"Sun's new x64 systems with Quad-Core AMD Opteron processors offer customers increased performance, scalability and energy efficiency, and ultimately more value than similar servers on the market," said Lisa Sieker, vice president of marketing, Systems Group, Sun Microsystems. "In addition to more memory, compute density and disk drives than the competition, our server innovations also enable customers to fully realize the benefits of virtualisation and energy efficiency. "
