Although the server can actually be made using the computer components on the market, especially for low-load or non-critical applications-a dedicated server, a mission critical usually use special hardware that is optimized for server needs.
A server can insert mechanical components with the power industry, such as hard disks or fans, which provide high reliability and performance and are usually expensive. Views are usually not considered, because the server will generally work without waiting in the computer room accessible only to the needs of a large hard disk repair, to obtain high reliability typically uses a smaller capacity hard disk diparalel some fruit.
On the server CPU speed is usually not as critical on the desktop. Most server capability will be more dependent on the speed I / O rather than CPU. In addition, most servers will not run a graphical user interface (GUI) so it will have a lot of residual ability to perform tasks - other tasks. Usually, if you must choose CPUs with high speed with a lot of CPU then a server will choose to have a lot of CPU than one CPU at high speed especially untu reliability and redundancy.
Gui is not used on the server so it can use ordinary video adapters. In addition, there is usually no sound card, joystick, and others - others who usually are not used on the server. Because of the need for operational and reliable continuous edge, then the fan angina efficient and reliable is needed. Indeed, the fan like this are usually quite noisy, not like a PC fan dirumahan are usually not noisy but not necessarily reliable untu operated 24 hours. Often the server room will require air conditioning to cool server. To ensure there is no problem with listris, usually used UPS (Uniterruptable Power Supply) which will operate during power failure.
This is great information. I have been looking for more information on server rooms and CRAC. This was such a helpful article. Thanks so much for sharing.
