Server Components

The hardware part of a typical dedicated server computer is almost the same as in the less expensive client computers. However, computers for servers typically collect the components of higher quality.

Motherboard

The motherboard is the main board of the computer connects to all other components.

The main components that reside on the motherboard are a processor (or CPU), auxiliary circuits, or chipset, memory, expansion slot, a standard IDE hard disk controller, and input / output ports (I / O) for these devices as keyboards, mice and printers. Some motherboards are distinguished by the presence of additional integrated features such as built-in graphics adapter, SCSI disk controller or network interface.

Processor

Processor, or CPU – is the brain of the computer. Although it is not the only component that affects the overall system performance, but choosing which server to buy, most people pay attention to in the first place on the processor. Intel offers different models of processors, designed for use in server computers:

• Itanium 2: The clock frequency of 1.60 GHz, 1-2 processor cores
• Xeon: clock speed of 1.83 – 2.33 GHz, 1.4 processor cores
• Pentium D: clock speed of 2.66 – 3.6 GHz, 2 CPU cores
• Pentium 4: Clock frequency 2,4 – 3,6 GHz, 1 CPU core

Each motherboard is designed to support processor-specific type. The processors come in two basic installation options: slot or socket. If you have a choice of different installation options, you need to pay attention to the type of connector where your motherboard match the type of conclusions of the processor. Some server motherboards contain two or more slots, and they can install two or more processors.

The term clock frequency means the frequency of the main clock, synchronizes the operation of the processor. Theoretically, the higher clock speed, the faster the processor. However, the magnitude of the clock frequency can be safely used only when compared to the same family of processors. In fact Itanium processors are faster than the Xeon processors with the same clock frequency. The same applies to Xeon processor, when compared with the Pentium D. Such differences can be explained by the fact that new processors models differ from the old advanced scheme, capable during each beat synchronization to perform more work.

Processor performance is strongly influenced by the number of processor cores. Each processor core functions as if it were a separate processor. In the majority of server computers used chips dual-core (two processor cores) and quad-core (four processing cores).
