As detailed here, Sun Microsystems plans to introduce a new feature in early January to let its UltraSparc T1-based servers run multiple operating systems simultaneously, partly matching abilities of rival machines from IBM and Hewlett-Packard.
The technology, called logical domains, or LDoms, is the latest move in a race to make servers as flexible and efficient as possible through a general technology called virtualization. Customers using the technology will require the 11/06 update to Solaris 10, due in November, and either new hardware due in January or a firmware update to existing Sun Fire T1000 and T2000 servers, said Pradeep Parmar, product manager of business strategy for Sun’s server group.
For Sun, the LDom approach adds a third, intermediate option when it comes to sharing multiple tasks on a single machine.
