I don't mean to be picky, but isn't the SCSI cable(s) still a single point of
failure?

558.3 | Multi-Bus Failover Mode | DECWET::LEES | Will, NTSG DECwest, Seattle | Tue Jan 28 1997 15:47 | 12 |
| Yes, if termination is broken anywhere on the Scsi cable potentially both
systems could hang.
One solution to this is a special cabling configuration of the RAID subsystem
called "Multi-bus failover mode". In this configuration there are two disjoint
Scsi buses, each between a host and the RAID subsystem. Each one is
electrically separate; a break in one does not effect the other.
Support for MBFM is dependent on a RAID firmware change that is not expected
until Summer.

I didn't think there was (currently-or in the near future) any support for
this under Windows NT (with, or without Clusters). Am I mistaken about this?
