What is a rack server?

If you want to know what is a rack server and how it can benefit your business. Then, this comprehensive article is for you.

One of the most practical pieces of IT gear is the rack server, which enables you to store several servers in a compact rack structure. Server modules are kept in mounting slots known as bays, which can typically house one to eight server units. Server racks have a lower profile than tower racks and allow your servers to sit on a shelf, keeping them off the ground. Tower racks are made to be held in cabinets.

Rack servers are helpful because of their adaptability, which enables them to be extended, stacked, and—possibly most significantly—networked. Rack servers update your data center by providing performance, reliability, and scalability for the primary, mission-critical tasks between businesses.

In this blog post, we’ll go through how a rack server operates, the features of a rack server, components, and its uses.

What is a rack server

The server rack is also known as a rack mount server, rack-mounted server, or rack mount computer. It is a rectangular building that is used to house servers.

The server rack’s benefits include better space conservation, increased scalability, maximized airflow when used with a cooling system, ease of routine computer maintenance, and diagnostics due to their design. In addition, it enables technicians and operators to quickly slide rack servers into and out of them.

What is a rack server used for?

Rack servers offer clients data and particular services as all servers do. As a result, it is used in data centers with dozens or hundreds of server racks and server rack cabinets.

Rugged rack servers are mostly seen supporting commercial and military applications in the field.

MIL-STD-810H, MIL-STD-461, CE, FCC, or DO-160 are certified to military and industrial standards. These dependable, powerful machines have undergone stress testing to ensure they can survive challenging climatic conditions, including extremely high or low temperatures, vibration during transit or operation, and humidity in locations where atmospheric moisture is common.

In military programs, rack servers can often be found inside compact and sturdy MIL-STD-810-certified rack server cases or supporting an embedded computing application.

What Are the Components of a Rack Server?

Even though the capacity of each of these parts might vary significantly based on your compute and data needs, the majority of single rack servers come with the following standard components:

1. Motherboard

This single server board connects all the systems in your rack and allows the components and data buses to communicate.

2. Central Processing Unit (CPU)

Also known as a processor, the CPU enables you to program processes and send commands to the servers in your server rack. Imagine it as the thoughts that pass through the computer’s head.

3. RAM (Random Access Memory)

Your server stack’s operational data processing capacity. Add more server units to scale it up or remove branches to scale it down. However, you can easily enhance your processing power in the future without time-consuming reconfigurations if you choose server racks with the most server memory slots.

4. Host-Bus Adapter (HBA)

This simple component enables you to link external devices, like networked storage, to your server.

5. I/O Ports

These ports are a separate subcategory, and where you put them can significantly impact the look and feel of your server. Types of ports include USCs, serial ports, or AUX ports. The ones you pick will depend on your server’s configuration, use case, and size.

6. Drive bays

All server rack configurations have extra drive bays. As your complexity increases, you can add more solid-state drives (SSDs) or hard disc drives (HDDs).

7. Extra equipment

These small add-ons make it simpler to manage your server stack. Rack rails, cable management bars, and a cooling system are all standard components that maintain your server rack.

Benefits of Rack servers

Rack servers are the workhorses of the IT world, used in companies of all sizes. And that’s not surprising. Rack servers can offer you many clear advantages over other server configurations, including:

1. Consolidated server and network control:

Every rack server has a network interface, and it is simple to install a network switch within the rack cabinet and link all of the servers to it.

2. Expandable

The addition of new servers or updates is simple. There is plenty of room to add additional servers or perform upgrades if your activities grow. In addition, your company can maximize uptime by using hot-swappable devices, which you can remove without shutting off the system power.

3. Convenience

The technician slides the server along the rails to add or remove a rackmount server. Keep in mind that larger servers (4U and 5U) will weigh more and require more cooling. Additionally, since all your servers may be stacked horizontally onto one or more racks, they occupy little room in the data center.

4. Compact

Each rack server fits neatly into a 19-inch by 1.75-inch enclosure. Each of those 1.75-inch-high rack units is abbreviated as U, with a typical full-size rack cage being 42U, and hardware typically measured in heights of 1U, 2U, 3U, and 4U.

Blade servers do not have minimum size limits, unlike conventional rack servers. As a result, blade servers can fit in small, confined locations and function effectively with other streamlined servers as part of a more significant overall structure.

Uses of Rack servers

Your IT department can organize, safeguard, and store your data processing resources using rack servers. Your business can build a scalable and manageable network when you mount your server units onto a rack server. Numerous rack servers are commonplace in industries. To keep data operations running smoothly, some companies might have hundreds or more servers connected to the same corporate network.

The majority of rack servers are stationary and made from metal. In contrast, rack servers are created for military establishments to be mobile for use in the field. These servers come with carrying cases, dust-proof shields, mobile cooling equipment, rubberized bumpers, and other design features that enable them to keep their server systems mobile.

Now that you know what is a rack server, choosing your rack server’s configuration is a crucial IT management choice. Choose carefully!
