5–6 Installing the SF72 Storage Enclosure in an SF200 Storage Array
5.1.2 Where to Install the SF72 Storage Enclosure
The SF72 storage enclosures install in numerical order (Figure 5–1). For
your reference, the 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 SF200 storage array are open,
SF72 storage enclosures occupy positions 1, 2, 3, 4, 7, and 8 only.
In split-bus mode, the following drives are part of the same DSSI bus
(note that split-bus mode is supported in the single-host configuration):
1. Four drives in position 1 with the two left drives of position 3
2. Four drives in position 2 with the two right drives of position 3
3. Four drives in position 4 with the two left drives of position 8
4. Four drives in position 7 with the two right drives of position 8
All SF72 storage enclosures must be in through-bus mode when the
SF200 storage array is in the dual-host configuration:
1. Four drives in position 1
2. Four drives in position 2
3. Four drives in position 3
4. Four drives in position 4
5. Four drives in position 7
6. Four drives in position 8
