Besides, SME backup and restore at the LUN level. If you put all of the databases on the same LUN, you would be restoring all three databases even if you only had a problem with only one database.
Why do you want to put all three databases on a single LUN?
I think that it would make management much easier, for exchange and netapp too.
Each box would have 2 drives, LUNS, let say F: (for db) and G: for logs. So 4 total LUNS on netapp to manage, 2 per controller = 2 per exchange box.
If i go with separate LUN per storage group i need 4 drives per exchange, 3 for db, 1 for logs (if im correct, or 6, 3 for db, 3 for logs). So from netapp side i will have to manage 6 or 12 LUNS, just for exchange, 4 to 6 per controller.
Just looks much simpler and easier with 1 LUN for DB and 1 for logs per box.
So if SME backups and restores at LUN level, there is no granurality involved? no way to restore just one DB from that LUN, do i have to restore full LUN?
