Abstract
According to some embodiments, delta checkpoints are provided for a non-volatile memory indirection table to facilitate a recovery process after a power loss event.
Claims15
A method, comprising:
- maintaining an indirection table associated with sized portions of a non-volatile memory, the indirection table including a mapping of logical-to-physical addresses;
- and
- storing delta information in the non-volatile memory, the delta information being associated with updates to the indirection table in connection with a plurality of the sized portions of the non-volatile memory.
An apparatus, comprising:
- an indirection table structure associated with sized portions of a non-volatile memory, the indirection table including a mapping of logical-to-physical addresses;
- and
- a non-volatile memory to store delta information, the delta information being associated with updates to the indirection table in connection with a plurality of the sized portions of the non-volatile memory.
