HPRD: High Performance Tiered Replica Distribution in Cluster Storage System

The cluster system exists as a variety of different machines. There are Nodes with high performance and nodes with lower performance. The distribution of data on each machine and I / O are determined by the equalization of load balancing. According to the traditional way of clustering data distribution, high performance node performance generally can't fulfill full potential. In this way, the lower performance nodes will become bottleneck. To address this issue we carried out some research and propose a High Performance Tiered Replica Distribution (HPRD) a way of the replica data distribution in the cluster storage system. HPRD can fulfill full high-performance nodes potential in the aspect of the performance benefits and high performance nodes can share more high-performance I/O load. Such performance bottleneck will not exist in the lower performance nodes. It can improve the performance of cluster system and the cluster system resource Utilization rate.It also can reduce inefficient use of resources.
