Abstract: Described herein is a system and method for an efficient cache warm-up. The system and method may copy data blocks from a primary storage device to a cache memory device. The system and method may identify a subset of data blocks stored on the primary storage device as candidate data blocks for copying to the cache memory device during a cache warm-up period. A cost effectiveness for copying the candidate data blocks to the cache memory device may be determined. In some embodiments, the cost effectiveness may be calculated based on one or more latency values associated with the primary storage device and the cache memory device. The candidate data blocks may be copied to the cache memory device based on the cost effectiveness.
