The abstract of the patent published by the U.S. Patent and Trademark Office states: “A SAS expander includes a switch core, a number of SAS expander phys coupled to the switch core, an SMP originator coupled to the switch core and an SMP receptor coupled to the switch core. In an embodiment, the SMP originator is configured to only send connection requests and the SMP receptor is configured to only receive connection requests. Program instructions stored in non-transient digital storage media include code segments detecting a new connection request, code segments determining whether the new connection request is in conflict with an existing connection request and code segments determining if there is a free destination receptor phy. In an embodiment, the free destination receptor phy is never operationally used for an origination of a connection request.“
