Virtual to the Core of the Sun

Arthur Cole

That chip-makers are embedding virtualization tools directly onto new silicon is no secret. But Government Computer News has an interesting write-up here about how Sun Microsystems's Logical Domains technology will bring virtualization down to the processing core.


Unlike the company's Containers approach, Logical Domains can create a virtual environment on an individual thread. That means a single eight-core UltraSparc T2 that can run eight threads per core is capable of maintaining 64 virtual entities.


LDoms, as it is called, is available on the OpenSolaris 10 and Solaris 10 systems. Using its own operating system kernel, it interacts directly with hardware and other domains, which keeps the pressure off the CPU during peak loads and also adds a measure of flexibility when managing system resources.


Sun has a knack for bringing cutting-edge technologies together. With individual cores now capable of running multiple systems, enterprises will soon be able to offer virtual environments to suit just about any need.

Cool info will lead to a lot of cost cutting and reduce TCO of call centres. Reply
