什么是更改通知?为什么数据包跟踪响应时间较长?

适用场景

  • ONTAP 9
  • Data ONTAP 7-模式
  • CIFS/SMB

问题解答

  • 响应时间是受监控文件夹更改之间的增量,但根据 SMB 规范并不需要响应时间,因此只有在实际发生更改时才会进行更新
  • 更改通知是 CIFS/SMB 的一项功能,它会向客户端发送任何文件夹更新。
    • 示例: 如果两个用户打开了相同的文件夹,而一个用户删除了一个文件,则会向已删除文件的第二个用户发送更改通知更新。
    • 这样可以节省客户端 CPU 周期,因为如果文件夹较大,用户无需刷新整个文件夹,只需更改即可
  • 仅当所监控的文件夹(例如,在共享上打开 Windows 资源管理器时)发生文件更新时,更改通知才会更新。
