What are the Key Components of a Server?

Servers play an important role in your IT infrastructure. They are designed to send information to different computers linked to them through a network. They are modular components with the processing power to store and route data for various applications. Depending on the data center’s size, most businesses choose tower or rack servers. They can adjust the server count based on their needs. Before investing in the best server, it is essential to understand its components.

What are the main server components?

Whether you have chosen Dell R540 rack servers or tower servers, the major components are the same.


Motherboard is a PCB used for computing systems. It not only provides firmware but also holds a CPC. There are also secondary chips to manage processing and I/O ports. The motherboard is the main part of a server because other components are attached to it. It also works as the primary connection for other connected devices. It has a number of slots for expansion devices like graphic adapters.

A standard motherboard contains more than 10 fiberglass layers and copper planes. So, these parts facilitate signal isolation and power distribution. Low-profile Extension and Advanced Technology Extended are common types of motherboards. ATX consumes more space for LAN connections and I/O arrangements.


Random Access Memory works as a short-term memory needed to manage data and software instructions. It also deals with the output provided by the processor. As RAM is used for temporary storage, there is a risk of losing data and content when you remove power from the server. That is why your computer needs non-volatile or permanent storage when you turn off the system.

RAM chips need to be organized into modules, and it helps in adding the memory to the server during the memory failure. 

Hard Drive

If you prefer standard, reliable drives for good performance, SATA drives can be the best choice. However, with the advancement of hard drive technology, SSDs have become popular. Different types of server hosting are compatible with it. SSD is more efficient in terms of writing and reading speed. So, SSD will never affect your server performance.


As a type of processor chip, the Graphics Processing Unit holds multiple graphics processing cores that deal with computational activities. GPUs are available in different versions- discrete and integrated. The motherboard is integrated with a GPU, and you cannot replace or upgrade it. On the contrary, the discrete GPU needs to be fitted to your graphics card. Some users do not consider using GPUs for the server setup. However, if you want to deal with AI, ML, and other technologies, it is better to use GPUs.

Remote Access Card

This is specially designed hardware to secure remote and secure server management. The device helps IT managers update or deploy servers anytime and anywhere.

So, you have now learned about network server components essential for your IT setup. Before selecting the server, you have to determine your data storage and performance needs. Buy the best quality server for your IT infrastructure.
