METHODS AND SYSTEMS FOR USING PREDICTIVE CACHE STATISTICS IN A STORAGE SYSTEM

摘要

Method and systems for a storage system are provided. Simulated cache blocks of a cache system are tracked using cache metadata while performing a workload having a plurality of storage operations. The cache metadata is segmented, each segment corresponding to a cache size. Predictive statistics are determined for each cache size using a corresponding segment of the cache metadata. The predictive statistics are used to determine an amount of data that is written for each cache size within certain duration. The process then determines if each cache size provides an endurance level after executing a certain number of write operations, where the endurance level indicates a desired life-cycle for each cache size.

1. A machine implemented method, comprising:
tracking simulated cache blocks of a cache system using cache metadata while performing a workload having a plurality of storage operations, where the cache metadata is segmented, each segment corresponding to a cache size; determining predictive statistics for each cache size using a corresponding segment of the cache metadata; using the predictive statistics to determine an amount of data that is written for each cache size within a certain duration; and determining an endurance level that each cache size provides after executing a certain number of write operations, where the endurance level indicates a desired life-cycle for each cache size.
