Multiple Fast-Wide SCSI-2
Controller Installation
When you install more than one Fast-Wide SCSI-2 Controller, the following
considerations apply:
Each Fast-Wide SCSI-2 Controller has an independent SCSI-2 channel
that supports up to seven devices.
Each SCSI-2 channel has its own set of unique SCSI IDs (from 0 to 6).
You must assign each peripheral on the bus a unique ID for that bus.
You must select the Integrated Fast-Wide SCSI-2 Controller as the
default primary controller. Use the System Configuration Utility
to select the Integrated Fast-Wide SCSI-2 Controller as the
primary controller.
Interrupt Selection
You can configure the Integrated Fast-Wide SCSI-2 Controller to use one of
four level-triggered interrupts. The Fast-Wide SCSI can share the interrupt
level chosen for the Integrated Fast-Wide SCSI-2 Controller. ISA expansion
boards cannot share the interrupt chosen for the Integrated Fast-Wide
SCSI-2 Controller.
Multiple Drive Controllers
The server supports a variety of optional hard drive controllers, including the
SMART-2 Array Controller and the Fast-Wide SCSI-2 Controller. See
Chapter 4, “Performance Advantages of ProLiant 5000 Architecture,” for
guidelines on expansion board placement.
