Liquid-cooled: Introducing PRIMECENTER LC racks - Cool-safe™ for Servers

Future proof, more reliable and quieter with Fujitsu Siemens Computers new rack technology

Hanover/Germany, March 10, 2005 - 2005 – Fujitsu Siemens Computers has taken the power of water to the data center with its new liquid cooled PRIMECENTER LC racks being introduced at CeBIT. LC stands for liquid cooled, and two versions of the 19-inch server racks (38 U and 46 U models) will feature the company’s innovative Cool-safe™ for server technology. The new PRIMECENTER LC racks will be available in the second quarter of 2005.

This solution handles the increasing amounts of heat produced by servers and their subsystems and components (like CPUs and memory) much more efficiently than the traditional fan and air conditioning setup. Instead of cooling a constantly warming room, Cool-safe absorbs the heat within the system using special water-cooled heat exchangers.

The advantages to this method are numerous. Apart from the vastly superior cooling properties of water in relation to air, a much less complex infrastructure is needed, since PRIMECENTER LC racks put no additional burden on the data center’s air conditioning system. This significantly alleviates structural and spatial requirements as well as power consumption, thus decreasing overall operating expenses.

The “cool” PRIMECENTER LC racks can be safely stacked much closer together than their conventional air cooled racks, providing up to three times the server capacity in the same room. And with their IP52* rating, which quantifies the degree of resistance to dust and water, they can even be deployed in an assembly hall or other previously unthinkable places outside the data center. Additional advantages: Because the system is fully closed, PRIMECENTER LC only needs to be filled once with water under normal conditions and ambient noise levels are reduced by half, or around 10 dBA.

Building upon advancement
The new PRIMECENTER LC racks deliver all the benefits of Fujitsu Siemens Computers’ acknowledged experience in the data center. The PRIMECENTER’s modular design allows the seamless integration of heterogeneous data center assets, including PRIMERGY and PRIMEPOWER compute nodes, SAN and NAS storage subsystems, hubs, KVM switches and more, using an universal power circuit structure.

The new server technology is more reliable and lasts longer, while the greater availability gained further reduces the need for administration and servicing, lowering the total cost of ownership even more. The leading European IT provider has thus managed to again deliver innovation that drives data center efficiency while still protecting investments.
