Abstract: 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.

Abstract: Systems and methods for predicting whether a nonvolatile memory block is likely capable of being securely erased to be eligible for composing into another composable infrastructure are described. A management module receives a secure-erase command to erase at least one nonvolatile memory block, determines health parameters of the nonvolatile memory block, calculates a failure index based on the health parameters, and, based on the failure index, either securely erases the block of memory or retires the nonvolatile memory block.

Abstract: A data storage device coupled to a controller. The controller is configured to determine whether a request to perform a data transfer operation has been received and determine whether a request to perform a garbage collection operation is necessary during the data transfer operation. The controller generates an extended logical-to-physical table (L2P) including information for the data transfer operation in response to determining the request to perform the data transfer operation has been received and the request to perform the garbage collection operation is necessary, transmits the extended L2P table to one or more peer data storage devices, and performs the garbage collection operation after transmitting the extended L2P table to the one or more peer data storage devices.
