Qimonda Helps Reduce Data Center Energy Costs - Servers Equipped With Qimonda's Power Saving Memory Modules Show up to 30% Reduction in Power Use

Spiraling energy costs are becoming a serious issue in data centers, which are installations of hundreds or even thousands of servers and associated equipment used by Web services companies and operating computer networks of large organizations. Qimonda and Sun are working closely together to provide low power products and set industry benchmarks for power saving performance in server applications. Reduction in power saves energy costs in two ways, directly by reducing the energy used by the server and indirectly by reducing heat that must be managed by cooling systems.

Tests showed up to a 30% reduction in memory power consumption when combining Qimonda's power efficient DDR2 Dual In-line Memory Modules with Sun.s breakthrough server system designs, demonstrated by platforms such as the award winning Sun Microsystems Sun Fire T2000 server. Based on an analysis of costs to power a typical data center described at a recent industry conference, memory modules from Qimonda can save up to $70,000 per year in energy costs.

The data Qimonda used for this calculation was presented at a conference hosted by Sun Microsystems in January of this year in Santa Clara, Calif. At the same conference, industry experts forecast that by 2008 computer memory subsystems will represent up to one-half of the power used in computer servers.

"Sun and Qimonda have a clear focus on and roadmaps for lower power products for the future," said Kurt Doelling, Vice President for Worldwide Operations of Sun Microsystems. "The challenge of managing the energy budget of data centers must be addressed across the entire system design, and Qimonda is making a significant contribution by proving that its DIMMs deliver energy savings."

"Qimonda's power saving trench technology reduces server's energy consumption significantly and at the same time enables server systems to incorporate higher densities and maximize system performance," said Thomas Seifert, member of management board of Qimonda. "Thus we are best positioned to provide a clear cost advantage for server systems as infrastructure demand grows rapidly and energy costs start to exceed equipment costs."

Qimonda compared the energy used by both its 1GB DDR2 DIMM and 2GB DDR2 DIMM products to 1GB-density DDR2 DIMM devices from other companies. At the same 1GB density, the operating current consumed by the Qimonda components was up to 30 percent lower. When Qimonda tested its 2GB DIMMs, operating current was equal to or slightly less than the 1GB density products from other companies.
