Start small. First change your drive array. For a 1,000-user server you should have:
C: RAID-1 (2 drives) OS and binaries D: RAID-1 (2 drives) Exchange transaction logs (only) E: RAID-5 (3+ drives; recommend maybe 5) Exchange database files By separating the logs from the OS, if you have a major disk failure on either the log volume or the database volume (but not both) you should be able to recover everything up to the point of failure. Next, you should have a "recovery server". If that server can serve in a pinch as your primary server, even if it's a little slower, it gives you something you can put into service quickly in the event your production server fails. This single measure will cost you little but will give you perhaps 75% or more of the "high availability" you seek. Clusters and SANs offer only marginal improvements over the above at substantially higher cost.

Little Background: Last week, Exchange 5.5 server went ka-poot early in the day and I was unable to recover the IS. We ended up losing 11 hours of data that was not on a backup tape. A key member of the management team has had the stance in the past that email is "best-effort". I knew that would fly until the time that messages and calendar info was lost. I was right! Where there was no money before has come lots of money to make Exchange high availability. Amazing what a little data loss can produce...huh? Anyhoo, my task now is to find information about either SANs, Clustering, Mirroring....???? Any suggestions or comments is always appreciated by you.
