    Hi managers!

    I've a TruCluster environment, 4,0f and I've to add another member
and more services to the cluster.
    At this moment I'm using RAID 1, because we wanted to have the data
and the indexes of our databases in different logical volumes in order
to get a good performance. But now that we have to buy a lot of new
disks, I'm thinking on changing to RAID 5, and put data and indexes of
the same database, and the application wich access that database in the
same RAID 5.
    Have you got any experience on these situations and how this can
affect to performance?
    Thank you very much in advance.
