Probability that a data center system will be operable throughout its mission duration (only takes into account the effects of failure of the data center)

The data center industry and DOE partnered to develop the Data Center Energy Practitioner (DCEP) Program. The DCEP training program certifies energy practitioners qualified to evaluate the energy status and efficiency opportunities in data centers. More information at https://datacenters.lbl.gov/dcep

Probability that a data center will be operable at a future time (takes into account the effects of failure and repair/maintenance of the data center)

A building or portion of a building whose primary function is to house a computer room and its support areas. Data centers typically contain high-end servers and storage products with mission-critical functions

Commonly used to measure the rate of air flow in systems that move air

A group of connection points, often wall- or rack-mounted in a wiring closet, used to mechanically terminate and interconnect twisted-pair building wiring

Cyclic redundancy check

SPEC uses often to mean applications that are primarily bound by the available processing power. Typically, these spend most of their time performing calculations, comparisons, or transformations and do little or no I/O and spend very little time in the operating system

CPU95 is an earlier version of the CPU component benchmark suite from SPEC, which replaced CPU92 and the even older CPU89. This suite has in turn been replaced by CPU2000

CPU92 is a now outdated CPU component benchmark suite from SPEC. This was replaced by CPU95
