ASHRAE Committee Formed to Establish Thermal Guidelines for Datacom Facilities
Introduction The environment of every data center is complex and unique. Air currents within the data center have hot and cold air streams colliding, cold air exhausting upward from perforated tiles, hot air streams exhausting from tops and the rear of servers and storage racks. Not only are these air circulation patterns extremely complex, they can also be transient in nature … [Read more...]
Server Design Challenges for the High-heat-load Internet Data Center
Introduction Microprocessor and system thermal management are linked to facility cooling: power dissipation and cooling techniques employed at one end of the size scale have cascading impacts at the other extreme (Figure 1). For example, ineffective airflow distribution or insufficient underfloor static pressure in a data center can reduce the supply airflow rate from … [Read more...]
