UltraSPARC T2 Plus & LDoms 1.0.2

Today we announced our T5140/T5240 platforms, based around the UltraSPARC T2 Plus processor. This is the first CMT platform which supports multiple processor chips (2), providing up to 128 hardware threads of CMT goodness! And to go along with these platforms, we're releasing Logical Domains version 1.0.2, which fully supports the new T5140/T5240 systems, including the ability to create up to 128 logical domains to match the number of available hardware threads.

Of course, most users probably won't want to run 128 single threaded logical domains, but the fact that you can is a testament to the scalability of the architecture.

Other features of LDoms 1.0.2 include:

  • Support for up to 64 domains on UltraSPARC T2 based systems
  • Libvirt management interface software included
  • A slew of bug fixes

Of course, LDoms 1.0.2 supports all the platforms supported by LDoms 1.0.1 & LDoms 1.0, and like its predecessors, is available at no extra cost. In fact, LDoms 1.0.2 comes factory installed on all T5140/T5240 systems. The associated firmware & LDoms Manager packages are also available from the Sun Download Center.
