智能网络磁盘集群负载平衡研究

Research on load balancing of intelligent network disk cluster

智能网络磁盘(IND)是一种存储体系结构的新构思,IND集群是一种海量存储的新途径,为维护系统的自动负载平衡,用基于访问频数的动态调整和适时迁移策略相结合,精心设计算法,合理布局数据,使系统高效稳定运行,长期实践表明,这种负载平衡的灵活调度策略,对IND集群存储系统的实现是必要而有利的,对高性能计算的海量存储尤为重要。

Intelligent Network Disk（IND）is a novel idea of storage architecture.IND cluster is a new way for mass storage.In order to maintain automatic load balancing in system,a schedule strategy with dynamic regulation based on access frequency and migration in time is used.With careful design of algorithm and rational distribution of data,the cluster system has run efficiently and stably for a long time.Practical experience shows that the flexible schedule strategy for load balancing is necessary and beneficial to implementation of IND cluster storage system,especially to mass storage for high performance computing.
