Abstract:
Techniques for reducing power consumption of a storage controller are provided. An example method includes determining a back-end bandwidth of a storage system, wherein the back-end of the storage system includes a storage drive communicatively coupled to a storage controller. The method also includes determining a front-end bandwidth of the storage system, wherein the front-end of the storage system includes a front-end bus coupling the storage controller to a host. The method also includes computing a target back-end memory bandwidth based on the back-end bandwidth and computing a target front-end memory bandwidth based on the front-end bandwidth. The method also includes reducing power consumption of the storage controller by reducing 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.
