Battle Rig improvements

The lates additions to the all and mighty gaming rig follows 😛

Logitech G5

The G5 uses a laser tracking engine as opposed to the LED or photodiode systems used by some other mice. It supports up to 5 resolution presets which can be set between 400 dpi and 2000 dpi, in 50 dpi increments. The G5 includes Teflon feet.

Logitech G15

The Logitech G15 is a keyboard produced by Logitech designed specifically for gamers. It includes 18 macro keys that can each have 3 macros assigned to them and a backlit monochrome LCD display (Which can show helpful information from compatible applications to the user). Logitech distributes a SDK for the LCD display panel on the keyboard’s drivers disc which can be used to add G15 compatibility to applications.

Project S.A.N. – The Begining

In computing, a storage area network (SAN) is an architecture to attach remote computer storage devices (such as disk arrays, tape libraries and optical jukeboxes) to servers in such a way that, to the operating system, the devices appear as locally attached.

So what does it consist of … well who knows, so then i go poking around the net.. looking for clues as to how build one from scratch. So looking into what exactly a SAN is… well think of it as your office store room… everyone stores their stuff in it, and hopefully its huge so u have lots of space.And if anyone find it becoming too small.. u just make the storeroom bigger and everyone benefits from this. SAN is just like this.. but instead of room space we have disk space.

So here goes… what you have been waiting for… what does a SAN consit of…

Fiber Channel Switches (aka SAN Fabric)

Since switches form the intelligent foundation of your SAN, it’s important to select the right ones for your business requirements.

Storage Devices

There are many types of disk and tape storage devices available that meet a wide variety of storage requirements. Make sure the devices are Fibre Channel ready. Integrating a variety of devices into your SAN allows you to allocate storage based upon cost, availability, and performance criteria. If critical application data is stored on a device, you’ll want to have that device dual-attached to your fabric to ensure high availability. That requires double the number of Fibre Channel connections on that device.

Host Bus Adapters (HBAs)

The requirements of the applications that will run on your SAN should help drive what type of HBAs you need on your hosts. From the available 1 Gbit/sec, 2 Gbit/sec, and auto-sensing speeds, choose the speed needed to match your current and future data throughput requirements. If critical applications are running on a host, you’ll want to have that host dual-attached to your fabric to ensure high availability. That requires double the number of HBAs for that host.

Cabling

Copper and optical are the two primary types of media used for the physical cabling between the components of your SAN. While copper is less expensive, optical provides a reliable signal over a longer distance. Copper has distance limitations such that it is typically only used within a rack.

To give u an idea… here is what a SAN System would look like…
