Abstract
SAS expanders are commonly used within a SAS network topology to allow multiple disk drives (targets) to connect to multiple host devices (initiators). A connection between an initiator and a target is setup inside an expander on the pathway between the initiator and the target. A source device sends a connection request message called an open address frame using in-band signaling. The expander processes the open address frame and forwards an modified open address frame to the next expander in the path or to the final destination device.
