适用场景

  • ONTAP 9
  • 两个40G端口构成一个LACP

问题解答

  • 两个40G端口的吞吐量限制为10Gb/秒、因为理论上每个40G端口限制为5Gb/秒
  • 此LIF报告的吞吐量高于12 GB/秒

这是预期行为:

  • 在全双工模式下、发送方可以发送数据、也可以同时接收数据。它是双向同时进行的双向通信。

  • 从System Manager报告的吞吐量是输入和输出的总和、在全双工模式下、输入和输出均可达到10GB/秒因此理论限制为20GB/秒

追加信息

  • 请参见 全双工带宽的问题描述
  • AIQ PAS节点视图中显示的LIF吞吐量也是输入和输出的总和
