The New York Times > Technology > I.B.M. Plans to Build Servers That Act Like Mainframes "I.B.M. plans today to announce new server computers that behave more like mainframes and are priced as low as $1,500. The servers will be able to run as many as 10 operating systems on a single machine. One processor can divvy up the workload - packing the capability of several machines into one - by building several virtual machines that run on the underlying hardware. It is a technology that has existed for decades in the mainframe market long ruled by I.B.M.
...
I.B.M. asserts that its new technology promises to simplify the management of corporate data centers and improve the utilization rates of the server computers that run those data centers. Mainframes, analysts say, typically run at 80 percent of capacity on average, compared with 10 to 30 percent for servers running the Unix operating system, Windows or GNU Linux."
