Hot aisle temperature in Class A data center rooms
ASHRAE recommends keeping server rooms between 64. Although ventilation and air-recycling systems offer many ways to achieve this temperature range, one of the most efficient and cost-effective methods is aisle containment. rategies orient the IT racks in what is called a hot aisle/cold aisle layout. Cold aisles are ormed by the space between the front faces of two rows of IT equipment rac. Maintaining the proper temperature and humidity levels in a data center is critical for any organization with an on-premises IT. This document initially develops a list of generalized thermal best-practice recommendations as a first step towards temperature management and measurements in data centers, ultimately saving infrastructure energy as well as protecting the electronic equipment.
