状态信息

适用场景

  • ONTAP 9
  • CIFS
  • 访问基础枚举(ABE)

问题描述

当性能问题与ABE相关时、可能会出现以下部分或全部症状:

  • 已在一个或多个CIFS共享上启用Abe (此共享必须存在)
  • 在启用ABE的情况下、CIFS共享上的延迟非常高、可能为数百毫秒
  • 查看 qos statistics volume latency show 命令会在 Data 列下显示大多数延迟
  • 查看perfstat章节"QoS工作负载报告"可显示工作负载在CPU_WAFL_exoned上的等待时间、可能为数百毫秒
  • 此共享可由许多用户访问
  • 共享的文件数量较多(数百万个文件)
