System and Method of Caching Hinted Data

摘要

The disclosure is directed to a system and method of cache management for a data storage system. According to various embodiments, the cache management system includes a hinting driver and a priority controller. The hinting driver generates pointers based upon data packets intercepted from data transfer requests being processed by a host controller of the data storage system. The priority controller determines whether the data packets are associated with at least a first (high) priority level or a second (normal or low) priority level based upon the pointers generated by the hinting driver. High priority data packets are stored in cache memory regardless of whether they satisfy a threshold heat quotient (i.e. a selected level of data transfer activity).

主权项

1. A system for cache management, comprising:
a hinting driver configured to receive data packets of a data transfer request being processed by a host controller in communication with one or more storage devices, and further configured to generate pointers based upon the data packets; and a priority controller configured to receive the pointers generated by the hinting driver, further configured to determine, based upon the pointers, whether the data packets are associated with a first priority level or a second priority level, and further configured to store the data packets in a cache memory when the data packets are associated with the first priority level, the first priority level being a higher priority than the second priority level.
