Abstract
A SAS (Serial Attached SCSI or Serial Attached Small Computer System Interface) switch includes a master SAS expander and a multitude of slave expanders connected to the master SAS expander. Each slave expander has a distinct SAS address. The slave expanders are not directly connected to one another and communicate through the master expander. The SAS switch has a pair of SAS wide ports each having a multitude of SAS links each associated with one of the slave expanders. The slave expanders are configured to route SAS traffic in accordance with routing tables established by the master SAS expander. The master SAS expander is not directly connected to either of the SAS wide ports.
