We are currently running Exchange 2003, 200 mailboxes, 250MB caps. I would like the designed for growth to at least 300 mailboxes and 1GB of storage. I also plan to run one Exchange server and combine the roles.
This is what I have spec'd so far:
1 - Quad Core Xeon E5420 Processor2x6MB Cache, 2.5GHz, 1333MHz FSB, PE2950
8GB of RAM
73GB 15k Mirror for the OS
146GB 15k Raid 5 for the DB
Is this too much system, not enough or just right? Any additional recommendations?
