Page 5 - Active Cool fans; servers to properly cool the server blades within the enclosure.
Active Cool fans Quite often, dense, full-featured, small form-factor servers use very small fans designed to provide localized cooling in the specific areas needed by the server blade. Because such fans generate fairly low airflow (in cubic feet per minute, or CFM) at medium backpressure, a single ...

HP PARSEC architecture HP Parallel Redundant Scalable Enclosure Cooling (PARSEC) architecture is a hybrid model for cooling that combines the best of local and centralized cooling in a single system to ensure optimum airflow and cooling for all servers. Density, once a barrier to cooling, is turned ...
