Adaptive cache replacement algorithms for segmented cache

A storage system, comprising:

• a memory;
• and
• one or more processors that are operatively coupled to the memory, the one or more processors being configured to perform the operations of:
• detecting an event;
• and
• in response to the event, changing one or more replacement algorithms that are being used by the storage system, wherein changing the one or more replacement algorithms includes:
• selecting a first segment in a cache of the storage system, the first segment being serviced with a first replacement algorithm;
• generating a first signature representing a state of the storage system;
• classifying the first signature with a selection engine to identify a second replacement algorithm, the second replacement algorithm being different from the first replacement algorithm;
• and configurating the storage system to service the first segment with the second replacement algorithm.

A non-transitory computer-readable medium storing one or more processor-executable instructions, which, when executed by at least one processor of a storage system, cause the at least one processor to perform the operations of:

• detecting an event;
• and
• in response to the event, changing one or more replacement algorithms that are being used by the storage system, wherein changing the one or more replacement algorithms includes:
• selecting a first segment in a cache of the storage system, the first segment being serviced with a first replacement algorithm;
• generating a first signature representing a state of the storage system;
• classifying the first signature with a selection engine to identify a second replacement algorithm, the second replacement algorithm being different from the first replacement algorithm;
• and configurating the storage system to service the first segment with the second replacement algorithm.
