Also native to the new Xeon 7300 chips is Intel's attempt to make a series of chipsets socket compatible. Dubbed "VT FlexMigration," the design will make the Xeon 7300 series consistent with Intel's other multi-processor chips through at least its next-generation 45-nanometer process core micro-architecture, code-named Nehalem, which is expected in late 2008.
"With FlexMigration, if you are going to be buying servers over a period of time, you can add new servers to the system in a virtual environment, and not worry about migration to future hardware," Tom Kilroy, Intel VP and co-general manager of the Digital Enterprise Group, told InformationWeek. "That means, if your Caneland system is about to fail, you can convert a whole machine over to a server running a Nehalem chip without shutting down applications."
The future migration and virtualization issue became apparent as previous versions of VMware software had be upgraded along with updated hardware. Going forward, that is expected to be less of an issue as VMware and Intel have worked together to optimize VMware ESX Server on the Xeon 7300, said VMware VP of R&D Stephen Alan Herrod.
