A Cache Design of Load Balancing System for Object-Based Storage

In design of the object-based storage system, cache design of the server becomes an important guarantee for improving service quality. This paper presents a cache design of load balancing system 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 design model is proposed based on energy consumption. Experimental results show that the proposed cache design can improve the efficiency of cache operation in object-based storage system, while reducing energy consumption of cache operation.
