A company called Rackable, a server solutions provider, is now offering green (low-power, low-emi) systems featuring Opteron or Xeon dual-core CPUs. With their C2002 High Efficiency Series, they use straight DC power, passive heatsinks and are designed to be used in large numbers but still be easy on the environment. They are also pushing a new rackmount low end server, nothing fancy but useful, using two separate systems inside a single chassis. The catch, though, is that ScaleMP, 3rd-part vendor software, is employed to let both computers, along with other ones added over time, to run the same operating system with shared memory. Despite this company being a bit player, the offering is still pretty hot at $69,000. Virtualization is a great way to go, though, and Rackable is apparently doing pretty well.
