How many users are you thinking of supporting in order to warrant clustering. I am running exchange 2007 boxes on vmware esx but we have only 600 mailboxes on a single mailbox server, however we have exchange 2003 servers, soon to be upgraded, in 3 other countries which handle load as well. Possibly if I had not inherited it and had my own choice I would have used hardware for the mbx servers and vm's for the cas,ht servers only for the idea of better resource utilisation but we are not seeing any performance hit and don't expect to.

If you go with Vmware still you can use the HA option. Cheers!!!

I certainly can't speak Hindi or Punjabi or anything else (and I'm making a presumption based on the OP's name that he is East Indian). Generally, a "I don't understand, could you ask it a different way?" is more tactful. Regards, Michael B.

What does this sentence mean? And what kind of English is that? Try to explain it in simple English.
