The Question is:
Is there a maximun number of DIFFERENT (types of) scsi controllers set for the
DS10/466?
The rumor is 2 scsi controllers total?
The system options does specify a maximum of 2 controllers kzpcm or a maximum
of 2 controllers kzpba, but there is no word, if o total number of 4
controllers (2*kzpcm, 2*kzpba) are allowed.
There is some need to run old 8 bit scsi devices and some 16 bit devices, so
more controllers might be a useful thing.
----------
Be advised: The old kzpaa does work together with one kzpcm, even it is not
specified anywhere. But thats only 2 controllers, shooting for more...
The Answer is :
The available PCI slots (and particularly available PCI slots with
interrupts, if required) are the usual limits here. Not the variety
of PCI controllers involved.
For specific system support limits and for specific supported
controllers, please see the QuickSpecs for the particular system.
Please contact your hardware services organization for assistance
with reconfiguring the system hardware.
Mixing older SCSI and newer SCSI devices on the same SCSI bus requires
great care, and incorrect configurations can easily lead to subtle
problems. Certain mixtures of SCSI devices are simply incompatible,
even within the same SCSI generation. It is often simply best to
replace older SCSI devices with more recent or even current-generation
SCSI devices. Older and specialized SCSI devices can sometimes be
best banished to an older VAX or Alpha system, and clustered or
otherwise accessed remotely.
Please realize that SCSI also requires you to occasionally sacrifice
a rubber chicken or other similar trinket for correct bus operation.
