适用场景

  • ONTAP 9.x
  • SnapMirror源节点具有扇出SnapMirror关系

问题描述

  • SnapMirror源节点具有一个或多个速度较慢的扇出SnapMirror关系、以及来自同一源节点的其他速度较快的扇出SnapMirror关系。
  • 在某些情况下、一个或多个速度较慢的SnapMirror关系会限制通过速度较快的SnapMirror关系实现的吞吐量速率。
    • 如果较慢的SnapMirror镜像中止或以其他方式处于空闲状态、则速度较快的Snapshot关系将恢复到预期速度。
    • 注:
      • 只有当从同一源节点同时传输的SnapMirors速度较慢时、此知识库文章才适用。
      • 在这种情况下、如果要运行较慢的SnapMirors已中止或未传输、则会以预期速度运行快速SnapMirors。
  • 例如、假设一个SnapMirror源节点具有一个集群间SnapMirror关系、该关系通过WAN链路实现的吞吐量最多为15 MB/秒
    • 同一个SnapMirror源节点还具有一个集群内SnapMirror关系、该关系通过10Gbps集群互连进行复制、从而实现100 MB/秒的吞吐量
    • 传输速度较慢的集群间SnapMirror时、速度较快的集群内SnapMirror会减慢至~15-20MB/秒
    • 中止速度较慢的集群间SnapMirror时、速度较快的集群内SnapMirror会恢复到预期的100MB/s吞吐量。
