RAID 1 support and Duplidisk

I recently received a Duplidisk 3 RAID 1 controller for SATA disks. It turns
out that I can’t use it, apparently because the DOS program that is used to
sync the disks up for the first time for a non-Windows OS does not support
SATA. I got in touch with Arco, and they said that they had other complaints
from QNX users about this. They also said that they were working on a
solution where the initial sync would be done from a Windows machine talking
to the DD3 via a serial port, eliminating the need for the DOS program. For
some reason, they have stopped answering my emails about this. So,

  1. It appears that they have Duplidisk 4 for SATA drives, where their
    website claims OS independence. Has anyone tried this with Neutrino?

  2. Has anyone any experience with the Windows sync software mentioned above,
    with a DD3?

  3. Can anyone recommend some other RAID 1 solution for Neutrino? I liked
    Duplidisk, but it sounds like they might not be willing/able to support OSs
    other than Windows and Linux.

Thanks,

Kevin

We use AccuSys devices (both PATA and SATA), they work fine for us.

Ah, good news! The Accusys stuff looks better than Duplidisk, particularly
since it does hot swapping and initial mirroring without having to run any
extra software.

  1. Can you tell me what models you have used?

  2. Since Neutrino apparently does not have a SATA driver, I have been using
    a SATA drive by setting the BIOS to “legacy” mode, and using the QNX EIDE
    driver. This is on a late-model Intel motherboard, D945GNT. Is this the
    configuration that you have used for SATA drives?

Thanks,

Kevin

We used 75130 (PATA version), now we plan to use 75170 (SATA).

We tested SATA version with QNX4 - it doesn’t have SATA driver, so we used
it in legacy mode. But it was working fine, so I would say it should work
also in QNX6.

Neutrino does support SATA on the Intel ICH5 chipset and I understand
that support for the ICH6 is work in progress.
