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( AFS )中应用效率之前分层块,则该块将保留在容量层中而不应用效率。

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 AFF 会导致实时未命中或实时效率被禁用
    • 使用传统逻辑复制引擎( Logical Replication Engine , LRE )从 SnapMirror 更新 DP 卷,而无需通过线缆提高存储效率
  3. 块会在卷效率更改日志中进行跟踪,以供下一个效率后台作业选择,以便对其扫描 / 应用效率
  4. 尚未触发后台效率计划
  5. 已配置分层最小冷却天数,并且卷分层扫描程序已运行
  6. 以 1 为格式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. 以 1 格式写入的文件或块仍保留容量,而不会应用效率
