Abstract
A hardware search structure quickly determines the status of cache lines associated with a large disk array and at the same time reduces the amount of memory space needed for tracking the status. The search structure is configurable in hardware to different cache line sizes and different primary and secondary index sizes. A maintenance feature invalidates state record entries based both on their time stamps and on associated usage statistics.
