Advantages and Disadvantages of Three-Layer Raised Computer Flooring

摘要

A traditional single-layer raised computer floor often combines three functions;routing space for low-voltage signaling cables between computer, routing space for high-voltage power cables to computers, and plenum to supply cool air to prevent computers from overheating. A three-layer raised floor separates these functions into three separate layers; the top layer houses the low voltage signal cables, the middle layer houses the high voltage power cables, and the lower layer is a sealed plenum with 'chimneys' to supply cool air where required.
