4 Expander A/B — Four single-RAID hosts direct connection to a 24-drive

sled

In this configuration, the four hosts are connected to the storage sled and

the 24 hard-drives are grouped into four zones. Expander chip A controls

zones 0 and 1 and expander chip B controls zones 2 and 3. See Figure 1-13.

This cabling option supports RAID cards only and allows you to manually

update the expander firmware on both expander chips one at a time. You

will need to switch the cables in the mini-SAS A1, A2 and mini-SAS B1, B2

connectors to update the second expander chip.
