Range-based cache control system and method |
摘要 |
The present invention relates to disk drive having a cache control system that generates scan results that permit response to a host command using existing cached data having a logical block address (LBA) range that overlaps a host command LBA range. The cache control system forms variable length segments of memory clusters in a cache memory for caching disk data in contiguous LBA ranges. The cached LBA ranges are scanned for segments having LBA ranges overlapping with an LBA range of a host command.
