Abstract
In one embodiment, a system includes a cache storage device and a processor and logic integrated with and/or executable by the processor. The logic is configured to select a cache block descriptor (CBD) from amongst a plurality of CBDs, the selected CBD including indications of being fragmented in the cache storage device. The logic is also configured to determine whether to defragment the selected CBD. Moreover, the logic is configured to defragment the selected CBD on the cache storage device in response to a decision to defragment the selected CBD.
