适用场景

  • ONTAP 9.1 - 9.5P3
  • 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 关系会限制较快的 SnapMirror 关系所实现的吞吐量。
    • 当速度较慢的 SnapMirrors 中止或闲置时,速度较快的 SnapMirror 关系将恢复到预期速度。
    • 注:
      • 只有当快 SnapMirrors 同时从同一源节点传输较慢的 SnapMirrors 而受到限制时,此知识库才适用。
      • 在这些情况下,如果较慢的 SnapMirror已 中止或无法传输,则快照 SnapMirror将 以预期速度运行。
  • 例如,假设 SnapMirror 源节点具有一个集群间 SnapMirror 关系,通过 WAN 链路实现的吞吐量最多为 15 MB/ 秒
    • 同一个 SnapMirror 源节点还具有一个通过 10 Gbps 集群互连进行复制的集群内 SnapMirror 关系,从而实现 100 MB/ 秒的吞吐量 
    • 传输速度较慢的集群间 SnapMirror 时,集群内 SnapMirror 速度较快,会减慢至 ~15-20MB/ 秒
    • 中止速度较慢的集群间 SnapMirror 时,集群内 SnapMirror 会更快地恢复到预期的 100 MB/ 秒吞吐量。
