br />
Kaminario is opening a new niche at the performance end of the market.</p>
<p>The current Big Storage vendors claim that they too can do a million IOPS. And they can, for millions. A price that makes a few TB of DRAM look cheap.</p>
<p>Since high-end disk &#8211; ≈$1/GB retail &#8211; makes up 5-10% of the cost of a high-end array, replacing disk with DRAM might be expected to double the cost of an array. But K2 does away with all the low-volume kit &#8211; controllers, shared cache, disk packaging and more &#8211; and replaces it with high-volume blade hardware. That lowers costs a lot.</p>
<p>Kaminario has opened a new niche: hyper-performance data storage. While a few TB doesn&#8217;t sound like much, it is more text than all but the world&#8217;s largest libraries place on miles of shelves.</p>
<p>The data arms race has kicked up another few notches. It is more competition for the big iron arrays where they least expected it: at the high-end of the market. </p>
