摘要
在虚拟网络存储系统中通常包含各种异构的存储设备节点,传统数据放置策略往往侧重于研究对系统I/O性能的影响。该文在分析了虚拟网络存储系统特点的基础上,提出了一种提高系统自适应性的均分hash算法,实验证明,该算法能有效地解决异构网络存储环境的数据放置不平衡问题,从而提高了系统的自适应性。
Abstract: There are usually many heterogeneous storage nodes in the virtual network storage systems.The traditionaldata placement policies are used to focus on the I/O performance.Based on the characters of virtual network storagesystem,this paper introduces a new share hash algorithm to improve the system self-adaptability.The experiments showthat this algorithm can resolve the imbalance problem of data placement of heterogeneous network storage,consequentlyimprove the system self-adaptability.
