  • Exchange 2003 standard what happens when it reaches the limit of 75GB

    Hi All
    I have a server which is running Exchange 2003 Standard with SP2 where the database files are:
    priv1.edb = 49 GB
    priv1.stm = 25 GB
    Can I just clarify the 75GB limit that is on the standard edition. Is that 75GB with both the edb and stm put together or is it seperate.
    We run the mailbox management process on a sunday evening.
    What exactly will happen once the limit has been reached? I know in the past we have had the store go offline. Is this all that will happen.
    I have had a look at our environment and email is now available to more users than ever. We have grown an extra 100 users in the space of 3 months.
    Currently this server is a VM inside an ESX4 cluster. Its a Windows Server 2003 Standard edition (32bit only) and I am concisious that exchange by defulat consumes all the memory which is has already done. I know I can't expand the memory unless 64 bit is installed but want to refrain from doing this as it would make more sense to upgrade. The issue is the cost of 100 or so licenses which are still 2003 licenses and would need to be upgraded. I also notice a lot of spikes on CPU usage which on occasions I have seen between 75% and 90%.
    I want any ammunitation you folks can give to make a case for us to upgrade to Exchange 2010.
    Any thoughts are welcome...

    Thanks

    the store will dismount once it hits 75gb. because you';re only running exchange standard, you won't be able to add another store either.

    i would strongly push for the upgrade path - you get much more usability, managability, security, and stability with ex10..

      The store will dismount each day at 5am (by default). It can be remounted immediately afterwards. I am aware of a number of locations that have scripted the restart of the information store service to get round the problem.

      Do be aware that the limit is NOT the physical size of the database, but the logical. The logical is the physical size minus the white space. Therefore it is possible for the database to exceed 75gb in physical size and continue to operate.

      As for the upgrade, both Windows 2003 and Exchange 2003 are almost or have gone end of life. That means patches for issues and support will start to fall away. The upgrade to Exchange 2010 standard in my eyes is an easy decision to make, simply on the support grounds and the support of the larger databases.

        I have a follow on question sembee, mainly for educational purposes.

        You mention that after a dismount at 5:00am, you can just remount the store.

        Assuming a world where noone ever deletes or moves email, there would therefore be no downward-movement of the size of the store.
        But the store would continue to receive email. Would it actually continue to grow? is there ever a point where it's just going to throw up it's hands and refuse to remount at all ?

          The hard limit on the database I believe is 8tb. Hit that point and it will not mount at all. Although I have never seen one get that big. Had to deal with a couple of 2tb databases in the past, but no one has got that big that I have seen.
