Server HardwareThe Server ComputerThe hardware of a server computer is very similar to that found in common client computers. However, server computers are designed to perform complex functions using high-quality computing components. These components include motherboard, processor, network connection, memory, hard drive, power supply, and video adapter. The main electrical circuit of the computer is located on the motherboard. Other key components present in the motherboard include CPU, chipset, graphics adapter, standard IDE hardware controller, network interface, I/O ports, expansion slots and memory. The processor, on the other hand, is the brain behind the computer. Computer processors are designed to run on servers created specifically for this purpose. Intel is a leading manufacturer of computer processors; examples of Intel server processors include Xeon, Pentium D, and Itanium 2. These processors feature high clock speeds with one or more processor cores. Server computer processors are generally very powerful to allow them to undertake complex processes. The network connection is a key component of server computers; Most servers come with motherboards that come with network adapters. Server Upgrade Today's servers are designed to last for longer periods; however, the idea of ​​keeping up with new data center needs requires constant hardware upgrades. The main reasons to undertake server upgrade include; need to extend server life, need to get the most out of existing servers, need to use old data center hardware, and implications of virtualization. Server virtualization is a fundamental network function because it makes one server act like many servers; each with unique applications and operations… middle of paper… infrastructure, cloud-ready, software-defined and workload optimization. One of the next-generation servers is HP ProLiant Generation 9, designed to deliver benefits such as increased processing capacity, improving application workload performance, and ensuring rapid service delivery for better business outcomes. The other feature of this server included a 40GB Ethernet, which includes both the LAN on the motherboard and network interface card adapters for blade and rack servers. The memory upgrade from the 8th generation servers represents a leap from DDR3 memory and clock speeds of 1866 MHz to a system that supports DDR4 memory with optimal clock speeds reaching 2133 MHz. HP Generation 9 servers will be the first line of HP servers that have UEFI Secure Boot. With this new security feature, a cryptographically signed image of an operating system is used to boot the system.
