Vmotion DL380 G5 with new G6

Ed Cox — Fri, 23 Oct 2009 01:03:28 GMT

Hello ...

Question:
looks like the customer has the DL 380 G5s (Quad-Core X5450)in a cluster and is curious about adding G6 servers into the existing cluster.
However...I don't think he has EVC enabled.

Can you go back to a VM Cluster and enable EVC if it was not enabled at the time of cluster creation?

Assuming customer has proper Vcenter version (v4 I believe?) are there any other potential issues?

Thanks in advance!
Ed

Hi,

I beleive the issue will be, if you try to move vms from non EVC enabled to a EVA enabled, it will throw error.
If you shutdown the vms and bring it up on this EVC enabled node, this will work.

Also, if the no execute is not enabled, this shows incompatible hardware in VC and will not allow to enbale EVC

Very good...thank you.

As a quick follow up...

The customer actually has not yet set up a cluster with his G5 server. So he's going to buy a DL380 G6 and VSphere 4, set up the cluster and bring in the G5.
Does that sound feasible?

I believe the G6 Nehalem SSE 4.2 and Popcount features of the G6 CPU will go unused due to being in an EVC enabled cluster with a G5, but that's what he wants to do.
Thanks!
Ed

If it is a new cluster, then should not be an issue.
