The controller operates with a Model 2100 UltraSCSI controller enclosure combined
with either Model 4214R (maximum of two) or Model 4254 (maximum of one) disk
enclosures. Physical drives are assigned SCSI target ID numbers 0 through 5 and 8
through 13 (SCSI target IDs 6 and 7 are reserved for the controllers, and SCSI target
IDs 14 and 15 are not supported). Figure 2–2 shows the addresses for each device using
two Model 4214R disk enclosure shelves in a single-bus configuration. Figure 2–3 shows
the addresses for each drive using a single Model 4254 disk enclosure shelf in a dual-bus
configuration.
