The process of ensuring that systems are designed, installed, functionally tested, and capable of being operated and maintained to perform in conformity with the design intent. It begins with planning and includes design, construction, start-up, acceptance, and training, and can be applied throughout the life of the building
Cold plates are typically aluminum or copper plates of metal that are mounted to electronic components. Cold plates can have various liquids circulating within their channels. Typically, a plate with cooling passages through which liquid flows to remove the heat from the electronic component to which it is attached
See hot aisle/cold aisle
The ratio of the rate of heat removal to the rate of energy input in consistent units for a complete cooling system or factory-assembled equipment as tested under a nationally recognized standard or designated operating conditions
This technology draws considerably less power than bipolar semiconductor technology in standby mode, and so it replaced many of the digital bipolar applications around the early 1990s
Two or more interconnected servers that can access a common storage pool. Clustering prevents the failure of a single file server from denying access to data and adds computing power to the network for large numbers of users
A server system that can operate independently, but has some interdependence with another server system
* Class A: Fires involving ordinary combustibles such as paper, wood, or cloth
* Class B: Fires involving burning liquids
* Class C: Fires involving any fuel and occurring in or on energized electrical equipment
* Class D: Fires involving combustible metals (such as magnesium)
Identifies the actual microprocessor, the physical package, containing one or more cores
A type of air conditioning system that has no refrigerant in the unit itself. The refrigerant is contained in a chiller, which is located remotely. The chiller cools water, which is piped to the air conditioner to cool the space. An air or process conditioning system containing chiller(s), water pump(s), a water piping distribution system, chilled-water cooling coil(s), and associated controls. The refrigerant cycle is contained in a remotely located water chiller. The chiller cools the water, which is pumped through the piping system to the cooling coils.
