5.2 Where to Install the SF3x Storage Enclosure
Storage enclosures must be installed in the DECarray cabinet in ascending
numerical order (see Figure 5–1). Storage enclosure positions are numbered
from 1 to 8 on the left and right chassis side rails. These numbers are visible
only when the front or rear doors of the DECarray cabinet are open.
SF3x storage enclosures can only occupy positions 1, 2, 3, 4, 7, and 8.
In split-bus mode the ISEs occupying the left-side slots share a DSSI bus, and
the ISEs occupying the right-side slots a different DSSI bus. This is true for
the front six ISEs and the rear six ISEs. Therefore, a fully-populated SF3x
enclosure in split-bus mode will have four DSSI buses, each with three ISEs
connected to it. Four DSSI adapter ports are required for each SF3x storage
enclosure.
