Thanks for all the info guys. I designed a new multipurpose server that will do all our file sharing and misc. data storage on a new 1.5TB (1.8TB total space) server. It is a Dell Poweredge 2950 with all the fixins so it can be used in a number of jobs if need be.

For those that like specs it has 6 X 300GB 10K RPM SCSI drives (raid 5 setup), 4GB Ram, 2 X 2.33 GHZ dual core 5140 XEON processors (4mb cache each) with a 1.33 GHZ bus speed, and of course preinstalled with MS Storage Server 2003.

I think the SNAP server will be a great way to backup the storage server. So that is next on my list since I don't think our current backup server can handle the exchange, app server, and storage server space requirements.
