5 Basic Server Components Need to Know

5 Basic Server Components Need to Know – Motherboard, CPU, Memory, Hard Disk & RAID Card

What is a server? 

Servers are high-performance computers engineered to store, process, and manage network data, systems, and devices. Server computers are dedicated entirely to managing networks that help deliver information and offer services to other server components interlinked through the network. These server computers are capable of catering to data-intensive and complex tasks that may include data-heavy websites, managing a large number of queries per minute, or setting up a shared drive for a department. The servers are responsible for hosting high-performing applications and software that a standard computer cannot cater to.

Additionally, servers act as powerful engines for organizations that offer scalable and efficient processors that provide businesses with sufficient resources for business continuity capabilities. These servers are crucial in sharing resources across the network, making the companies choose the best server solution for their enterprises. Therefore, several categories of servers include file servers, print servers, database servers, and network servers. In a nutshell, when computers share resources with client machines, they are considered servers.

Key Components of a Server

Finding the correct Server begins with understanding what a network server is. This blog elaborates on key components of a server, i.e., Motherboards, Processors, Memory, Hard Drives, and RAID Cards.



The motherboard is the essential component of a computer or Server. It is the main circuit board to which all other components are attached. A standard motherboard usually includes six to fourteen fiberglass layers, copper planes, and connecting traces. The size of a motherboard varies depending on the needs and requirements of the end user. Motherboards are usually designed with connectors for attaching peripherals, including keyboards, mouse, hard drives, and monitors. The motherboard also has slots for expansion cards such as sound cards, video cards, and network cards, among others. The server motherboard features firmware (BIOS) and an array of secondary chips that can handle I/O and processing support, such as a Serial Advanced Technology Attachment (SATA) or Serial-Attached SCSI (SAS) storage interface. Several motherboards have additional integrated features such as a built-in graphics adapter, SCSI disk controller, or network interface.

Server Processors 

Server Processors

Central Processing Units (CPU) or processor is the main brain of the computer system. Server CPUs are complex micro-circuitry device that is the core of all the operations performed on the device. The processors are responsible for sending and receiving signals to and from all components, such as memory, HDDs, and other components. The server processors can translate and execute the essential functions in a computing system: fetch, decode, execute and write back.

Further, the four main elements of processors usually include the registers and cache memory, followed by an arithmetic logic unit (ALU) that executes all the logic and arithmetic commands. In contrast, the floating point unit (FPU) is engineered for processing numbers faster than any traditional microprocessor circuit.

Server Memory

Server Memory

Server Memory helps with processing data from HDDs or SSDs to the CPU. Server RAM is volatile memory and can store data as long as the processor does not lose its power. Although, as far as performance is concerned, RAMs have faster data read-up and write-up speeds. The CPU usually looks for server RAM for instructions rather than searching the hard drive for data or instructions. These memory modules are more secure and consume less heat, making them durable and reliable. Server RAM’s capacity is considered an essential factor that influences the system’s performance. Shortage of server memory may lead to bottlenecks affecting the system’s efficiency. A server can support more Virtual Machines (VMs) with more memory. And upgrading the existing server memory can boost memory speed and bandwidth for faster data processing.

Server Hard Drives

Server Hard Drives

The server Hard disk is a data storage device used to store data, files, and media. It can be either magnetic or solid-state, and there are two types of server hard drives – internal and external. The built-in HDDs are also called the primary storage device for servers. It stores all the data in a file system on the hardware device;

Internal HDDs: Internal hard disks can be installed inside the computer case and are usually located close to the motherboard. These disks require no separate power supply but have limited space that cannot hold much data.

External HDDs: External Hard drives have a power supply unit, which makes them portable. They have higher capacities than internal HDD but are slower than internal ones because they use USB interfaces, while Internal ones use Direct Memory Access (DMA) channels because of proximity to motherboards.

Raid Controller Cards

Raid Controller Cards

RAID Controller Cards (Redundant Array of Independent Disks) enhance performance by increasing the number of hard drives used to save and access data. It helps combine multiple physical disk drives into one or more logical units for data redundancy, performance improvement, or both. Further, RAID Controllers are based on the required redundancy and performance, and the data is distributed across the drives in several ways, which are referred to as RAID levels followed by a number, i.e., RAID 0 or RAID 1. Every RAID level provides a different combination of performance, reliability, availability, and capacity.
