Data storage device firmware updates in composable infrastructure

A data storage device, comprising:

• a volatile memory;
• a plurality of non-volatile memory devices;
• a processor configured to execute instructions to:
• set, responsive to determining to decompose and recompose the data storage device, a flag indicating that flushing a virtual-to-physical (V2P) mapping table of a data storage device is unnecessary for a next reset command;
• download a firmware update to the data storage device;
• activate the firmware update in the data storage device;
• receive the next reset command, wherein reset commands normally include a step to flush the V2P mapping table from the volatile memory to at least one non-volatile memory device of the plurality of non-volatile memory devices;
• determine, prior to executing flushing of the V2P mapping table for the next reset command, whether the flag is set;
• forgo, responsive to determining that the flag is set and executing the next reset command, the step to flush the V2P mapping table to the at least one non-volatile memory device;
• and
• complete the reset command without flushing the V2P mapping table, wherein:
• the V2P mapping table is cleared from the volatile memory by a power cycle of the reset command;
• and
• a provisioning time of decomposing and recomposing the data storage device is reduced.

A data storage system, comprising:

• and
• a plurality of non-volatile memory devices;
• means for setting, responsive to determining to decompose and recompose the data storage device, a flag indicating that flushing a virtual-to-physical (V2P) mapping table of the data storage device is unnecessary for a next reset command;
• means for downloading a firmware update to the data storage device;
• means for activating the firmware update in the data storage device;
• means for receiving the next reset command at the data storage device, wherein reset commands normally include a step to flush the V2P mapping table from the volatile memory to at least one non-volatile memory device of the plurality of non-volatile memory devices in the data storage device;
