Should I use more then one database in Exchange 2010?


At the moment I'm setting up a SBS2011 from scratch. The network had about 50 cliënt computers. I was wandering if it is usefull to create and use more then one exchange database? Are there any advantages?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

If it is 50 clients, then one database is more than enough.
If you only have one database and it breaks/gets corrupted/etc

all mail users are down

If you have a few databases, then only 50%, 25% etc will be without mail

You can also apply limits to a database. In my old job, we had databases according to the mailbox limit, 100mb, 300mb, 500mb, 1gb

although with 50 users it seems a little overkill, but that will depend on how critical email is to your organisation

SBS2011 I think limits you to 1 DB if my memory serves.

Ok guys, thanks for the advice. I'll stick with one database for now.

@ Gordon, The SBS2011 standards limits to 5 databases according to Microsoft. Thanks for your effort to reply anyway
