Are large storage arrays dead at the hands of SSD?

Thu, 17 May 2012 12:34:56 CST

Are large storage arrays dead at the hands of SSD?

By Greg Schulz

An industry trends and perspective.

Are large storage arrays dead at the hands of SSD? Short answer NO not yet.
There is still a place for traditional storage arrays or appliances particular those with extensive features, functionality and reliability availability serviceability (RAS). In other words, there is still a place for large (and small) storage arrays or appliances including those with SSDs.

Is there a place for newer flash SSD storage systems, appliances and architectures? Yes
Similar to how there is a place for traditional midrange storage arrays or appliances have found their roles vs. traditional higher end so-called enterprise arrays. Think as an example EMC CLARiiON/VNX or HP EVA/P6000 or HDS AMS/HUS or NetApp FAS or IBM DS5000 or IBM V7000 among others vs. EMC Symmetric/DMX/VMAX or HP P10000/3Par or HDS VSP/USP or IBM DS8000. In addition to traditional enterprise or high-end storage systems and midrange also known as modular, there are also specialized appliances or targets such as for backup/restore and archiving. Also do not forget the IO performance SSD appliances like those from TMS among others that have been around for a while.

Blog post: Storage and IO metrics that matter

Thu, 3 May 2012 16:54:32

Storage and IO metrics that matter

By Greg Schulz

It is great to see more conversations and coverage around storage metrics that matter beyond simply focusing on cost per GByte or TByte (e.g. space capacity). Likewise, it is also good to see conversations expanding beyond data footprint reduction (DFR) from a space capacity savings or reduction ratio to also address data movement and transfer rates. Also good to see is increase in discussion around input/output operations per section (IOPs) tying into conversations from virtualization, VDI, cloud to Sold State Devices (SSD).

Is SSD dead? No, however some vendors might be

By Greg Schulz

In a recent conversation with Dave Raffo about the nand flash solid state disk (SSD) market, we talked about industry trends, perspectives and where the market is now as well as headed. One of my comments is, has been and will remain that the industry has still not reached anywhere near full potential for deployment of SSD for enterprise, SMB and other data storage needs. Granted, there is broad adoption in terms of discussion or conversation and plenty of early adopters.

SSD and in particular nand flash is anything but dead, in fact in the big broad picture of things, it is still very early in the game. Sure, for those who cover and crave the newest, latest and greatest technology to talk about, nand flash SSD might seem old, yesterday news, long in the tooth and time for something else. However, for those who are focused on deployment vs. adoption such as customers, in general, nand flash SSD in its many packaging options has still not yet reached its full potential.

Blog post: What is the best kind of IO? The one you do not have to do

Thu, 3 May 2012 16:54:32

What is the best kind of IO? The one you do not have to do

By Greg Schulz

If no IO (input/output) operation is the best IO, than the second best IO is the one that can be done as close to the application and processor with best locality of reference. Then the third best IO is the one that can be done in less time, or at least cost or impact to the requesting application which means moving further down the memory and storage stack.

Blog post: More Storage IO momentus HHDD and SSD moments part I

More Storage IO momentus HHDD and SSD moments part I

By Greg Schulz

This is the first of a two part series on my latest experiences with HHDD and SSD's

About two years ago I wanted to start installing solid state devices (SSD's) into my workstations and laptops. Like many others, I found the expensive price for the limited capacity gains of the then generation SSD's did not make for a good business decision based on my needs. Dont get me wrong, I have been a huge fan of SSD for decades as an IT user, vendor, analysts, consultant and consumer and still am. In fact I have some SSD's used for different purposes as well as many Hard Disk Drives (HDD) and Hybrid Hard Disk Drives (HHDD's). Almost two years ago when I first tested the HHDD's, I did an first post in this ongoing series and this two-part post is part of that string of experiences observed evolving from HDD's to HHDD's to SSD's

Image courtesy of Seagate.com

As a refresher, HHDD's like the Seagate Momentus XT combine a traditional 7,200 RPM 2.5 inch 500GB or 750GB HDD with an integrated single level cell (SLC) nand flash SSD within the actual device. The SSD in the HHDD's is part of the HDD's controller complementing the existing DRAM buffer by adding 4GB (500GB models) or 8GB (750GB models) of fast nand flash SSD cache. This means that no external special controller, adapter, data movement or migration software are required to get the performance boost over a traditional HDD and the capacity above a SSD at an affordable cost. In other words, the HHDD's bridge the gap between those who need large capacity and some performance increases, without having to spend a lot on a lower capacity SSD.

