SGI (NASDAQ:SGI), a trusted leader in technical computing, today announced that a single SGI® Rackable? C2005-TY6 server achieved a world record for performance-per-watt on the SPECpower®_ssj2008 benchmark, an industry-standard measurement of energy efficiency of volume server class and multi-node class computers. C2005-TY6 server easily outperformed comparable systems from Dell, IBM and HP.

C2005-TY6 outperformed its nearest competitors in two important areas, including power at 100 percent load (watts), and the overall performance-per-watt metric (ssj_ops/watt). Complete SPECpower®_ssj2008 results are posted at www.spec.org.

A single SGI Rackable half-depth C2005-TY6 server beat Dell, IBM and HP with the lowest power of only 226 watts at 100 percent load and the highest performance-per-watt of 3,077 ssj_ops/watt.

?C2005-TY6 server's unprecedented energy efficiency directly translates into meaningful business benefits for data centers,? said Conor Malone, vice president of engineering at SGI. ?The breakthrough SPECpower_ssj2008 results prove that SGI Rackable half-depth servers continue to lead in power and cooling efficiency by having the flexibility to incorporate best of breed components from partners like Intel.?

The tested C2005-TY6 server was powered by a total of two six-core Intel® Xeon® 5670 processors, 12 GB memory, one Intel® 32 GB SLC flash drive, Microsoft® Windows 2008 R2 Server Enterprise Edition operating system, and ran six instances of IBM J9 Java Virtual Machine (JVM).

?We are delighted that SGI has chosen the Intel® Server Board S5500WB for its Rackable system,? said Lisa Graff, vice president and general manager of the Enterprise Platforms & Services Division at Intel. ?Intel strives to design world-class server building blocks to help customers like SGI achieve world-record results.?

The C2005-TY6 half-depth rackmount server, which will be available in March 2011, has the following notable power efficiency features:

  • Intel Server Board S5500WB optimized for performance-per-watt by incorporating spread-core processor/memory layout, high efficiency VR's, comprehensive temperature monitoring, and extensive characterization and tuning across hardware and software;
  • Flash-enabled technology that reduces overall power consumption up to a factor of eight compared to 2.5-inch and 3.5-inch HDDs;
  • Support for low-voltage processors from Intel that run at the same clock rates as their higher-voltage counterparts but consume less energy;
  • P-states and C-states that allow the CPU frequency and power to dynamically change based on the workload;
  • Support by SGI Management Center which, on servers with Intel® Intelligent Power Node Manager, provides power and thermal monitoring and policy based power management;
  • CPUs and DIMMs that support active power management that allows for significant power savings at idle and moderate loads, but can run at peak frequency when needed;
  • Unused memory channels that can be dynamically placed into a low power state;
  • Option of disabling unused serial, USB and Ethernet ports.
