A module was implemented to balance the disk space usage on a Hadoop Distributed File System cluster when some data nodes became full or when new empty nodes joined the cluster. 在某些数据节点已满或者新的空节点加入集群时,实现一个模块来平衡Hadoop分布式文件系统集群上的磁盘空间使用情况。
According to experience, spreading these locations to all disks on each node can achieve disk I/ O balance and therefore greatly improve the disk I/ O performance. 根据个人经验,把这些位置分散在每个节点上的所有磁盘上可以实现磁盘I/O平衡,因此会显著改进磁盘I/O性能。
CABVW keeps the balance between disk I/ O bandwidth and the caching system by dynamically adjusting the values of merging-cache cost and splitting-cache cost. 该算法通过动态调整拆分代价和合并代价的阈值,实现了磁盘带宽和缓存的负载平衡。
If this situation occurred, the balance will enable the disk in a relatively short time period, thin mill. 若这种现象接连发生,可使平衡盘在较短的时间内被磨薄。
Based on the balance disk structure and operational principle, the measure, analysis and control system was designed in the paper. 基于平衡盘的结构和工作原理,设计了相应的测量、分析和控制系统。

Balance of the balance disk is dynamic, the pump rotor in a balanced position for the axial pulse before and after. 平衡盘的平衡状态是动态的,泵的转子在某一平衡位置会前后作轴向脉动。
The main reasons affecting the performance of disk I/ O are disk competition, too frequent I/ O and the configuration and management of data blocks. Making all available disks equally balance I/ O may reduce the disk access time. 影响磁盘I/O性能的主要原因有磁盘竞争、I/O次数过多和数据块空间的分配管理,使所有可用的磁盘均匀地平衡I/O,可以减少磁盘存取的时间;
