适用场景

ONTAP 9

问题解答

  • ONTAP 9引入了一个全局SnapMirror限制选项 options 、可通过集群Shell中的命令进行配置。
    • 示例:

::> options -option-name replication.throttle.enable <on|off>

::> options -option-name replication.throttle.incoming.max_kbs <KBps>

::> options -option-name replication.throttle.outgoing.max_kbs <KBps>

  • ONTAP 9全局限制会影响远程和本地的Type-DP和Type-XDP SnapMirror。
  • 更改全局限制将立即生效、 而更改 每个关系的限制 将在下次传输时反映出来。
    • 注意:ONTAP中的所有复制控制均以每秒千字节为单位。
  • 如果不需要全局限制、也可以按关系执行此操作。
