  • Splitting exchange 2003 Information store

    Hi,

    We have an exchange 2003 enterprise server with one IS of about 200gb, my concern is over time should we ever need to defrag that is it would take a very long time....

    Is it possible to split the existing IS which has 5 differents businesses email into those business units, making it potentially easier to manage if required....

    If it is possible, could you advise how...

    Thank you in advance
    Benjapos

    You have, IIRC, 20 databases in Exchange 2003 enterprise
    (http://support.microsoft.com/kb/822440)
    Create your structure and use the mailbox move process to do them a few at a time (out of hours) until the original IS is empty, then delete it

      Great thank you.

      How do you create the structure, right click first storage group NEw mailbox store ?, then right click on a mailbox and move it to new store ?

      Is that all i would need to do ?

      Does that move process change any settings or anything that would require tweaking after the move ?

        You can create up to 4 storage groups with 5 databases (stores) each
        And yes, right click on mailbox in ESM and select Exchange Tasks then Move Mailbox

        Only tweaks will be to set up appropriate size limits on the new stores before moving mailboxes but everything else should be transparent

          Thanks for the quick response,

          if in the future i have two stores with two databases in each.

          I needed to defrag one of the stores, would the other one be able to stya up and running during the defrag, or will it only redce the defrag timeframe ?

          (its been a while since i had to defrag an exchange db and so can't rememebr if i have to stop servcies...)

          Thanks again

            IIRC defrag involves taking a store offline and does not affect other stores or Exchange services
            Sembee will jump in if I'm wrong

              I wouldn't even consider an offline defrag.
              If you have Enterprise edition just move everything off the large store in to smaller ones and drop the original one. Zero risk, zero downtime.

              On a 200gb store you are looking at downtime for those users of 2 days or more (offline defrag processes at between 1 and 4gb per hour hardware dependant).

                Thanks Sembee,

                So by creating the new stores and databases would eliminate the need for a defrag. Would i be able to create new stores and databases everytime i would want to clear the datbases ?

                  You can create a maximum of four storage groups with a maximum of four mailbox stores in each one. Therefore as long as you don't max out what you can create, if you go through extensive content removal then shuffling the data around does away with the need to do an offline defrag.
