Colocation centers are not only used to house third-party IT equipment, but can also be utilized for disaster recovery purposes. Data centers can be costly to setup and maintain and are also limited in terms of total IT load capacity.
With colocation, a company purchases its own equipment and installs it within a facility which is operated and managed by a private vendor. The management of the facility is responsible for the security and continuous functionality of the equipment being placed there.
Over the years, there has been a surge in the demand for colocation facilities particularly because small businesses cannot afford to build expensive data centers. By opting for colocation services, small sized companies can enjoy the luxury of employing a large scale IT setup.
Companies opting for colocation for the first time have numerous questions in mind.
Method of providing power to server racks?
Server rooms within a colocation facility contain racks which are used to house servers. Since resources are shared by various clients, servers being run by two different companies can be easily positioned side by side.
Every rack provides a single conditioned power circuit which provides 110 volts at 20 Amperes. Colocation centers will also offer an alternative combination of 208 volts at 30 Ampere for some specific server arrangements. Such a combination is attached to a metered rack power distribution unit which powers approximately 20 C13 type and 4 C19 type sockets.
Overloading an electrical circuit on a rack
Colocation centers provide both managed and unmanaged services. In an unmanaged facility, companies have to ensure that circuit overload does not occur.
Every power distribution unit is fitted with a digital display that provides an ampere reading. Ideally, every rack should be running at an ampere rating which is slightly lower than the maximum threshold. If the maximum load is 30 Ampere, a rack should be consuming about 27 Ampere at the maximum.
Dual Power Racks
Some companies require server configurations that call for dual power. Under such conditions, power to both circuits is routed through different power distribution units. This allows for more redundancy and reliability within the power supply.
An entire colocation facility’s structure is based around redundancy. Redundancy is defined as the ability of an entire system to keep functioning even when some individual units fail to respond. That is why the power distribution of an IT facility is fitted with multiple backup generators. If one or two of the generators fail to work when a power outage occurs, load can be evenly distributed amongst the rest of the units.
Colocation centers are on the frontline of disaster recovery management for majority of the firms. They are a much cheaper alternative as compared to data centers and provide a high level of flexibility.
