Hardware Transparent SCSI Raid-1 Card Available?

Hardware Transparent SCSI Raid-1 Card Available?

Post by Ken McCor » Wed, 20 Oct 1999 04:00:00



Does anyone know of a hardware-transparent SCSI raid-1 card?  By
hardware transparent, I mean that 2 scsi drives are mirrored together
and appear as only one drive.  There's an IDE solution from
www.arcoide.com that looks nice, but I'd rather go SCSI.

Thanks,

Ken

DPT makes a bunch of raid scsi cards - check out the SmartRaid series.
They do mirroring transparently.

As far as I can tell, they're not totally hardware transparent.  The
Arco card sits between the hd controller and the drive.  It doesn't
require any kind of driver to be used.

Check out the CRD-5440 at www.cmd.com. I think it is os independent.

Yes it does - it uses the ide driver. Similarly, a
"hardware-transparent", as you call it, SCSI card, would use the driver
for the SCSI controller. It's the case with the DPT boards, which use
the eata SCSI driver, although the raid is done completely in hardware
(the raid function itself doesn't require any driver at all). If what
you're looking for is a add-on card for a pre-existing SCSI controller,
I'm sorry, but I don't know of any.
