    * RAID configuration - is it possible?


    I have a question about how to setup RAID array and if this is possible at all.
    So here is what I have:
    CPU: 2x Quad-Core X5560
    motherboard: Intel S5520HC with attached hardware raid AXXROMBSASMR (LSI 1078 4-port SAS HW RAID controller)
    memory: 6x4GB DDR3 1333Mhz
    Hard-drives: 2x 300GB Seagate Cheetah 10k rpm SAS (RAID 1)

    So what I want is to add 2 new SSDs, but with the following configuration:
    The current SAS disks should stay in RAID 1 (mirror)
    The new SSDs should be configured as RAID 0 (strip)

    At the end I should have two partitions - one with the old drives and the other one with the SSD. Is this possible with only one RAID controller?

    If you can connect all 4 disks on the same RAID controller (so if the RAID supports 4 disks or up), I don't see why it wouldn't work

    Just depends on the raid controller, not worked with that one but most LSI controllers will allow multiple luns like you are wanting.

    Yes most new raid controllers should support this I see it done all the time. More than one RAID set... 1 + 0, or 1 + 5, 1 + 10, etc
