DPM 2010 Storage : SATA vs SAS RRS feed

  • Question

  • Hi guys,

     

    We're just evaluating DPM 2010 and were trying to piece some indicative pricing together, however this largely depends what we could get away with on the storage side of things.

     

    We've got about 70 servers to back up, 10 or so are holding 50GB worth of SQL data, the rest are light usage file/web/apps servers.

     

    How are people finding 7.2k RPM SATA disks performing in their DPM enviroments, are they fast enough to keep pace with the incoming data?    Or do you really need to go for SAS disks on anything more then light loads?

    Something like an HP ProLiant DL180 G6 with 14 x 2TB drives seems to be a good option, any comments on whether people feel this disk configuration would be overwhelmed in a medium sized enterpise enviroment?   

    Thanks for any insights!

     

    Steve.

  • Hey Steve,

    The easy answer... Yes.  It can hold the incoming data.  As a matter of fact, I even run it for demo / presentation purposes on a much slower configuration and it still works.  So no need to go for expensive SAS disks.

    I do advise however to put the OS on a RAID 1 SAS configuration.

    Just my two cents,

    The only issue you will have is when creating the replica's initially, that will be a bit slower, but then again, the price difference of SAS and SATA will not cover the initial delay I think ;-)

    Cheers,

    Mike
