More Information
Summary:A system and method of cache monitoring in storage systems includes storing storage blocks in a cache memory. Each of the storage blocks is associated with status indicators. As requests are received at the cache memory, the requests are processed and the status indicators associated with the storage blocks are updated in response to the processing of the requests. One or more storage blocks are selected for eviction when a storage block limit is reached. As ones of the selected one or more storage blocks are evicted from the cache memory, the block counters are updated based on the status indicators associated with the evicted storage blocks. Each of the block counters is associated with a corresponding combination of the status indicators. Caching statistics are periodically updated based on the block counters.
