Collocation refers to the provision of space of telecommunications equipment on a service provider’s collocation centre. The colocation facilities allow web masters to have full control and access to their site, and are particularly suitable for small and medium sized businesses.


Rack Servers

It is the situation when the server is mounted in a rack. A rack is the metal framework that holds electronic equipment and usually contains bays. The size of colocation facilities and servers is variable, server racks have a finite amount of space available. It is measured by “rack unit”. The standard size of a rack mount server is 1 U or 1 rack Unit. 1U is equal to 4.45 cm or1.75 inches. This is the unit of measurement for defining the vertical space within a colocation facility. A 2U server takes double the amount of space of a1U server, just as a 4U server would take the space of 4 by 1U servers. Rack mount servers come in several sizes depending on the manufacturer and the hardware contained within. The higher the rack unit the more space accessible and the more a collocations customer can expect to pay.
