RACKABLE SYSTEMS ANNOUNCES DAY ONE SUPPORT OF NEW QUAD-CORE AMD OPTERON™ PROCESSORS

Company Leverages Power-Efficient Quad-Core AMD Opteron Processors in Eco-Logical™ Data Center Servers

FREMONT, Calif., -- 11/13/2008 -- Rackable Systems, Inc. (NASDAQ: RACK), a leading provider of servers and storage products for large-scale data centers, today announced the immediate availability of servers based on the new Quad-Core AMD Opteron™ processors (codenamed “Shanghai”). Select Rackable Systems server models will leverage the new 45nm Quad-Core AMD Opteron processors to help increase energy efficiency and further improve performance on server and workstation application workloads that matter most to customers.

“The new generation of Quad-Core AMD Opteron processors once again raises the bar for price-performance-per-watt in an existing data center footprint, compared to previous generations of AMD Opteron processors,” said Giovanni Coglitore, chief technology officer at Rackable Systems. “AMD continues to integrate intelligent, energy-saving technologies like Enhanced AMD PowerNow!™ technology and AMD CoolCore™ technology into their processors. When coupled with our most energy-efficient server designs to date, we can help reduce overall power consumption during non-peak workloads and enable lower the total operational cost in our customers’ datacenters.”

Beyond having four cores, Quad-Core AMD Opteron processors feature Direct Connect Architecture which uses high bandwidth interconnect links that allow processors to connect directly with others in the configuration, the I/O subsystem, and the main memory banks helping reduce bottlenecks inherent in traditional front-side bus architectures. Combined with Rackable Systems’ industry-leading energy efficient server and storage designs, the new Quad-Core AMD Opteron processors is expected to further increase AMD’s performance-per-watt leadership.

“AMD and Rackable Systems have a long history of delivering innovative and energy efficient technology to directly address customer demand for added performance within an existing infrastructure,” said Patrick Patla, vice president and general manager, Server and Workstation division, AMD (NYSE: AMD). “Our newest Quad-Core AMD Opteron processors, with enhanced performance-per-watt capabilities, helps enable lower power consumption in Rackable Systems’ customers’ while providing optimal performance in critical workloads such as web serving and high-performance computing.”

Ideal for applications ranging from cloud computing to High Performance Computing, and in industries including financial services, oil and gas, and entertainment, Rackable Systems’ broad range of server and storage products feature easier serviceability, maximum density and greater thermal efficiency to reduce overall operational expenditures.
