  • 1.  vSphere CPU compatability for vMotion - Intel Xeon

    Posted Sep 12, 2011 09:34 PM

    Can someone point to an article that shows which Intel Xeon procs are compatable in a vSphere cluster?

    Can a Host with a Xeon 54xx series procs join a cluster with Xeon 55xx series procs or a 56xx series procs?

    Thanks

    Take a look at http://kb.vmware.com/kb/1003212 which lists the compatible CPU types. The article has not been updates for ESXi 5 yet, so you may see different EVC baseline names in vCenter 5.

    Hosts with differing processors from the same family can added to the same cluster. It's only when you start wanting to use vMotion and DRS and all of the nice stuff that you need to worry about EVC (Enhanced vMotion Compatibility) which effectively sets a baseline for CPU features presented to the VMs by the ESX hosts, which evens out the playing field when there are a mix of CPUs in the cluster supporting different features. There are quite a few baselines you can choose from, just pick the highest baseline that is supported by each host's CPU, the GUI for EVC configuration will tell you this...

    Thanks guys. Unfortunately I don't have access to that other cluster. All I know is their procs are 56xx series Xeon.
