适用于

  • ONTAP 9

问题描述

  • 用户通过 Windows 客户端访问该文件夹下的目录和/或任何子目录可能会表现出较低的性能
  • qos statistics volume latency show 显示的输出延迟低于 1-5 毫秒
  • event log show 中没有记录到明显问题的错误
  • 这在远离存储(VPN 或 WAN)的用户中比在本地可访问的机器更明显

    • Create Request File: Windows (C) - Shortcut (3).lnk
      Create Response File: Windows (C) - Shortcut (3).lnk
      GetInfo Request SEC_INFO/SMB2_SEC_INFO_00 File: Windows (C) - Shortcut (3).lnk
