Servers

In this section you will read about :

1. How do servers work/function?

2. What are the benefits of servers?

3. What are the various types of servers?

Servers are capable of storing and processing thousands of websites every minute. Therefore, they require specialized technology and a unique build structure to carry out such complicated tasks.

Unlike traditional desktops that use a single hard drive for delivery and storage, servers use RAID. Redundant Array of Inexpensive Disks or RAID refers to the data storage virtualization technology that functions simultaneously with multiple hard drives. It combines the physical disk drive components to minimize data redundancy and improve performance.

In a nutshell, the server function with:

• Redundant Array of Inexpensive Disks storage
• RAM to provide speed for meeting more requests
• CPU that ensures that all tasks are appropriately allocated to the correct location and proceeding as per the planning

Servers perform various functionalities like sharing resources or data among multiple clients, performing computations, etc. Depending on your requirement, the servers can be pretty expensive. But are these servers worth your time and money? Of course, because:

• Scalability is one of the primary reasons why companies invest in high-end services. These are specifically designed for connecting multiple devices and access resources to scale up as per your company's growth.
• Dependability as servers come with higher-grade components and in-built redundancy that can lower downtime even when a part fails.
• Initially, it might be an expensive investment that can eventually help one to save money in the future. Since the server will be responsible for bulk processing, storing, and managing multiple devices, the work efficiency increases.
• Excellent online and offline support are available with servers as they run software systems and other services for larger audiences with easy configurations.
• Servers make collaboration easier. Multiple files and data are stored on these servers that can offer access to everyone. So, people from different teams can work on the same project simultaneously by accessing these files directly from the servers.
• Servers always leave room for improvement and expansion. They might not be very powerful like PCs, but high-end ones allow multiple CPUs and RAM slots to accommodate perfectly, delivering excellent performance.

Depending on their functions, shape, software, and hardware, different types of servers are available. Depending on the hardware, servers are available in:

• Tower Servers

The tower servers resemble the tower-style PC. It resides in the standalone cabinet upright position and provides easier cooling, possibly due to the low component density. These are highly affordable and ideal for small businesses on a strict budget. However, they tend to take up more space than other server types.

• Rack Servers

As the name suggests, the servers are organized in racks and can be configured to offer assistance to a wide range of requirements. Since it remains enclosed in the rack cabinet for security, it is named a rack server. These are widely popular for being highly economical and can be accommodated within smaller computer closets.

• Blade Servers

These are the compact devices that house various thin, modular circuit boards that are known as server blades. Each blade consists of a single server assigned to a particular application. Being highly dedicated, these servers are ideal for large-scale businesses as the admins have greater control over the data and its transference among other devices. Some of the benefits of using these servers include low-power use, minimal wiring, and storage consolidation.

• HCI Systems

Hyper-converged infrastructure systems are known for offering simpler alternatives to conventional IT infrastructure. The implementation processes are mainly automated and help with quick hypervisor deployment and software-defined storage implementation.

• Mainframes

Client-server architectures were introduced in the 1990s, but they still exist in the market now. They are capable enough to support huge volumes of simultaneous transactions and heavy I/O loads without compromising performance. Primarily prevalent in financial service firms, these servers can help deal with real-time transactions. However, these are expensive and bulky in size.
