Using Dual-Bus I/O Modules in the Disk
Enclosures
Figure 2-2 shows UltraSCSI cables installed between a controller enclosure
and three disk enclosures. When three or fewer disk enclosures are present in a
storage subsystem, use one dual-bus I/O module in each disk enclosure to
support up to 14 disk drives in each disk enclosure. Using single-bus I/O
modules limits you to 12 disk drives per disk enclosure.
