Standard or Enterprise?


Standard or Enterprise?

One important decision that administrators have to make prior to installing Exchange Server 2007 would be whether they want to install the Standard or Enterprise edition of the messaging software.  The primary differences are that the Standard Edition of Exchange 2007 allows for the creation of up to five storage groups and five databases per Mailbox server.  In terms of High Availability options however, the Standard Edition of Exchange 2007 is limited to just local continuous replication (LCR) and standby continuous replication (SCR).
On the other hand, the Enterprise Edition of Exchange 2007 supports the creation of up to 50 storage groups, and up to 50 databases per Mailbox server.  All four flavors of High Availability are available in Exchange 2007 Enterprise, including LCR and SCR, as well as cluster continuous replication (CCR) and single copy clusters (SCC).  It should be noted that in order to use CCR and SEC, the Enterprise edition of the underlying Server 2003 (or Server 2007) operating system is also required for its clustering capabilities.
