  • Exchange 2007 Practical Database Size

    I do know the max size limit on exchange 2007 Standard and Enterprise.

    My Exchange Server 2007 ENT is a Hyper-V instance and has a 80gig database file. The exchange server uses a Raid 1 disk array with 8 gigs ram, and 2 processors. RPC is bit high but liveable until the spindles are changed from 7.2k to 15k mid-next year.

    The 80gig EDB file is in first storage group and second storge has the public folders at 1 gig. What size should this be broken up into when users = 150, if that is used as a variable?

    Thank You

    Single Array?

    You will gain nothing by doing anything with the databases.
    Size of the database can be whatever you like from a performance point of view. The main reason for splitting data up is data recovery.
    However if you have multiple storage groups (as the Microsoft recommendation is one database per SG) then you will see a big performance hit on a single array. You will be seeing a hit now, as throwing RAM at Exchange still doesn't remove the storage bottleneck.

      I'd agree with Sembee.

      When you replace the disks, move them onto a dedicated RAID controller. Do away with the RAID 1 ideally as well, RAID 5 would offer better fault tolerance.

        While RAID 5 can offer better fault tolerance, it isn't always the best choice.
        You need to have two arrays at least, not a single large array.

          I suggested moving the data array to a separate controller too
