适用场景

  • ONTAP 9
  • 支持FabricPool或Cloud Tiering的系统

问题解答

  • 层扫描程序使用大多数可用的后台CPU周期。
  • 这些周期实际上与备用CPU周期相同、但用于确保数据有效分层。
  • 这是正常现象、不应用于考虑CPU利用率较高的情况。
  • 由于扫描程序数量和优先级的增加、ONTAP 9 11.1增加了CPU。
  • 从 9.13.0 开始，分层扫描器将在活动文件系统 (AFS) 中的任何数据分层后自动启动重定向扫描。
  • ONTAP 9.11.1 将分层扫描仪的数量从 10 增加到 20，如CONTAP-64247中所述，适用于所有系统， 而不仅仅是 AFF 。
