适用场景

  • ONTAP 9
  • FabricPool
  • 效率
  • 重复数据删除
  • 数据压缩
  • 数据缩减
  • 逻辑复制引擎(Logical Replication Engine、LRE)

问题解答

不可以、如果在活动文件系统(Active File System、AFS)中应用效率之前将块分层出、则该块将保留在容量层中、而不会应用效率。
注意:使用Scan-old-data 手动执行效率作业的 工作原理相同。

追加信息

  1. 文件或块已写入RW卷
  2. 未应用实时效率
    • 不支持实时效率的FAS
    • 写入工作负载较高时的AFF导致实时缺失或实时效率被禁用
    • 使用传统逻辑复制引擎(Logical Replication Engine、LRE)从SnapMirror更新DP卷、而无需通过缆线提高存储效率
  3. 在卷效率更改日志中对块进行跟踪、以便由下一个效率后台作业进行拾取、从而对其扫描/应用效率
  4. 尚未触发后台效率计划
  5. 已配置的tierer-minimum冷却天数已过、卷层扫描程序将运行
  6. 以1为单位写入的文件或块将分层到容量/云层
  7. 后台效率计划触发器
  8. 在1中写入的文件或块仍保留容量、但未应用效率功能
