Microsemi Storage Solutions, Inc., Aliso Viejo, CA, has been assigned a patent (9,866,658) developed by Yi, Cheng, Vancouver, Canada, Liao, Heng, Belcarra, Canada, and Leung, Calvin, Burnaby, Canada, for a “method and apparatus for SAS open address frame processing in SAS expanders.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “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.”

The patent application was filed on October 19, 2016 (15/297,625).
