Volume 171, Issue 5
It was the case that customers with a mixture of T2, T2+, T3 and T4 systems could not freely move domains between systems. That is, before the release of Oracle VM Server for SPARC 2.2, the advent of which now enables migrations running domains between T-series servers with different chip types and clock frequencies. Jeff Savit contends in his post that this release enhances operational flexibility and lets domain migration be used in a wider set of use-cases.
