    Linux SATA cards and RAID

    Hi All,
    I've currently got some SATA port replicators in my Linux (Openfiler) NAS. The problem is that they don't provide true sata interfaces, so when a disk drops out of a software RAID array, and it is replaced, rather than appearing as for example /dev/sde it appears as the next disk at the end of the array (for example /dev/sdn).

    Can anyone recommend a proper SATA expansion card? I'm not bothered about it doing RAID/fake RAID, I just want it to present a load of real interfaces.

    Cheers...

    Re: Linux SATA cards and RAID

    Actually, I'm after a 5 or 6 port card. I have 5 in 3 bays to connect them to, and don't want to split arrays across controllers. Any recommendations, and do they definitely present true paths, ie if I install a disk on interface 0, 1 and 5 it presents as:

    sda, sdb, and sde

    rather than

    sda, sdb, sdc

    Regards...

    Re: Linux SATA cards and RAID

    You're really going to have trouble find any SATA controllers with more than 4 ports that doesn't have an expensive I/OP and real RAID BIOS.
