Any Citrix Guru's out there???

We are having performance issues and we are not getting any detailed technical info back as to what the potential problems could be.

If it's performance related and it's virtualised I'd say 7 times out of 10 it's bad storage design. People don't appreciate storage contention and think as long as they have enough disk space then they're fine, but if you have 500 GB of data spread out over two 250 GB disks, you're going to have more issues than if you have 500Gb of storage spread out over five 100 GB disks. That's very, very basic stuff. You size enterprise Virtualisation deployments by number of spindles you're presenting at the back end. You don't really worry about the amount of storage you have to present, just the number of spindles you have to present that will be able to guarantee your required I/O (because the second method should always result in a larger amount of storage being presented than the first).
