Optimized Inline Deduplication

A computing system comprising:

• a storage controller coupled to at least one storage device, wherein the storage controller is configured for:
• receiving a request to write data to a storage system;
• generating, based on the request, a hash value associated with the request to write data;
• determining whether the generated hash value matches an entry in a deduplication data structure;
• and
• responsive to determining that the generated hash value matches an entry in a deduplication data structure, discarding the data and updating the entry in the deduplication data structure.

A non-transitory computer readable storage medium storing program instruction executable by a processor for:

• receiving a request to write data to a storage system;
• generating, based on the request, a hash value associated with the request to write data;
• determining whether the generated hash value matches an entry in a deduplication data structure;
• and
• responsive to determining that the generated hash value matches an entry in a deduplication data structure, discarding the data and updating the entry in the deduplication data structure.
