• Use of a second controller shelf: By convention, the first controller shelf (C1)
would use S1-S5; the second controller shelf (C2) would use S6, S8, and S9.
This permits two subsystems, one with up to 24-28 3½-inch SBB devices (in
the front), and the other with 18-21 3½-inch SBB devices (in the rear).
• SW300-series cabinet shelves: The SW500-series cabinets do not accept
SW300-series cabinet integrated controller/storage shelves.
Refer to the StorageWorks SW500-Series Cabinet Installation and User’s Guide
for more details.
Figure 3–5 shows the loading sequence for storage and controller shelves when
TZ8xx-series tape devices are installed in an SW500-series cabinet. Refer to
the StorageWorks SW500-Series Cabinet Installation and User’s Guide for new
loading sequence illustrations for cabinets using 4 GB or larger disk drives.
