Abstract
A method and apparatus are provided for implementing resilient connectivity in a Serial Attached SCSI (SAS) domain. A first edge expander is connected to a first port of a plurality of SAS devices for enabling communications between each of the plurality of SAS devices through the first edge expander. A second edge expander is connected to a second port of the plurality of SAS devices for enabling communications between each of the plurality of SAS devices through the second edge expander. A subtractive routing port of each of the first edge expander and the second edge expander is connected together for enabling communications between each of the plurality of SAS devices via the first ports and the second ports of the plurality of SAS devices.
