A Cache Management Scheme for Object-based Storage

Abstract

This paper presents a cache management scheme for object-based storage, which consists of three main aspects. First, the cache update policy is proposed. The strategy considers the overall cache as a pool, consistency and accuracy of updating is ensured through the locking mechanism, while using Bloom Filter combined with the updated time series to achieve updating simplification. Secondly, the cache replacement strategy is introduced which achieving the cache replacement policy using cache spanning tree combined with cache stack. Finally, cache management model is proposed based on energy consumption. Experimental results show that the proposed cache management scheme can improve the efficiency of cache management in object-based storage system, while reducing energy consumption of cache management.
