Here in Chemistry, we have a pair of 32-bit Dell Windows Server 2003 computers in an active/passive fail-over cluster running Exchange 2003 Server. They both connect to a dual-SCSI raid array with a stripe-set for the Exchange store and quorum and log disks. It works very well for our ~400-600 or so clients. Looking to upgrade to Exchange 2007 on 64-bit hardware fairly soon, hopefully. Thomas P.

If you could take a second and quicky reply with what department you are in, what software you use and what version, and possibly in what configuration (ie. Clustering, exchange FE/BE, etc). Much appreciated from your friends at the physics department- /Ehren Ehren J.
