Abstract :
Storage QoS methodology has been extensively mentioned in large-scale storage systems. Since storage resources tend to be heterogeneous and dynamic changed, efficient storage states capturing becomes essential. In this paper we propose a novel capturing and preserving mechanism, called change state capture (CSC). CSC can capture the changed state when storage provider QoS modified. The changed event can trigger the broker module to reorganize the storage resources to meet this change. The experimental results show that CSC can achieve better performance than existing periodic scanning algorithm in terms of efficiency.
