Hi Are you going to use physical or virtual? Single server or cluster installation?Jonas Andersson MCTS: Microsoft Exchange Server 2007/2010 | MCITP: EMA 2007/2010 | MCSE/MCSA Blog: http://www.testlabs.se/blog

single server

Ok I would size it with at least 12GB ram (maybe even 16gb) and depending on disk's and server selection and also how much storage you need In best case I would setup the server with: C: RAID 1+0 OS/System D: RAID 1+0 Application E: RAID 5 Exchange DB F: RAID 1+0 Exchange Logs Jonas Andersson MCTS: Microsoft Exchange Server 2007/2010 | MCITP: EMA 2007/2010 | MCSE/MCSA Blog: http://www.testlabs.se/blog

how about IBM X-series with dual processor and some 20 gb ram

Yes sure! That should do the work :-)Jonas Andersson MCTS: Microsoft Exchange Server 2007/2010 | MCITP: EMA 2007/2010 | MCSE/MCSA Blog: http://www.testlabs.se/blog
