Abstract
In one embodiment, a system includes a back-end storage device, a cache storage device, and a processor and logic integrated with and/or executable by the processor. The logic is configured to store data to the cache storage device using fine block descriptors (FBDs) configured for fine-grained mapping of variable-size cache allocations. The logic is also configured to store data to the back-end storage device using cache block descriptors (CBDs) configured for coarse-grained mapping of large blocks of data. At least some FBDs are smaller in size than any of the CBDs, and all FBDs are equal to or smaller in size than any of the CBDs.
