Abstract: 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).

Abstract translation: 本公开涉及用于数据存储系统的高速缓存管理系统和方法。 根据各种实施例，高速缓存管理系统包括提示驱动器和优先级控制器。 提示驱动器基于由数据存储系统的主机控制器正在处理的数据传送请求截取的数据包生成指针。 优先级控制器基于由提示驱动器生成的指针来确定数据分组是否与至少第一（高）优先级或第二（正常或低）优先级关联。 不管它们是否满足阈值热商（即所选择的数据传输活动级别），高优先级数据分组都被存储在高速缓冲存储器中。

Abstract: Aspects of the disclosure pertain to a system and method for providing a flash memory cache input/output throttling mechanism based upon temperature parameters for promoting improved flash life. The mechanism restricts flash memory cache caching of inputs/outputs associated with Least Recently Used data and Most Recently Used data when a temperature of the flash memory is at or above a threshold temperature.
