Blade servers improve cooling management


Blade servers improve cooling management

Emerson Network Power, a business-critical continuity supplier, and Egenera, a leader in utility computing, have introduced the CoolFrame solution, which integrates Emerson's Liebert XD cooling technology with the Egenera BladeFrame EX system.

CoolFrame allows users to deploy Egenera servers while adding, claim the companies, virtually no heat to their facilities. This represents the first time Liebert XD technology has been used to deliver cooling directly to a server rack.

The two companies are confident that adding CoolFrame to a BladeFrame EX reduces the heat dissipation of the rack to the room from as much as 20,000 watts to a maximum of 1,500 watts without impacting the performance of the 12 processor cores per square foot.

The claimed bottom line result of this is greatly reduced energy costs for datacentre cooling of a BladeFrame EX environment by eliminating 1.5 kW of fan load per rack from the room cooling system. At full capacity, say the companies, this equates to a 23% reduction in datacentre cooling energy costs. At reduced loads the savings percentage is even higher, the two firms claim.

"Solving datacentre cooling issues effectively and efficiently requires server manufacturers and power and cooling specialists to work together to bring cooling closer to processing resources to increase cooling capacity and flexibility," says Bob Bauer, group vice-president of Emerson and president of Liebert Worldwide.

The Liebert XD is a waterless cooling solution that delivers focused cooling through an infrastructure that includes a pumping unit or chiller and overhead piping system with quick-connect fixtures. Flexible piping connects Liebert XD cooling modules to the infrastructure, simplifying the addition of modules or system reconfiguration.
