Abstract
A storage proxy loads cache lines with data from a storage device. Storage access requests are received from an initiator and directed to the storage device. The storage proxy provides the data from the cache lines in response to cache hits on the cache lines, and provides the data from the storage device in response to cache misses on the cache lines. Hit access times are identified for the cache lines in response to the cache hits and miss access times are identified for the storage device in response to cache misses. Data in the cache lines is updated with data from the storage device based on the hit access times and the miss access times associated with the cache lines.
