IDE controller cards with >= 4 *independent* controllers?

IDE controller cards with >= 4 independent controllers?

by ma.. » Thu, 23 Mar 2000 04:00:00

I think I posted this before, but I'll ask again.

I'd like to try software RAID5 under Linux.

Does anyone know if there are any IDE contoller cards that have more
than two controllers on them. The more the better, but at least four
*independent* controllers (ie., not just slave drives) would be great.
There must be a market for something like this...

Thanks,
Richard

1. IDE->SCSI for CDR on offboard IDE controller

I have a HP 7200 CDRW on a Promise Ultra 100 PCI IDE controller and am
using kernel version 2.4.2. I have been following the CD-Writing HOWTO
to set up my kernel and system to use the CD writer. The HP CDRW is
found to be hdf when the system boots up. I have the necessary modules
compiled for the kernel. Then I've taken the "Testing for drivers"
script from the HOWTO & the result is given below. Apparently there must
be some funny twist due to the off board controller that is not allowing
the CD writer to be found as SCSI. I need to help to get past this
problem. The second issue is apparent below: How do I ensure that
modules are automatically loaded?

"Testing for drivers" script output:
