Craig,
All of the literature I have seen clearly states that only the N-Class
supports dual port cards under MPE. This is true of both the HVD and LVD
SCSI Host Bus Adapters. The new A5159B documentation does not even mention
supported MPE servers but I am assuming that it is the same as the A5159A.
See (Watch the wrap):
A5159A:

As for the new Ultra160 HBA this is from the 7.5 communicator:
A6829A Dual Port Ultra160 SCSI (PCI bus) Adapter Card. (N-Class Only) This
card plugs into a PCI Bus on the system and presents two (2) independent
SCSI Buses to the outside world. These SCSI Buses are capable of operating
in either LVD or SE Mode. This determination is made automatically by the
card based upon the devices and termination present on the Bus; there is no
software control for this feature. Each SCSI bus must be independently
terminated. Depending upon the cables/connectors being used this would
typically be either a High Density (HD) 68-pin LVD/SE terminator such as
C2364A or, for Very High Density (VHDCI) 68-pin LVD/SE cables, a C2370A.

Let Peace be the maxim by which we act because we will Peace to become a
