  • data center chiller

    A data center chiller is a cooling system used in a data center to remove heat from one element and deposit it into another element. Chillers are used by industrial facilities to cool the water used in their heating, ventilation and air-conditioning (HVAC) units. (Continued...)

  • data center evaporative cooling (swamp cooling)

    Evaporative cooling, also known as swamp cooling, is a strategy for cooling air that takes advantage of the drop in temperature that occurs when water that's exposed to moving air begins to change to gas. You've probably experienced the effects of evaporative cooling if you've ever changed out of wet clothes because you felt chilled.

  • Data Center Infrastructure Efficiency (DCiE)

    Data Center Infrastructure Efficiency (DCiE) is a metric used to determine the energy efficiency of a data center. The metric, which is expressed as a percentage, is calculated by dividing IT equipment power by total facility power.

  • data center resiliency

    Data center resiliency is the ability of a server, network, storage system, or an entire data center, to continue operating even when there has been an equipment failure, power outage or other disruption.

  • data center services

    Data center services is a collective term for the supporting components necessary for the proper operation of a repository for storage, management and dissemination of data organized around a body of knowledge or pertaining to an enterprise... (Continued)
