Modular data centers typically come in two types of form factors. The more common type, referred to as
containerized data centers or
portable modular data centers, fits data center equipment (servers, storage and networking equipment) into a
standard shipping container, which is then transported to a desired location. Containerized data centers typically come outfitted with their own cooling systems. Cisco makes an example of this type of data center, called the Cisco Containerized Data Center. Another form of modular data center fits data center equipment into a facility composed of prefabricated components that can be quickly built on a site and added to as capacity is needed. For example, HP's version of this type of modular data center is constructed of sheet metal components that are formed into four data center halls linked by a central operating building. In 2012,
Compass Datacenters, LLC filed and was later granted a patent for a "Truly
modular building datacenter facility." ==Examples==
