Performance counters to watch before P2P Windows

[ejward]

This would be so much easier if capacity planner was free.

Rather than just P2V'ing a server and adjusting the memory, CPU, etc after the fact like I have been doing, I'd like to size it right from the beginning. It's tough to P2V it as 2 CPUs then take one away later.

What performance counters should I run in PERFMON before P2V'ing? I'd like to let PERFMON run for a week or so to get an idea of how much CPU to give the virtualized version.

Hi Ed,

I think you'll get better response in the Server/DC forum, I'm guessing you are using ESX, so I moved this thread to the Strategy and Planning forum. This is probably a more appropriate place for it instead of the Converter forum.

Thanks. I'm never quite sure where to post questions like this.

Perfect \!!! Thanks.
