适用于

ONTAP 9

回答

  • ONTAP 9 引入了一个全局 SnapMirror 限制选项,可通过集群外壳中的 options 命令进行配置。
    • 示例:

::> options -option-name replication*

::> 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 全局限流会影响远程和本地 Type-DP 及 Type-XDP SnapMirrors。
  • 更改全局限流会立即生效,而更改每个关系的限流会从下一次传输开始生效。
    • 注意:ONTAP 中的所有复制限制均以KiloBytes每秒为单位。
  • 如果不希望在全局范围内进行限制,也可以基于每个关系进行限制。
