Full Bus – Full-bus mode is the only way to
access all ten disks through one
SCSI port.
– Full-bus mode allows you to use the
second SCSI port to attach
additional hosts (HP-UX only).
– Split bus allows you to mirror disks
within the disk system.
– Having fewer devices on the bus
improves bus performance.
– Split bus allows daisy chains of two
disk systems.
Address High
(split bus only)
The disk system is daisy-chained to
another disk system, which is using
the low addresses. – High addresses are used by other
devices on the bus.
– Low addresses give disks higher
priority on the bus, potentially
improving access time.
Bus
Termination The disk system is at the end of a bus.
See page 84 for details. The disk system is in the middle of a
bus. See page 84 for details.
