问题描述

  • 对于未应用QoS或自适应QoS策略的工作负载、QoS报告的延迟较高。
  • 正在从ONTAP报告TCP零窗口
  • 由于延迟较高、传递超时阈值较高、可能会出现与保持连接相关的断开连接或错误
    • 示例:由于自适应QoS和最小延迟、出现ESXi错误:
      • 由于连接问题、无法访问卷xyz。正在尝试恢复、不久将报告结果。
  • 在QoS最小延迟中心可以看到高延迟、工作负载较低

示例:
Cluster::> qos statistics volume latency show
Workload ID Latency Network Cluster Data Disk QoS Max QoS Min NVRAM
