  • Large Mailboxes

    If I wanted to move from 100MB to 2GB mailboxes would it be better to have more smaller storage groups or just one big storage group? I am trying to size my storage, but I was just wondering if it made more sense to have a bunch of small ones instead of one large one. I guess from a performance stand point it might be better to isolate storage groups on separate spindles. So you don't have all of your mailboxes always accessing the same set of disks. What do you guys think?

    The usual reason to split up the data is for disaster recovery purposes. I have run sites with large stores and if the storage up to it then it is fine. However the usual idea is to have Mailbox stores at around 50gb each, which provides a good trade off between store and recovery time.

    The only way you would get performance gains would be with separate drives for the logs and database for each store.

      Yeah I will probably store everything on a SAN so I think it should be okay. Is it possible to mount an exchange database from a server that goes down to a different exchange server that is up for disaster recovery if all the logs and data are stored on a SAN? thanks!

        You can mount the database from another server in a RSG, but not as the live database. The database is closely tied to the machine name.

          Thats what I figured. I guess one of the clustering solutions is the only way to always have the live database up. Thanks for the input!
