Data center facilities Definitions

  • F

    free cooling

    Free cooling is when ambient air or water is used to cool data center space and equipment.

  • fuel cell

    A fuel cell is an electrochemical cell that derives its energy from combustible substances such as hydrogen, methane, propane, methanol, diesel fuel or even gasoline... (Continued)

  • G

    green data center

    A green data center is a repository for the storage, management, and dissemination of data in which the mechanical, lighting, electrical and computer systems are designed for maximum energy efficiency and minimum environmental impact... (Continued)

  • H

    Hot spot/cold spot

    A hot spot/cold spot is an undesirable tightly-focused local temperature variation which often occurs when data center equipment is improperly cooled.

  • hydrofluorocarbon (HFC) clean agent

    Data centers and telecom rooms use hydrofluorocarbon (HFC) clean agent systems for fire protection to avoid damaging electrical and electronic equipment.

  • I

    intelligent power management (IPM)

    Intelligent Power Management (IPM) is a combination of hardware and software that optimizes the distribution and use of electrical power in computer systems and data centers. While the installation of IPM involves up-front cost and ongoing maintenance, the technology can save money in the long term as a result of reduced electric bills, reduced downtime and prolonged hardware life...

  • K

    Kyoto cooling (Kyoto wheel)

    KyotoCooling is an energy-efficient free cooling system for data centers. Kyoto cooling uses outside air to remove the heat created by computing equipment instead of using mechanical refrigeration.

  • L

    limited combustible cable (LCC)

    Limited combustible cable (LCC), also called CMP-50 cable, is fire-resistant cable with insulation made of a synthetic material called fluorinated ethylene propylene (FEP).

  • load bank

    A load bank is a device that generates a prescribed amount of electricity draw to test the reliability of electrical switching, generator output, uninterruptable power supply (UPS) systems and cooling in a data center.

  • load shedding

    Load shedding is a reduction of power demand by a utility provider during peak or stressed times. Participants voluntarily reduce demand for utility power and rely on secondary sources for uninterrupted operation, or lower or lose power supply in an involuntary load shedding event.

  • M

    mainframe (big iron)

    A mainframe (also known as 'big iron') is a high-performance computer used for large-scale computing purposes that require greater availability and security than a smaller-scale machine can offer... (Continued)

  • mechanical refrigeration

    Mechanical refrigeration, often referred to simply as refrigeration, is a process by which heat is removed from a location using a man-made heat-exchange system.

  • O

    Open Blueprint

    Open Blueprint is IBM's strategic view of the network computing services and the relationship between these services.

  • Open Compute Project

    The Open Compute Project is an initiative started by Facebook to share efficient server and data center designs with the general IT industry.

  • Open Rack

    The Open Rack specification is an open standard for server racks designed to integrate with other parts of Facebook's Open Compute Project (OCP).
