Hello,
I am in the process of deploying Exchange 2013 in our environment, it will co-exist with Exchange 2010 until we move everyone over to the new server.
My question is regards to the disk storage design, we have a SAN that Exchange will share with the rest of our Virtual Machines. I plan to have 20 live databases and 20 archive databases so I can balance out mailboxes per database so that each db is roughly 100GB in size.
The goal is is to keep the size down so that any database specific maintenance can finish quicker and if I ever had to deal with db corruption it is faster to restore, backup, etc.
My question is, is there a lot of overhead I will be adding onto the Exchange server by having 40 databases mounted?
Currently 300 users, 3.5TB in exchange databases between live and archive mailboxes (no mailbox caps), with 40 databases (20/20) it spreads out nicely with roughly 15 users per db, and db size is roughly 100GB.
My concern is having 40 databases mounted on a single EXCH2013 multi-role server? We have no DAG, etc.
The machine is a 4vCPU/32GB and the disks are on a Compellent tiered SAN shared among other VMs.
Thanks.
