In this article, we will discuss the seven major components of a Server Rack. However, before moving into the primary section of this article, we will briefly explain to you what a Server rack is. Therefore, if you are eager to gather valuable information regarding Server Racks, thoroughly go through this article.

What is a Server Rack?

A server rack is a particular type of rack which is primarily designed to hold and organize IT equipment. People prefer to stack servers and other IT equipment in a rack because it helps to keep things organized and also helps to control the airflow.

7 Primary components of a Server Rack

The seven primary components of a Server Rack are:

  • Motherboard
  • RAM
  • CPU
  • Host Bus Adapter
  • I/O Ports
  • Drive Bays
  • Supporting Equipment

The motherboard, also known as the system board, enables communication between components via data buses.

RAM or random access memory, also known as server memory, is a primary part of any server rack. The more RAM slots a server rack possesses more RAM modules you can add. If the number of RAM modules is more, there is less chance of bottlenecking which eventually increases the speed of data access.
CPU or the central processing unit, also known as the processor, is responsible for executing the start instruction.
Host Bus Adapter (HBA)

An HBA or Host Bus Adapter is another essential part of a server rack that primarily connects external devices to the server.

I/O Ports

The USC, Serial port, and AUX port are the server rack’s input/output ports that are embedded into the system board.

Drive Bays

Drive Bays is an essential component that adds hard drives (HDD) and Solid State Drives (SSDs) to the server.

Supporting Equipment

Supporting equipment includes rails, cable management bars, and fans that prevent the server rack from overheating.


As promised at the beginning of this article, we have discussed about the seven main components of a Server Rack. So, thoroughly review the article, and learn about the functions of a Server Rack’s seven primary components.
