We are looking for the lowest hardware cost setup to upgrade our exchange 2003 cluster (A/P) to exchange 2007.
I would like to know which clustering or HA scenarios to implement, i.e SCC or CCR.
We are planning to have 3 servers; two for Mailbox with DiskArray and one for Hub/CAS roles but seems the DiskArray is costing higher, and increasing our budget. So not sure to go with CCR (w/o SAN) or SCC.
Also we will be eliminating our Rightfax server, and having the fax services in Exchange 2007 UMS. Do we need any additional hardware and Different CAL licenses.
We need a scalable setup with lowest cost which provides HA; and can be expanded in the coming years.
