A system comprising:

• a memory;
• and
• a processor operatively coupled to the memory, the processor to:
• in view of a write request pertaining to a first object, determine, based on a first signature of the first object, whether an index of a storage system comprises an existing object record pertaining to the first object, wherein each of a plurality of entries of the index corresponds to a respective portion of a storage pool comprising a plurality of storage devices;
• and
• in response to determining that the index of the storage system does not include an existing object record pertaining to the first signature, create a first object record in the index comprising the first signature and a reference count, wherein two or more of the plurality of entries of the index correspond to a plurality of hashes of the first signature, and wherein, to create the first object record, the processor is further to:
• store the first signature of the first object in a first entry of the plurality of the entries of the index corresponding to a first hash of the first signature;
• wherein the processor is further to:
• in response to determining that the index of the storage system includes an existing object record pertaining to the first signature, update a reference count associated with the first object, wherein the exiting object record pertaining to the first signature comprises the reference count associated with the first object.

A non-transitory machine-readable storage medium including instructions that, when accessed by a processor, cause the processor to:

• in view of a write request pertaining to a first object, determine, based on a first signature of the first object, whether an index of a storage system comprises an existing object record pertaining to the first object, wherein each of a plurality of entries of the index corresponds to a respective portion of a storage pool comprising a plurality of storage devices;
• and
• in response to determining that the index of the storage system does not include an existing object record pertaining to the first signature, create a first object record in the index comprising the first signature and a reference count, wherein two or more of the plurality of entries of the index correspond to a plurality of hashes of the first signature, and wherein, to create the first object record, the processor is further to:
• store the first signature of the first object in a first entry of the plurality of the entries of the index corresponding to a first hash of the first signature, wherein the first signature of the first object is a hash of at least a portion of content of the first object;
• in response to determining that the index of the storage system includes an existing object record pertaining to the first signature, update a reference count associated with the first object, wherein the exiting object record pertaining to the first signature comprises the reference count.
