Throughput Servicing Time Allocation of Hybrid Storage System Based on Client Grouping Mechanism

The fair division theory has emerged as a promising approach for the throughput allocation of hybrid storage system. While most of them cause the unfair allocation of the throughput servicing time due to taking no consideration of clients' request IO latencies. We propose one Servicing time allocation method based on the client grouping mechanism(STCG), STCG establishes fair allocation policies based on clients' workload weights, which can achieve a fair throughput servicing time allocation, and can maximize the resource utilization. The experimental result shows that STCG's allocation enjoys fair properties in each client group, and compared with the method proposd recently, STCG can improve the resource utilization about 12%-330%.
