My larger clients tend to group users based on: [a] mailbox quotas, and [b] first initial of last name.
[A] makes sense to me (so you specify a quota based only once per mailbox database and not for each and every user). [B] is purely arbitrary and is just a way to split up users between databases. Some also have separate mailbox databases for VIPs - "to be restored first in the event of a catastrophe". But that's starting to go away since Exchange 2007 and CCR; even more so with Exchange 2010 and DAGs... I would aim for a common size. Regards, Michael B. Smith Consultant and Exchange MVP http://TheEssentialExchange.com From: Pfefferkorn, Pete (pfeffepe) [mailto:pfeff...@ucmail.uc.edu] Sent: Tuesday, October 12, 2010 9:39 AM To: MS-Exchange Admin Issues Subject: Exchange 2010 DB SIS question and user placement We are currently running Exchange 2007 and we are formulating our plan to move to Exchange 2010. Currently users are logically located on specific databases based on their department. This was primarily for the Single Instance Storage for 2007 and DB's. Now with 2010 I'm to understand that the SIS is gone. So my question. Is there any reason to continue to group users based on their department designation to specific database or would it make more sense to randomly spread them between various Databases. Is there any technical advantage to placing like users who correspond between each other onto the same database? Message will still have to hit the hub for the mail delivery. If we randomly move users to various Databases, I would think that our DB's would average about the same size for the most part...more so than is the case right now since some departments have a high user base and some have a low user base and our DB's range from 13 gig to 175 gig.
