What I’m wondering is if Exchange 2010 is supported officially by MS to be run on vSphere 4 (or above)

I know it works, tested and tried it many times. But i would never recommend a customer to run an unsupported config.

Why it may not have been supported, it works. I run ESX 3.5 U4 and have a few MSCS clusters. I find it silly that VM says to disable DRS/HA so I don’t. DRS/HA rules work just fine. The only gotcha that I have run into is that when an MSCS cluster node is powered off, sometimes DRS will do a Vmotion of the running node to balance everything out. Unless VM has added something to explicitly tag something as an MSCS cluster, I don’t forsee this behavior changing.

This is great news for my team. We will be standing up a new production platform in 1Q of 2010 and up to this point have been planning to build two clusters because of MSCS.

Now we get the simplicity of building one and with DRS we will more effectively use all hosts, saving cost on scaling.

Euuh, the documentation actually describes what is supported and what isn’t

Hi,

is there around documents/kb for each version that describes in an overview what is supported and what not. Everytime when it will be interesting using possibilities, I got an answer from the support this is not supported right by now, but you can configure it.

Many thanks for your help.

Best regards

Although it is possible it was not supported before U1, with U1 it is.

Hi Duncan,

Concerning the disabling HA/DRS for individual VMs, isn’t this already possible per cluster by setting the Virtual Machine Options to “disabled”?

This is how I excluded the Exchange 2010 mailbox servers which fail on a VMotion while the rest of the cluster still uses DRS/HA. Or is this an unsupported configuration?
