I just built our new vSphere 4 ESX Cluster environment - and before I start moving machines from our 3.5 environment, I obviously want to perform a list of valid tests (performance, failover, HA/DRS stability, etc)... and while most things that I should look for certainly stand out, there are always things that others might have done that I could easily miss.

The environment I built is as follows:

3 x Dell PE R710 Servers (2 x 4 CPU Xeon Core 2 @ 2.93GHz)
72 GB Ram
800 GB Raid Local Storage
iSCSI & FIber attached Compellent SAN (iSCSI is not a primary path, and will eventually be phased out)

HA, DRS is enabled on the Cluster of 3 Servers.

Has anyone created such a test plan layout for their organization (and would be willing to share those steps with me?)  I have a typical testing-plan document I generate, and usually know what steps to go through.. but if anyone has some suggestions, that would be awesome.

Plus it's worth 500 points ;)

Thanks everyone, your help has been invaluable.