More Storage IO momentus HHDD and SSD moments part II

By Greg Schulz

This follows the first of a two-part series on my latest experiences with Hybrid Hard Disk Drives (HHDD's) and Solid State Devices (SSD's). In my ongoing last momentus moment post I discussed what I have done with HHDD's and setting the stage for expanded SSD use. I have the newer HHDD's, e.g. Seagate Momentus XT II 750GB (8GB SLC nand flash) installed and have since bought another from Amazon as well as having some of the older 500GB (4GB SLC nand flash) in various systems. Those are all functioning great, however still waiting and looking forward to the rumored firmware enhancements to boost write capabilities.

This brings me up to the latest momentus moment which now includes SSD's.

Well its two years later and I now have a 256GB (usable capacity is lower) Samsung SSD that I bought from Amazon.com and installed in one of my laptops and just as when I made the first switch to HHDD's, I also have a backup copy/clone to fall back to in case of emergency.

Was it worth the wait? Yes, particularly using the HHDD's to bridge the gap and enable some productivity gain which more than paid for them based on some different projects. I'm already seeing productivity improvements that will make future upgrades more easy to justify (to myself).

IT Optimization, efficiency, convergence and cloud conversations from SNW

By Greg Schulz

Recently I did a presentation titled Cloud and Virtual Data Storage Networking (hmm, I think I know of a book with the same title) at the spring 2012 SNW in Dallas. My presentation was on the first morning of the session as I needed to be in Boston to record a video the following Tuesday morning, thus I missed out on the storm clouds and tornadoes that rolled in the next day.

While I was at SNW, had the honor of being a guest on Calvin Zito (aka @HPStorageguy) pod cast that can be found on his Around the Storage Block Blog or by clicking here.

Check out our conversations about clouds, related topics and more from a practical perspective cutting through the hype and fud.

Oh, if you are interested in Cloud and Virtual Data Storage Networking, click here to learn more about the book, or here to find various downloads and associated presentations, and here to see some upcoming events, activities and venues both in the U.S. and in Europe.

Ok, nuff said for now.

Part I: PureSystems, something old, something new, something from big blue

By Greg Schulz

This is the first in a five-part series around the recent IBM PureSystems announcements. You can view the next post here.

For a certain generation of IBM faithful or followers the recently announced PureFlex and PureApplication systems might give a sense of DejaVu perhaps even causing some to wonder if they just woke up from a long Rip Van Winkle type nap.

Yet for another generation who may not yet be future IBM followers, fans, partners or customers, there could be a sense of something new and revolutionary with the PureFlex and PureApplication systems (twitter @ibmpuresystems).

In between those two groups, exist others who are either scratching their heads or reinvigorated with enthusiasm to get out and be able to discuss opportunities around little data (traditional and transactional) and big data, servers, virtualized, converged infrastructure, dynamic data centers, private clouds, ITaaS, SaaS and AaaS, PaaS, IaaS and other related themes or buzzword bingo topics.

Let us dig a little deeper and look at some So What types of questions and industry trends perspectives comments around what IBM has announced.

So what about the IBM Virtual Appliance Factory?
Where PureFlex and PureApplication (PureSystems) are the platforms or vehicles for enabling your journey to efficient and effective information services delivery, and PureSystem centre (or center for those of you in the US) is the portal or information center, the IBM Virtual Appliance Factory (VAF) is a collection of tools, technologies, processes and methodologies. The VAF helps developers or ISVs to prepackage applications or solutions for deployment into Kernel Virtual Machine (KVM) on Intel and IBM PowerVM virtualized environments that are also supported by PureFlex and PureApplication systems.

If March 31st is backup day, dont be fooled with restore on April 1st

By Greg Schulz

With March 31st as world backup day, hopefully some will keep recovery and restoration in mind to not be fooled on April 1st.

When it comes to protecting data, it may not be a headline news disaster such as earthquake, fire, flood, hurricane or act of man, rather something as simply accidentally overwriting a file, not to mention virus or other more likely to occur problems. Depending upon who you ask, some will say backup or saving data is more important while others will standby that it is recovery or restoration that matter. Without one the other is not practical, they need each other and both need to be done as well as tested to make sure they work.

Is 14.4TBytes of data storage for $52,503 a good deal? It depends!

By Greg Schulz

A news story about the school board in Marshall Missouri approving data storage plans in addition to getting good news on health insurance rates just came into my in box.

I do not live in or anywhere near Marshall Missouri as I live about 420 miles north in the Stillwater Minnesota area.

What caught my eye about the story is the dollar amount ($52,503) and capacity amount (14.4TByte) for the new Marshall school district data storage solution to replace their old, almost full 4.8TByte system.

That prompted me to wonder, if the school district are getting a really good deal (if so congratulations), paying too much, or if about right.

Blog post: Why SSD based arrays and storage appliances can be a good idea (Part I)

Tue, 13 Mar 2012 20:20:20

Why SSD based arrays and storage appliances can be a good idea (Part I)

By Greg Schulz

This is the first of a two part series, you can read part II here.

