    Raid 5 performance

    I have 10 disks and I set up 2 volumes using Raid 5
    so each volume has 5 disks allocated

    Now Vol1 and Vol2
    But we have only one raid controller card

    will I face degradation in performance because I have a single raid controller card
    I do understand that this is a single point of failure (having a single controller card)
    but will my performance be significantly better if I have two controller cards
    compared to single controller card

    Yes you will see a degraded performance. How much you notice it would depend on the raid controller, and how much you are hitting it, with what type of workload.
