The evolution of cloud computing platforms has introduced virtualisation, which significantly changes the role of servers for various businesses. Virtualisation refers to a virtual version of computer hardware, storage devices, or networks that helps optimise the use of resources. It also makes it effortless for multiple operating systems or applications to run seamlessly on a single physical machine.
This arrangement allows efficient management, scope to scale, and flexibility in IT infrastructure deployment. This alternative also enables businesses to maintain in-house servers and private clouds so that sensitive data and applications can be used. Because of these benefits, servers have become a popular choice.
Let’s learn about server hardware that is extremely popular in the corporate world.
Exploring the Most Popular Types of Servers
However, the roots of the original mainframe servers lie in the 1950s and 1960s. But the modernised version appeared in the 1990s with web and rack-mounted servers. At present, a range of servers is available, which can fit anywhere from small businesses to large enterprises.
Let’s discover their types.
1. Tower Servers
This type of server is housed in a vertical independent cabinet, which appears like a towered PC. Installing it is advantageous because it comes with simpler cooling due to lower component density. Considering the cost, small businesses can easily afford it for being inexpensive, though it occupies more physical space.
2. Rack Server
The rack server can be modified to best fit in a server rack within a data center. It is typically deployed to cater to many computer functions and manage diverse workloads. If you compare it with tower servers, it takes up less space. It is available in a standardised size, making it easy to install and replace. The only challenge is managing its cables because it is connected to tethered power supplies, networking objects, and storage devices.
3. Blade Servers
This server appears to be a compact device with several thin and modular circuit boards (also known as server blades). Each blade on a single server is typically dedicated to a specific application. It comes with excellent processing density and features like reduced wiring and low power consumption.
Considering its benefits, it has features like individual blade cooling, reduced wiring, low power consumption, and optimised storage capacity. It is hot-swappable, and modular components are easy to repair. The only risk with it is its dependency on vendors because they are installed in their architectures. They may lock it up for buyers at any time.
4. Hyperconverged infrastructure, or HCI
HCI systems provide a highly optimised alternative to conventional IT environments. This infrastructure allows a mid-level data centre engineer to conduct the hardware setup. Deploying the hypervisor and software-defined storage within just an hour. However, setup wizards guide it to be completed. Majorly, its implementation occurs automatically, which simplifies its installation and management.
However, the client-server architecture was foreseen to eliminate mainframes. But they survived. Now, their advanced version is available, with the capacity to handle extensive simultaneous transactions and heavy input and output loads. This happens smoothly without compromising the performance. That’s why financial services providers find it ideal to handle concurrent and real-time transactions. Unfortunately, they are extremely pricey and spacious.
Key Requirements for Installing a Server
To discover the requirements, an IT buyer must think of various factors. These factors are related to current and future workloads. Though every organisation has its own set of requirements, the following key server hardware features must be priorities.
1. Processor Power (CPU)
Before making any decision, consider the role of the CPU in executing any program and data manipulation. Simply put, discover the number of cores, CPU clock speed, cache size, and the count of sockets. This discovery guides you to learn that servers can have single or multiple processors. The IT engineer must finalise a server hardware configuration that proves the best fit with the requirements of the organisation. Let’s say an organisation uses cloud infrastructure in a data centre. It enables the organisation to handle multiple computing tasks using a 0.5U single-CPU server or a 1U dual-CPU server.
2. Optimizing Memory (RAM)
Optimising server memory is a must-have need to maximise system performance. With greater available memory, enhancing a heavy workload with efficiency is like a walkover. In addition, an IT buyer should prioritise features like fault tolerance and error-correcting code to ensure reliability.
3. Storage Capacity
The storage capacity of a server depends on the intended applications and workloads. If you compare the requirements of a database server with those of a web application server, there will be a big difference in their needs. Whether you use SSDs or traditional hard drives, the specific server workload enables you to discover compatible technologies, such as SCSI, serial advanced technology attachment, or non-volatile memory express (NVMe). For the need of BPM companies that cover large & unstructured databases, local instance drives, such as NVMe PCI Express units, are helpful. Considering other factors, drive speeds and disc space are significant.
4. Establishing Connectivity
The storage capacity of a server depends on the intended applications. No matter what you use, SSDs or traditional hard drives, the specific server workload guides you to identify the most compatible technologies, like NVMe or SCSI. This choice should be based on factors like the speed and quantity of Ethernet connectors, USB port types, and support availability.
Some other key features that should be assessed are the ability to hot-swap and redundancy for hard drives, power supplies, fans, etc. In all these arrangements, server management capacities and security features are vital. Moreover, administrators should measure the operating capacity of the server, optimal temperature, and humidity levels, which can lead to energy and cost savings.
Server Management and Maintenance
Server management requires a series of tools and proactive initiatives to extend the life of the hardware.
- Monitoring Systems: The monitoring system collects and provides access to critical data that guides administrators about potential flaws for fixing.
- Capacity Management: This is an efficiency evaluator, which provides insights into how much CPU, memory, and storage is used.
- Energy Consumption Tools: The next one is an energy consumption tool, which helps in discovering the efficiency of a server. It can be meters installed for continuous power supplies. They can also help in reporting how much power the connected devices are consuming. External power meters can be used for this purpose, which can help in analysing energy consumption online.
Important Note: Though hardware outages cannot be reversed, a maintenance provider or IT support provider can help in mitigating the problem associated with power, temperature, and memory so that premature breakdown can be discovered & prevented.
For terminating the use of a mainframe server, multiple key steps are defined. First, IT managers should list the applications on the mainframe. Then, they have the option to either outsource them to specialised service providers or migrate them to x86 servers. Additionally, there should be a proven security plan that can potentially involve the deletion of data or the destruction of the hard drive.
Conclusion
Server and network support providers or specialists have real-time experience working with servers and their maintenance. Mostly, they are aware of different types of servers and the best practices to maintain them, understanding their requirements. This guide helps them understand the different types of servers and the associated requirements required to maintain a high-performance IT environment.
