Thanks for questions.I will attempt to answer most of them.
> it seems that for OnCommand Unified Manager to receive performance data, one must be on 6.1 & use Performance Manager 1.0
Yes thats correct.
>Is Performance Manager going to be a VM appliance ala OCUM 6.0 (and presumably 6.1)?
Yes this will be an OVA too.
>Any thoughts as to whether those will provide the stats that I'm looking for? Or do I have to wait for 6.1 & 1.0? Will there be license charges for the latter?
These are not licensed. For perf data you would need to use OCUM6.1 and OPM1.0
>when will those be available for download?
Download would be made available soon. I will update this thread as soon as the download is available. Appreciate your patience
