Exchange 2010 Setup - Hard Disk Partitions

    Question

  • Hey all,

    We're preparing for an Exchange 2010 deployment, and I have a question regarding the server setup.  We have an HP Proliant DL380 G5 with 8 Hard Drive bays that we plan on using for our new Exchange server.  From what I've read, Best Practice is to create a seperate volume for the OS, the Log Files and the Database.  I have a running debate with my boss about this, as our server has only a single SmartArray Hard Drive controller.  His feeling is that having a single array controller negates any benefit from creating additional volumes and wants to RAID6 all 8 drives, then create seperate partitions for the OS and the Database.  I feel that the best way is to create a RAID1 volume with two drives and make two partitions (one for the OS and one for the LOG files) then RAID 10 the remaining 6 drives for the databse.

    Any ideas on this?  Are we both off base?

    Thanks!

    The idea of the RAID 6 is the major flaw in his plan!

    The single array controller won't make a massive difference to the performance benefits of having dedicated spindles for OS, log & DB, which is really what you should be trying to achieve.

    First- read this . It gives you some essential info and best practice. Best tool to use to determine what disks/raid is the Mailbox Server Role Requirements Calculator .

    If you want to compare/validate your storage - use Jetstress (for DB level) and Loadgen (Client simulation). These should back up your case and also prove that your config will indeed support your clients.
