Storage system bandwidth determination

A storage system comprising:

• a storage controller;
• a back end that comprises a storage drive communicatively coupled to the storage controller;
• a front end comprising a front-end bus communicatively coupled to the storage controller;
• and
• a non-transitory computer-readable medium comprising instructions executable by the storage controller to:
• determine a back-end bandwidth of the storage system;
• determine a front-end bandwidth of the storage system;
• compute a target back-end memory bandwidth based on the back-end bandwidth, including instructions to:
• compute a bandwidth multiplier based on caching statistics recorded for the storage system during the processing of storage requests;
• and
• multiply the back-end bandwidth by the bandwidth multiplier;
• compute a target front-end memory bandwidth based on the front-end bandwidth;
• and
• reduce a clock frequency of a memory device of the storage controller based on the greater of the target back-end memory bandwidth and the target front-end memory bandwidth.

A tangible, non-transitory, computer-readable medium comprising instructions executable by a processor to:

• determine a back-end bandwidth of the storage system;
• determine a front-end bandwidth of the storage system;
• compute a target back-end memory bandwidth based on the back-end bandwidth, including instructions to:
• compute a bandwidth multiplier based on caching statistics recorded for the storage system during the processing of storage requests;
• and
• multiply the back-end bandwidth by the bandwidth multiplier;
• compute a target front-end memory bandwidth based on the front-end bandwidth;
• and
• reduce a clock frequency of a memory device of the storage controller based on the greater of the target back-end memory bandwidth and the target front-end memory bandwidth.
