RAID Trouble

    Hey all,

    Have two old blades (****, but beside the point) that I'm trying to get going. They function fine non raid but I'd like to have hard raid on both. Thing is I'm not sure if I can now with the current hardware.

    IBM eServer 326[Opteron 250/4GB]
    LSI Logic SCSI Controller
    Sli SataLink Controller


    My drives are SATA, so obviously I'm using the Sli controller[ 3512A SATAlink BIOS Version 4.3.534 ]. Thing is, googling seems to suggest that it might have RAID support(I only want 0) but I never get the Ctrl+S/F4 prompt such as to configure it from the bios. Post here though says "it will say something like "SATALink" with the non-RAID version. "

    Oh and Ubuntu 11.10 labels it a SATA Raid controller.

    Does it support raid? and if so how do I enable/configure it?

    Thanks,
    ED E.

    How many disks in each? I've found in some HP servers that if two disks are found it automatically creates a RAID array.

    Just two 80GBs. I wish it were as simple as plug and play.

    if is on-board controller,you have to go in the motherboard'BIOS and not in controller'BIOS for settings.

    If all you want is RAID 0 - i.e. span the two disks - does it really matter if you use hard or soft RAID? Performance wise, I can't see it making much of a difference.

    I mean if you have two disks and use LVM to present them as a single volume, will that not get you pretty much the same result?
