If you are familiar with the parts of a desktop computer, you’ll not have a hard time guessing the parts of a server computer. Basically, it has a CPU, RAM, Motherboard, Hard Drive, cables and many others, though most of the time; it doesn’t have a fancy monitor and a high accuracy keyboard and mouse. As for those who want to jump right into server computing business or those who wants a refresher on what these parts do, you’ve come to the right place. I will discuss the parts of a server computer to help you master and understand how a server computer works. Let’s begin.
The mother of everything, it’s the PCB or main circuit board that connects all components of a server computer. It also holds some of the important components like RAM and CPU. If you think about it clearly, the motherboard is the computer as all other components rely to the mother to make their calculations and operation maximized, optimized and perfectly accurate.
The major components of a mother board includes a processor or the CPU, a chipset, memory, expansion slots, IDE hard drive controller, I/O or input/output ports for devices like keyboards, printers and the like.
One distinguishing feature of server motherboards is that you can have two physical CPUs in a single motherboard, a thing that, as of this writing, you can never find on a desktop PC, though you can create your own customized one if you have the skills.
This is where all calculations, logic and decision making happens. It’s the brain of the server. Server processors are slightly different from desktop processors in terms of architecture. Generally, they have slower clock speeds but they have way more number of cores, with some arriving at 20 cores compared to eight cores of the most modern desktop processors.
Different motherboards support different types of processor. If you are going to upgrade your CPU to a different line of release, e.g. from Xeon to Itanium, you’ll have to replace your motherboard.
RAM or Memory
If your desktop PC can be considered as an overkill for having 16GB of RAM, a server computer can easily fill that up. Most server motherboards can support up to 128GB of RAM for maximum performance.
HDD or Hard Disk Drives
IDE drives are used for desktop computers, sometimes, ATA. However, for servers, you’ll use an SCSI drive. They offer performance that is more powerful and can greatly speed up if paired with an SCSI controller card.
One of the most important thing for a server, they must have a very fast network connection and card. Most server motherboards come with a high-speed network card.
