  • Question

  • Hi,

    We have 4 storage groups each hosting 1 EDB.  Can we consolidate these 4 EDBs into 1 storage group?  If so, what are the pros and cons to doing this versus what we now have?

    That would go against Microsoft recommendations. Back in the 2003 SP2 days, the recommendation changed to one DB per SG as you have it set now. I would leave it that way:

  • Hi

    Do you have any clustering enabled (CCR or SCC) as this requires one DB per storage group?

    Cheers, Steve

  • Hi ,

    Agree with Andy.

    Each storage group you can only backup or restore a database once. If you have multiple storage groups, you can backup or restore multiple databases at the same time.
