    SATA Raid Setup Conundrum

    Here's my puzzle. Asus P5B-VM motherboard with "Jmicron JMB363 SATA and PATA controller"

    4 SATA connectors on the motherboard. Also, 1 "Raid" SATA connector.

    If I plug the SATA drives into the standard SATA ports, they are not recognized by the RAID Bios.

    If I plug the drives into the "Raid" sata connector, then the drive is recognized as being valid for RAID-ing. But the problem is, of course, ONLY ONE PORT!

    So it's a Catch-22, I can have raid capability, but only for one drive. (Maybe it's more of a paradox).

    I've asked at Asus's user forum, but I thought I'd throw this out to see if it's a problem anyone's seen before.

    The obvious answer is that this was made to be used with a sata cable with connectors for multiple drives. But, I can't find one forr sale anywhere, and I've never heard of such a thing.

    Re: SATA Raid Setup Conundrum

    A quick Google finds Good Board, Tacked on RAID
    Cons: RAID function is near useless.
    Other Thoughts: The RAID controller works on the external SATA and one internal SATA port ONLY. Be aware of this and don't plan on using the 4 main SATA ports in a RAID.

    Elsewhere:
    If you want RAID, you need the ICH8R Southbridge, which can be found on the almost identical ASUS P5B-VM DO which includes their Matrix RAID features (and 2 extra SATA ports).

    Followed by:
    Cons: The onboard NIC doesn't work with Fedora Core 6. RAID is a joke (it's fake raid actually). The worst part is one RAID drive has to be external. The alternative is to buy an eSATA->SATA adapter (Newegg has them for a few bucks). Even then I couldn't get Fedora to work with the JMicron controller. If you need RAID, DO NOT BUY THIS MB. I ultimately set up a soft RAID solution using the Intel SATA connectors. And I had to buy a separate NIC. Do not buy this board if you're running Linux. Spend a little more on a higher end board with a network chipset that has more support. Otherwise you'll pay more adding your own NIC.

    Other Thoughts: In all fairness to Asus, the documentation does say that RAID has only one internal connector. But that's just the dumbest thing I've ever heard. They shouldn't have bothered to include ANY 'raid' options. Maybe it works fine with Windows. But I would strongly discourage this MB if you plan on running Linux (I tried Fedora and Ubuntu). I can't comment on Windows. Maybe Windows has more support for the network adapter and fake-RAID.

    Ouch. I have 12 of these in custom built CAD workstations. I specced the P5B-Deluxe, but at the last minute, my vendor couldn't get that board for some reason and substituted this board.

    Uggh. This project has been just a constant stream of problems since mid-December <img src=/S/bwaaah.gif border=0 alt=bwaaah width=123 height=15>
