    Unanswered: SQL 2008 disk configuration


    We have been given a new 64 bit SQL data warehouse server with 2008 enterprise installed. Here are the specs given to us by the server admin group:

    Server Storage provisioning - two RAID-10 arrays have been configured with standby hot spares. Each array is one independent volume as follows
    D: 2.72TB
    E: 2.72TB

    The OS Volume (C runs a RAID-1 Mirror - total space of 465GB with 428GB currently free

    We have to migrate about 15 user databases from our current data warehouse to the new server and I'm trying to figure out the best way to configure the data and log files. I was thinking of separating out the data files to D: and log files to E:, but not sure if having just the log files on E: is overkill.

    I was also thinking of moving tempdb over to the D: and tempdb log over to E: to take advantage of the RAID 10, but not sure if it is a good idea to have tempdb on same drive as data files.

    Any suggestions would be helpful.

    Definitely data on D: and Logs on E:

    Some people argue for tempdb to be on its own physical disks - but without that available I tend to split that (data and logs) with the rest of the files.

    Backups - again people have different views but I'd go with E:
