Which Dual-Channel SCSI PCI-X Controller ?

Hello NG,

after making the experience that my PCI-Controller (SYM53C896) didn't
work in the PCI-X-Slot of my new Mainboard, i'm looking for a Dual-
Channel-U160 (or U320) Controller for PCI-X. I need a dual-channel
solution, because i have internal U320-Disks and external UW-Dat und U-
SCSI-Scanner. So i need at least 3 connections of which one is only
single-ended-scsi and 2 connections for LVD.
Till now I found only the Adaptec 39160 and 39320 Controllers. Any
further suggestions ? The board is a ASUS P5WDG2WS-Pro.

with kind regardes, Stephan Weber
