The split-bus configuration shown in the preceding figure assigns half the IDs from the
RAID and the expansion unit to channel 0, and the other half to channel 2. The
“SINGLE-BUS CONF” port is a channel 2 expansion port in a split-bus configuration.

configuration are shown in the following figures.
ID6 and ID7 are reserved and are not available for drive IDs.
The IDs are also displayed on the lower inside edge of the chassis. These IDs are
automatically assigned and appear in RAID controller status tables.
