@Fahim -
The list of known issues that were created by changing over to cluster disks (missing perf data, missing 2008 clusters) and the "Processor Information" change are the reasons I don't recommend upgrading to this version of the Base OS MP. When those issues are fixed in a future update, I'll change the stance. 6.0.6958.0 is a pretty solid MP with a few smaller issues which I have long since blogged about workarounds. I like where the MP is heading - changing to cluster disks is the *right* direction, to have these hosted by cluster resource groups, but with this change, came a few issues that will be resolved soon.
