A rack server also known as the rack-mounted server is a computer devoted to using as a server and designed to be mounted in a framework called a rack. The rack contains several mounting slots called bays, each intended to hold a hardware unit protected in place using screws. Rack servers have a low-profile attachment, in contrast to tower servers, which is built into a vertical, detached cupboard.
How Rack Servers are Useful?
A single rack can have numerous servers stacked one above the other, combining network resources and reducing the necessary floor space. The configuration of rack server also makes cabling easier among network components. In an equipment rack filled with servers, an exclusive cooling system is needed to prevent excessive heat buildup that would else occur when several power-dissipating modules are confined in a lesser space.
Rack servers are very expandable, and some of them consist of 12 or more disks right in the framework and support for four or more processors, each having multiple cores.
What Capability is Needed to Manage Rack Servers?
Rack servers often need KVM capability to be managed, though some organizations only push a monitor cart around and associate video as well as USB ports on the front of the server so that they don't have to concern about KVM.
