3.5.7 How to configure wide port checker
This feature is applicable for SAS drives instead of SATA drives. If there is no connection
with any active SAS initiator by checking all wide ports, AIC Expander Controller stops all
attached SAS drives to save power consumption of SAS drives. Otherwise, AIC Expander
Controller starts all attached SAS drives to provide drive access service to any active SAS
initiator. The same setting should be applied to HUB and EGDE.
