Exchange 2007 Store Related Changes and Improvements

http://msexchange.org/tutorials/Exchange-2007-Store-Related-Changes-Improvements.html

Exchange Server 2007 comes in two flavors, a standard edition and an enterprise edition, just like previous versions of Exchange. The Mailbox Server when talking about the Exchange Server 2007 Standard edition supports a total of 5 Storage Groups and 5 databases. Unlike Exchange 2003 and previous versions of Exchange there’s no longer a database storage limit in the standard edition. The Mailbox server in the Exchange 2007 Enterprise edition supports up to 50 Storage groups and a maximum of 50 databases per server. Exchange 2007 allows you to create up to 5 databases in each Storage Group as is the case with Exchange 2003, but best practice is to create 1 database per Storage Group. So why should you have a one to one relationship between storage groups and databases? Well primarily because you’ll be up and running a lot faster considering disaster recovery scenarios, etc.

You may experience slow client performance if the version store runs out of memory in Exchange Server 2003
