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).
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.

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?
