摘要：

We propose a guideline for data placement in heterogeneous distributed storage systems. heterogeneous distributed storage systems sometimes cause degradation of aggregate data throughput. The proposed guideline is that data accessed by a client should be placed equally to all servers. We evaluate a storage system configured by the proposed guideline by using sysstat and compare read/write data throughput between typical data placement and proposed data placement. Then we conclude that the proposed guideline improves the rate of aggregate data throughput while increasing the number of access streams.
