Patent number: 11900102Abstract: Systems and methods for data storage device firmware updates in a composable infrastructure are described. Recomposition of a system in a composable infrastructure may include downloading a firmware update to a data storage device, activating the firmware update in the data storage device, and receiving a reset command at the data storage device. The reset command may include a step to flush a virtual-to-physical (V2P) mapping table from a volatile memory in the data storage device to non-volatile memory devices in the data storage device. Responsive to a flag that is set and the received reset command, the data storage device may forgo the step of flushing the V2P mapping table.Type: GrantFiled: June 21, 2021Date of Patent: February 13, 2024Assignee: Western Digital Technologies, Inc.Inventors: Senthil Kumar Veluswamy, Rahul Gandhi Dhatchinamoorthy, Kumar Ranjan, Lingaraj Bal
