Exchange Server 2007: Comparing editions and CALs


We get the following questions quite often:

What will be the difference between Standard and Enterprise versions of Exchange 2007?

What about CALs (Client Access Licenses)?

And the answers are on this page.

    Hi, in the Standard Edition is it 5 Database for storage group or 5 Database in the sum of all Database of the storage groups?

    Thanks

    Best regards

    Nunof,

    5 databases are the maximum. You can have 5 DBs each in it’s own SG or 2 SGs one with 2 and one with 3 DBs, as you wish. We suggest to use 1:1 ratio. Also – if you want to use LCR, you will have to use the 1:1 ratio (both LCR and CCR enforce it).

    Can server versions be mixed for different roles?  i.e. Standard edition for Client Access role, but Enterprise edition for the Mail Box role.

    Similar to FE/BE in 2003 today.

    Thanks,

    Mike

    Thanks for the answer. But one other think. If i install the edge roll in one server and all the other rolls in another server, how many licences i need? After all, all the roles are installed only in one place.

    Regards.

    So there won’t be a software imposed storage limit on standard?  What does it mean by hardware – if ihave a 250GB available, could i have that large a mailstore?

    Daniel,

    The answer is yes. :)

    Hardware and your backup/restore window is what will limit the practical size of the database for you.
