Abstract
Various aspects for managing data blocks in a storage system are provided. For instance, a method may include storing, in a buffer memory, a plurality of comparison blocks, initiating a data deduplication process utilizing the plurality of comparison blocks, and performing garbage collection in conjunction with the data deduplication process. Garbage collection may include maintaining a hit count for comparison blocks of a passive set of comparison blocks in the buffer memory and deleting the passive set from the buffer memory when the hit count is decremented to a predetermined value. The hit count may be incremented and decremented based on utilization of a comparison block in the data deduplication process.