Robin Harris (aka @storagemojo) recently in a blog post asks a question and thinks solid state devices (SSDs) using SAS or SATA interface in traditional hard disk drive (HDD) form factors are a bad idea in storage arrays (e.g. storage systems or appliances). My opinion is that as with many things about storing, processing or moving binary digital data (e.g. 1s and 0s) the answer is not always clear. That is there may not be a right or wrong answer instead it depends on the situation, use or perhaps abuse scenario. For some applications or vendors, adding SSD packaged in HDD form factors to existing storage systems, arrays and appliances makes perfect sense, likewise for others it does not, thus it depends (more on that in a bit). While we are talking about SSD, Ed Haletky (aka @texiwill) recently asked a related question of Fix the App or Add Hardware, which could easily be morphed into a discussion of Fix the SSD, or Add Hardware. Hmmm, maybe a future post idea exists there.

Some alternative and fun Cloud API meanings

By Greg Schulz

Hearing different discussions about APIs in general and cloud in particular got me thinking, besides the usual Application Programming Interface meaning, what other options exists including those to have some fun with.

How about some of these among others to have some fun and take a quick break from the otherwise serious side of clouds, virtualization data and storage networking, backup, archive, VDI, data protection and management topics.

Cloud API = A Payment Invoice
Cloud API = A Paid Infrastructure
Cloud API = A Pain Inthea$$
Cloud API = A Pathto Income
Cloud API = A Pathto IOP
Cloud API = A Payment Infrastructure
Cloud API = A Planned Inconvenience
Cloud API = A Processor Interconnect
Cloud API = A Program Incubator
Cloud API = A Propriety Interface
Cloud API = A Protected Income
Cloud API = A Protected Investment
Cloud API = A Public Infrastructure
Cloud API = Aaas Paas Iaas
Cloud API = All Partners Involved
Cloud API = All Programmers Involved
Cloud API = Amazon Plus IBM
Cloud API = Another Product Inititiave
Cloud API = Another Program Interface
Cloud API = Another Programmer Innovating
Cloud API = Architect Planned Infrastructure

Researchers and marketers dont agree on future of nand flash SSD

By Greg Schulz

Marketers particular those involved with anything resembling Solid State Devices (SSD) will tell you SSD is the future as will some researchers along with their fans and pundits. Some will tell you that the future only has room for SSD with the current flavor de jour being nand flash (both Single Level Cell aka SLC and Multi Level Cell aka MLC) with any other form of storage medium (e.g. Hard Disk Drives or HDD and tape) being dead and to avoid wasting your money on them.

Of course others and their fans or supporters who do not have an SSD play or product will tell forget about them, they are not ready yet. Then there are those who take no sides per say, simply providing comments and perspectives along with things to be considered that also get used to spin stories for or against by others.

In addition EMC is also talking about the next phase of the flash business unit and project Thunder. The approach EMC is taking with vFCache should not be a surprise given their history of starting out with memory and SSD evolving it into an intelligent cache optimized storage solution.

Could we see the future of where EMC will take VFCache along with other possible solutions already being hinted at by the EMC flash business unit by looking where they have been already?

Likewise by looking at the past can we see the future or how VFCache and sibling product solutions could evolve?

After all, EMC is no stranger to caching with both nand flash SSD (e.g. FLASH CACHE, FAST and SSD drives) along with DRAM based across their product portfolio not too mention being a core part of their company founding products that evolved into HDDs and more recent nand flash SSDs among others.

IT and storage economics 101, supply and demand

By Greg Schulz

In my 2012 (and 2013) industry trends and perspectives predictions I mentioned that some storage systems vendors who managed their costs could benefit from the current Hard Disk Drive (HDD) shortage. Most in the industry would say that is saying what they have said, however I have an alternate scenario. My scenario is that for vendors who already manage good (or great) margins on their HDD sales and who can manage their costs including inventories stand to make even more margin. There is a popular myth that there is no money or margin in HDD or for those who sell them which might be true for some.

Without going into any details, lets just say it is a popular myth just like saying that there is no money in hardware or that all software and people services are pure profit. Ok, lets leave sleeping dogs lay where rest (at least for now).

Why will some storage vendors make more margin off of HDD when everybody is supposed to be adopting or deploying solid state devices (SSD). Or Hybrid Hard Disk Drives (HHDD) in the case of workstation, desktop or laptops? Simple, SSD adoption (and deployment) is still growing and a lot of demand generator incentives available. Likewise HDD demand continues to be strong and with supplies affected, economics 101 says that some will raise their prices, manage their expenses, make more profits which can be used to help fund or stimulate increased SSD or other initiatives.
