Own File Server

2011-01-26T19:51:00.000-08:00

generates large amounts of data needs a file server so that users can access it all from a central location. The sole purpose of a file server is to provide the users on the network with files. Additionally, file servers can also provide data to other users over the internet via a website or FTP service. A file server is nothing but a simple computer with ample storage space, running a server operating system and configured with data backup or synchronizing software. The hardware is usually designed using special purpose processors, RAM, motherboards, hard drives, power supply units and cabinets so the server is able to be powered on 24x7. So they have to be rugged and efficiently cooled too.

The main component of a server is the storage space, but using a single spacious hard drive will not serve the purpose. The drives should also be highly efficient in terms of speed, should have a large volume, and last but not the least, they should be secure enough to keep your data safe. Hence, they are usually configured in RAID, where multiple hard drives are deployed to ensure speed and safety during data transfers. Hard drives can be configured in RAID using different modes— RAID 0, 1, 5, 10 or 01. While RAID 0 is considered the fastest as it uses the data striping feature, RAID 1 is the safest as it uses data mirroring. but both have their advantages and disadvantages. RAID 5, 10 and 01 are combinations, which uses both striping and mirroring to form fast and safe storage. We will show you how to configure a simple file server which uses RAID 0 or RAID 1 using two SATA hard drives and an old computer. You can also use multiple hard drives to form a RAID 5, 10 or 01 volume.

Note: To create a RAID volume, the hard drives must be of the same type, speed and capacity, otherwise the one with the lesser of these features will bring down the efficiency of the entire group.

A file server is usually untouched, except for maintenance such as application installation, user configuration or fixing breakdowns. You can build your own server and leave it behind a desk, in a loft or hidden inside a cabinet, but the place it's set up in should be spacious, well ventilated and easily accessible for maintenance. The monitor, keyboard and mouse can be disconnected until required.

Requirements

Any old desktop computer. A Pentium 4 or higher is preferable.
Two or more similar SATA hard drives.
2 GB RAM should be enough, unless you have more to spare.
A PCI SATA RAID card, unless your motherboard features built-in RAID.
An operating system. A server edition is highly recommended if there are many users accessing it.

Let’s begin. Open and clean the old computer thoroughly and ensure a dust-free interior for efficient cooling. Install a PCI SATA RAID card into a vacant PCI expansion slot and screw it in place, unless your motherboard features an onboard RAID controller. Install the two (or more) hard drives in the respective bays and connect the necessary cables (data and power). Confirm that all cables are neatly tied and tucked away from the cooling fans and ducts to ensure proper air circulation. Once done, your hardware is ready to become a server.

Now is the time to install the operating system, but before this, you will need to configure the hard drives in RAID. If your motherboard features RAID, then simply go to the BIOS setup and configure the two hard drives in RAID 0 or 1 and exit.

If you are using a PCI RAID card, then you will have to press the necessary keys displayed on the screen while the system is starting up to enter the card’s BIOS. Here again, configure the hard drives in RAID and save the settings. You’re finally done configuring the hardware. If you want a secure storage system, use the RAID 1 configuration, and if speed is the requirement, go for RAID 0.

Note: Hard drives in RAID 0 will allow the total combined capacity to be used while RAID 1 offers half the combined storage space. For Example:
RAID 0: 80 GB + 80 GB = 160 GB and RAID 1: 80 GB + 80 GB = 80 GB.

speed up internet

2010-10-17T11:47:00.000-07:00

Speed up ur internet speed
Microsoft reserves 20% of your available bandwidth for their own
purposes like Windows Updates and interrogating your PC etc

You can get it back:

Click Start then Run and type "gpedit.msc" without quotes.This opens
the group policy editor. Then go to:
Local Computer Policy
then Computer Configuration
then Administrative Templates then Network then QOS Packet Scheduler
and then to Limit Reservable Bandwidth.
Double click on Limit Reservable bandwidth. It will say it is not
configured, but the truth is under the 'Explain' tab i.e."By default,
the Packet Scheduler limits the system to 20 percent of the bandwidth
of a connection, but you can use this setting to override the
default."
So the trick is to ENABLE reservable bandwidth, then set it to ZERO.
This will allow the system to reserve nothing, rather than the default
20%. 6/30/07 Ben.T.Ge?rge,
Increase the speed of your internet connection...
As more and more people get quick connections to the internet, such as
cable or ADSL, it becomes apparent to the user of a simple dial-up
modem that the World Wide Web can quickly turn into the World Wide
Wait. Here a trick that can help speed up your current modem without
shelling out the big bucks.
There is a setting located in your windows registry called the Maximum
Transfer Unit (MTU). This determines the size of the packets of data
sent between your and your server. In Windows 95, this setting is has
a value of 1,500 bytes when the actual size of internet packets is
1,000 bytes. This can sometimes slow things down. To remedy the
situation, simply follow these steps:

In the registry editor (Start > Run > regedit.exe), navigate to
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\NetTrans.
In the NetTrans folder you should find another folder named "000x" in
which x represents a fourth digit. Right-click on the "000x" folder
and select New and StringValue. Rename the item that appears in the
panel on the right side to MaxMTU, then double-click it to bring up
the Edit String box and give it a velue of 1002.

Remember to keep playing with the MaxMTU value until you feel that
your internet connection has greatly sped up. Some people report huge
speed gains using this tricks, while others hardly notice a
difference. In any case, it's definetly worth a try.

Intel Core is a brand name used for various mid-range to high-end consumer and business microprocessors.
In general, processors sold as Core are more powerful variants of the same processors marketed as entry-level Celeron and Pentium. Similarly, identical or more capable versions of Core processors are also sold as Xeon processors for the server market.

