Components of a Server Computer



Components of a Server Computer

The hardware components that make up a typical server computer are similar to the components used in less-expensive client computers.
However, server computers are usually built form higher-grade components than client computers for the reason given in the preceding section.
 The following paragraphs describe the typical components of a server computer.

Motherboard: A motherboard is the computer's main electronic circuit board  to which all other components of your computer are connected. More than any other components, the motherboard is the computer. All other components attach to the motherboard.
The major components on the motherboard include the processor (CPU);
supporting circuitry (the chipset); memory (RAM); expansion slots: a standard IDE hard drive controller; input/output (I/O) ports for devices such as keyboards, mice,and printers; a grap-hics adapter; and one or more network interfaces.

Processor: The CPU is the brain of the computer . Although the processor isn't the only  component that affects overall syastem performance, it's the one that most people think of first when deciding what type of server to purchase. At the time of this writing, intel had two processor models specifically designed for use in server computers:

1. Itanium 9300:4 or 8 cores, 1.73 to 2.53GHz
2. Xeon: 4 to 18 cores, 1.9 to 3.2 GHz

Each motherboard is designed to support a particular type of processor. CPUs come in two  basic mounting styles: slot or socket. However, you can choose from several types of slots and sockets, so you have to make sure that the motherboard supports the specific slot or sockets style used by the CPU. Some server motherboards have two or more slots or sockets to hold two or more CPUs.

Memory: Dont't Scrimp on memory . People rarely complain about servers having too much memory. Many different types of memory are available so yoyu have to pic kthe right type of memory to match the memory supported by your motherboard. The total Memory capacity of the server depends on the motherboard. It isn't unusual to see servers configured with anywhere from 32GB to 512 GB of RAM.

Hard drives: Most desktop computers use inexpensive  consumer-grade SATA hard drives, which are adequate for individual users . Because of their low cost. SATA drives are sometimes also used in inexpensive  servers. But because performance and reliability are important in servers, many servers, rely on faster and more reliable SCSI or Serialld Attached SCSI (SAS) disk drives instead.

Network Interfaces: The network connection is one of the most important parts of any server. Ideally, your server should have at least two network interfaces. Additional Networks interfaces not only improve the performance of our server, but also make it more reliable : If one of the network interfaces. Additional network interfaces not only improve the performance of your server, but also make more reliable: if one of the network interfaces should fail, the others can pick up the ball.

Video: Fancy graphic aren't that important for a server computer. You don't need to equip your server with a fancy video card; the iveo interface that's built in to the motherboard will suffice. (This is one of the few areas where it acceptable to cut costs on a server.

Power Supply: Because a server usually has more devices than a typical desktop computer, it requires a larger power supply (typically 600 watts) If the sever houses a large number of hard drives, it may require an even larger supply.
Because the power supply is one of the most likely components to fail, many server computer have two built-in power supplies for redundancy . That way, if one of the power supplies should fail, the other can pick up the load and keep the server running.
