Which Edition of Exchange Server to Deploy? October 8, by Paul Cunningham 54 Comments If you're planning an Exchange Server deployment you will need to consider which edition of the product to deploy on your servers. For Exchange Server there are two editions of the server product itself, and there is only one difference between them which is the number of mounted databases per server. A mounted database can be an active mailbox database that is mounted for use by clients, or a passive mailbox database that is mounted in recovery for log replication and replay.
While you can create more databases than the limits described above, you can only mount the maximum number specified above. The recovery database does not count towards this limit. Here's a few examples. In this example a single Mailbox server running Standard Edition has 5 mailbox databases.
All 5 databases will be able to mount, and an additional recovery database can also be created and mounted for any data restoration scenarios. The same server running Standard Edition with 6 mailbox databases will not be able to mount all of the databases at the same time. However, if it is running Enterprise Edition it will be able to mount all 6 databases, or up to databases. What about a database availability group? DAGs can have up to 16 members, and each member is limited by the edition of Exchange Server that is installed.
The DAG itself is only limited by the capabilities of all of its members. A DAG made up of 16 Standard Edition members, with each database having 4 copies, could therefore host up to 20 databases. The choice of server edition is purely driven by the number of mounted databases each server will be hosting.
For the Edge Transport role, given it does not host any databases, it makes sense to use a Standard Edition server license.
When you purchase your Exchange Server server licenses you'll be provided with a license key that needs to be entered on the server.
The license keys determines which server edition is installed, there is no different in installation media or installation method for each edition. All servers are first installed as a Trial Edition, and then you add your license key after installation is complete. You can upgrade from Trial to Standard, or from Trial to Enterprise. You can also upgrade from Standard to Enterprise.
However, you can't downgrade from Enterprise to Standard without completely reinstalling the server. This means it is feasible to initially license your servers as Standard Edition, and then later upgrade them to Enterprise Edition if your environment scales up e.
As a final note, the information above applies only to the server licenses. The Client Access Licenses CALs are considered separately, and have no impact on the server license you choose to deploy and vice versa.
