We got Y-cables from www.delta-computer.de. KA-DEC-BN21W-0B is a Tri-Link
cable with high density (88 pins) plugs. The price is about 220.- DM
Maybe the feature code and the price have changed, but I think you can get
the Y-cables from this supplier...

Hi Fabian,

I heard that someone in SuSE was working on shared-SCSI HA solutions. Does

Thanks!
