description A cache storage system indexing method is provided that indexes a data address in a cache storage system based on a data fingerprint of the cached data, wherein the data fingerprint is generated by a deduplication fingerprint function used for referencing deduplication of data in the cache storage system. A computer-implemented method of data operations to a cache storage system is also provided including: obtaining a data fingerprint for the data of the data operation, either by applying a deduplication fingerprinting function to data of a write operation or by accessing deduplication metadata for a read operation to obtain the data fingerprint generated by using a deduplication fingerprinting function used for deduplication of data in the cache storage system; and using an indexing service to the cache storage system having an address schema based on the data fingerprints of the data.
