Systems and methods for cache load balancing by reclaimable block migration are described. In some embodiments, a computer system may include a processor; and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution by the processor, cause the computer system to: maintain a first list of reclaimable blocks that reside in a first caching device and a first advertised age for the oldest reclaimable block of the first list; maintain a second list of reclaimable blocks that reside in a second caching device and a second advertised age for the oldest reclaimable block of the second list; determine that the second advertised age is older than the first advertised age; and cause the oldest reclaimable block on the first list to be migrated from the first caching device to the second caching device.

Cache load balancing by reclaimable block migration

In one embodiment, a computer system includes a cache having one or more memories and a metadata service. The metadata service is able to receive requests for data stored in the cache from a first client and from a second client. The metadata service is further able to determine whether the performance of the cache would be improved by relocating the data stored in the cache. The metadata service is further operable to relocate the data stored in the cache when such relocation would improve the performance of the cache.
