We're trying to stick under 500GB per store. In the event DAG fails and we have to go to tape, FCP LTO-4 can restore 500GB. It'd blow the RTO but really bad stuff does happen.
From: Paul Hutchings [mailto:paul.hutchi...@mira.co.uk] Sent: Tuesday, March 08, 2011 12:34 PM To: MS-Exchange Admin Issues Subject: Exchange 2010 Migration Planning - Database Size? I've been getting conflicting suggestions on the sensible maximum database size to use when we go to Exchange 2010. Initially we should be going with a single HT/CAS/MBX box with a view to perhaps bringing in a DAG pretty soon. Some people are suggesting 200gb is the biggest they'd let a single database grow to, some MS docs suggest 2tb. If I split our users across three databases we'd be well under 200gb per database but if we increase mailbox quotas we may stray above. Assuming proper storage/lots of IOPS/spindles etc. what is the "sweet spot"? Between SAN snapshots and our backup software I'm not expecting RTO/RPO to be a significant issue.
