Server Configurations - SQL 2008 R2

  • Hi All,

    I am in the process of putting together a proposal to upgrade our Production Server and wanted to ask a couple of questions of the experts on this site.

    Basic Specification is ;

    Windows Server 2008 OS

    SQL 2008 R2 - Single Default Instance

    ERP System with 6 Databases of around 6 gig each ( 36 gig total ... this is 4 years of data )

    Daily / Hourly tasks running

    Full Backup @ 2am

    T-Log backup every 2 hours from 6am - 10pm

    Processor - is a given that it will be high spec

    Memory - 16gb or 32gb

    I am looking at the following for storage;

    PARTITION 1 - RAID 1 - OS ( 2 Drives 300gb each ) or 500gb depends at time of purchase

    PARTITION 2 - RAID 1 - SQL Databases and Indexes ( 2 Drives 1 tB each )

    PARTITION 3 - RAID 1 - SQL Logfiles ( 2 Drives 1 tB each )

    PARTITION 4 - RAID 1 - TempDB ( 2 Drives 1 tB each )

    PARTITION 5 - RAID 5 - Backups and software storage/updates ( 3 Drives 1 tB each )

    Thoughts and suggestions on configuration please

  • That's a very low number of drives for each RAID array. Low usage DB I presume, since they are pretty small...

  • Hi Gail,

    Thats why I am asking for suggestions - the book said to set up the Raid 1 and Raid 5 for Backups - but not about sizing or number of drives.

    The space is correctly identified - so could have 4 500gb drives on Raid 1 possibly ?!

    Thanks

    Steve

  • I hope the book didn't say RAID 0, because that's something you never want to use for a database.

    IO throughput is a function of the number of spindles you have in an array, the more spindles, the higher the data transfer rate.

  • definetly not RAID 0
