适用场景

  • ONTAP 9
  • SnapMirror
  • 块复制引擎(BRE)
  • 具有存储效率的逻辑复制(Logical Replication with Storage效率、LRSE)
  • 卷移动

问题描述

  •  由于复制引擎限制、SnapMirror传输期间吞吐量较低
  •   首先确认已将以下各项作为潜在问题加以消除
    • 避免一次运行过多的SnapMirror传输
    • 分散SnapMirror传输以减少影响
    • 在用户工作负载较低且CPU活动较低时启动SnapMirror传输
    • 检查是否正在对SnapMirror使用全局限制机制
    • 如果复制流量通过WAN传输、则可以为这些 SnapMirror策略启用网络压缩以提高性能
      • 注:如果CPU利用率已经很高、请勿使用网络压缩
