Abstract:
The present disclosure provides methods, systems, and non-transitory computer readable media for optimizing garbage collection operations. An exemplary method comprises receiving an update operation on data to be stored in a host-managed drive in a data storage system; inserting the update operation in a local storage of a host of the data storage system; marking one or more obsolete versions of the data in the local storage; and performing, by a translation layer corresponding to the host-managed drive, a garbage collection operation on the host-managed drive, wherein the garbage collection operation removes the one or more obsolete versions of the data marked in the local storage according to the update operation, and the translation layer comprises address mapping information between the host and the host-managed drive.
