* A common arrangement for the perforated tiles and the data communications equipment. Supply air is introduced into a region called the cold aisle
* On each side of the cold aisle, equipment racks are placed with their intake sides facing the cold aisle. A hot aisle is the region between the backs of two rows of racks
* The cooling air delivered is drawn into the intake side of the racks. This air heats up inside the racks and is exhausted from the back of the racks into the hot aisle
A common means of providing cooling to data communications rooms in which IT equipment is arranged in rows and cold supply air is supplied to the cold aisle, pulled through the inlets of the IT equipment, and exhausted to a hot aisle to minimize recirculation of the hot exhaust air with the cold supply air
An air distribution system that is used by some long-distance carriers in North America. This system introduces the supply air horizontally above the cold aisles and is generally utilized in raised-floor environments where the raised floor is used for cabling
An air distribution system used predominantly in telecommunications central offices in Europe and Asia. Typically, this system introduces air horizontally from one end of a cold aisle
Executive group within HPG. Currently, HPG and HPSC are the same (i.e., all HPG members are part of HPSC)
One of several groups within the SPEC organization. HPG has created the benchmark suite SPEChpc96, aiming at high-end machines including both shared-memory and distributed-memory architectures
Includes scientific workstations, supercomputer systems, high speed networks, special purpose and experimental systems, the new generation of large-scale parallel systems, and application and systems software with all components well integrated and linked over a high speed network
These filters are designed to remove 99.97% or more of all airborne pollutants 0.3 microns or larger from the air that passes through the filter. There are different levels of cleanliness, and some HEPA filters are designed for even higher removal efficiencies and/or removal of smaller particles
