Rackable Granted Power Patent

MILPITAS, Calif. -- Rackable Systems, Inc. (NASDAQ:RACK - News), a leading provider of servers and storage products for large-scale data centers, today announced that the United States Patent and Trademark Office (USPTO) awarded the company patent number 7,173,821, entitled "Computer rack with power distribution system." This patent awards protection to Rackable Systems for certain aspects of its innovative cabinet, power and server designs, which optimize density, energy efficiency and thermal management in the data center.

The patented designs, released in 2003, leverage step-down power converters and alternating current (AC) to direct current (DC) power converters -- commonly known as rectifiers -- to distribute DC power to systems inside a server cabinet. Failover protection may be achieved by replacing a standard AC power supply with a highly reliable DC power card. Additionally, a secondary voltage step-down may be used within each system. This novel method of power distribution may occur inside or outside of the server cabinet, allowing for the flexibility to provide DC power to either a single cabinet or entire row of cabinets populated with systems.
