We are currently using BMC as our capacity planning tool for our VM farms however, we have recently got VEEM and I was wondering how it it works under the covers. In our Environments all our virtual desktops are sitting at the Ctl alt delete screen so are all booted up waiting for someone to login and once they do the apps are downloaded. Using the BMC tool I can see that we have 370 desktops taking load however, not all of these desktops are active, maybe half are active, but comparing an active desktop with an non active desktop there is very little difference in ghz. Does VEEM do something different from the BMC tool? How does it distinguish an Active desktop from an non active desktop? I'm trying to work out how many active desktops at peak time can fit into our DR site should we have a DR situation. I'm hoping this is the right forum apologies if not - its all very new to me the forums.
