Patent number: 11593287Abstract: A port configuration migration system includes a primary I/O module connected to a server device via a secondary I/O module. A fabric manager system maps a virtual interface to a first downlink port on the primary I/O module that is connected to the secondary I/O module, with the virtual interface providing a virtual direct connection to the server device. The fabric manager system then configures the virtual interface with communication configuration information for the server device such that communications received via the first downlink port are transmitted using the virtual interface. The fabric manager system then receives a discovery communication from the server device via a second downlink port on the primary I/O module that is connected to the secondary I/O module, and remaps the virtual interface to the second downlink port such that communications received via the second downlink port are transmitted using the virtual interface.Type: GrantFiled: October 20, 2021Date of Patent: February 28, 2023Assignee: Dell Products L.P.Inventors: Pawan Kumar Singal, Balaji Rajagopalan, Ning Zhuang, Joyas Joseph, Joseph Lasalle White