The current lineup of Core processors includes the latest Intel Core i7, Intel Core i5 and Intel Core i3, and the older Intel Core 2 Solo, Intel Core 2 Duo, Intel Core 2 Quad and Intel Core 2 Extreme lines.^[1]

The original Core brand refers to Intel's 32-bit mobile dual-core x86 CPUs that derived from the Pentium M branded processors. The processor family used a more enhanced version of the Intel P6 microarchitecture. It emerged in parallel with the NetBurst microarchitecture (Intel P68) of the Pentium 4 brand, and was a precursor of the 64-bit Core microarchitecture of Core 2 branded CPUs. The Core brand comprised two branches: the Duo (dual-core) and Solo (Duo with one disabled core, which replaced the Pentium M brand of single-core mobile processor).
The Core brand was launched on January 6, 2006 by the release of the 32-bit Yonah CPU – Intel's first dual-core mobile (low-power) processor. Its dual-core layout closely resembled two interconnected Pentium M branded CPUs packaged as a single die (piece) silicon chip (IC). Hence, the 32-bit microarchitecture of Core branded CPUs – contrary to its name – had more in common with Pentium M branded CPUs than with the subsequent 64-bit Core microarchitecture of Core 2 branded CPUs. Despite a major rebranding effort by Intel starting January 2006, some computers with the Yonah core continued to be marked as Pentium M.
The Core series is also known for being the first Intel processor to be used as the main CPU for an Apple Macintosh computer. The Core Duo was the CPU for the first generation Macbook Pro while the Core Solo appeared in Apple's Mac Mini line. Core Duo signified the beginning of Apple's shift to Intel processors across their entire line.
In 2007, Intel began branding the Yonah core CPUs intended for mainstream mobile computers as Pentium Dual-Core. These are not to be confused with the desktop 64-bit Core microarchitecture CPUs also branded as Pentium Dual-Core.
September 2007 and January 4, 2008 mark a discontinuation of many Core branded CPUs

The successor to Core is the mobile version of the Intel Core 2 line of processors using cores based upon the Intel Core microarchitecture,^[6] released on July 27, 2006. The release of the mobile version of Intel Core 2 marks the reunification of Intel's desktop and mobile product lines as Core 2 processors were released for desktops and notebooks, unlike the first Intel Core CPUs that were targeted only for notebooks (although some small form factor and all-in-one desktops, like the iMac and the Mac Mini, also used Core processors).
Unlike the Intel Core, Intel Core 2 is a 64-bit processor, supporting Intel 64. Another difference between the original Core Duo and the new Core 2 Duo is an increase in the amount of Level 2 cache. The new Core 2 Duo has tripled the amount of on-board cache to 6 MB. Core 2 also introduced a quad-core performance variant to the single- and dual-core chips, branded Core 2 Quad, as well as an enthusiast variant, Core 2 Extreme. All three chips are manufactured at a 65 nm lithography, and in 2008, a 45 nm lithography and support Front Side Bus speeds ranging from 533 MHz to 1600 MHz. In addition, the 45 nm die shrink of the Core microarchitecture adds SSE4.1 support to all Core 2 microprocessors manufactured at a 45 nm lithography, therefore increasing the calculation rate of the processors.

On September 8, 2009, Intel released the first Core i5 processor: The Core i5 750,^[1] which is a 2.66 GHz quad-core Lynnfield processor with Hyper-threading disabled. Lynnfield Core i5 processors have an 8 MB L3 cache, a DMI bus running at 2.5 GT/s and support for dual-channel DDR3-800/1066/1333 memory. The same processors with different sets of features (Hyper-Threading and other clock frequencies) enabled are sold as Core i7-8xx and Xeon 3400-series processors, which should not be confused with high-end Core i7-9xx and Xeon 3500-series processors based on Bloomfield.

The Core i5-5xxx mobile processors are named Arrandale and based on the 32 nm Westmere shrink of the Nehalem microarchitecture. Arrandale processors have integrated graphics capability but only two processor cores. They were released in January 2010, together with Core i7-6xx and Core i3-3xx processors based on the same chip. The L3 cache in Core i5-5xx processors is reduced to 3 MB, while the Core i5-6xx will use the full cache and the Core i3-3xx will have no support for Turbo Boost^[2]. Clarkdale, the desktop version of Arrandale, is sold as Core i5-6xx, along with related Core i3 and Pentium brands. It has Hyper-Threading enabled and the full 4 MB L3 cache.^[3]

i7 processor

2010-10-08T19:43:00.000-07:00

Intel Core i7 is an Intel brand name for several families of desktop and laptop 64-bit x86-64 processors using the Nehalem, Westmere, and upcoming Sandy Bridge microarchitectures. The "Core i7" brand is marketed for the business and high-end consumer markets and is intended to differentiate these processors from Core i5 processors intended for the main-stream consumer market and Core i3 processors intended for the entry-level consumer market.
"Core i7" is a successor to the Intel Core 2 brand.^[1]^[2]^[3]^[4] The Core i7 identifier was first applied to the initial family of processors^[5]^[6] codenamed Bloomfield introduced in 2008. In 2009 the name was applied to Lynnfield and Clarksfield models.^[7] Prior to 2010, all models were quad-core processors. In 2010, the name was applied to dual-core Arrandale models, and the Gulftown Core i7-980X Extreme processor which has six hyperthreaded cores.

Intel representatives state that the moniker Core i7 is meant to help consumers decide which processor to purchase as the newer Nehalem-based products are released in the future.^[8] The name continues the use of the Intel Core brand.^[9] Core i7, first assembled in Costa Rica,^[10] was officially launched on November 17, 2008^[11] and is manufactured in Arizona, New Mexico and Oregon, though the Oregon (PTD, Fab D1D) plant has moved to the next generation 32 nm process.
