Thanks for the input Al. Let me ask for more focussed feedback. Ignore the disk issue. I'm not asking about that. I'm talking about Mailbox/PF server functions on one box. FE functions are handled separately. By strictly comparing, 4 proc vs. 2 proc (and whatever Bus stuff might come with that or other things that I'm not familiar with). Why should I spend 4 times as much for a 4 way box over a 2 way box? --- "Mulnick, Al" <Al.Mulnick@xxxxxxxxxx> wrote: > http://www.MSExchange.org/ > > Hmm...
