Multiple Expander Example
Path Redundancy Application
To increase the number of devices within a topology, multiple LSISASx12
expanders can be cascaded into edge expander device sets as
illustrated in
external support components including a reference clock and a Serial
EEPROM device. A single serial EEPROM can provide unique
configurations to up to four LSISASx12 expanders.
Figure 1.2
Path redundancy can be provided by utilizing dual-ported SAS drives.
