适用场景

  • FabricPool
  • ONTAP 9.8 及更高版本
  • 非活动数据报告( IDR )

问题解答

  • 在ONTAP 9.7之前、只 tiering-minimum-cooling-days 能为FabricPool 聚合上托管的卷设置per-FlexVol字段、这些卷的分层策略设置为 autosnapshot-only
    • 在ONTAP 9.8中、可以使用此参数计算冷数据的节省量、并可从2天调整为183天
  • 从ONTAP 9.8开始、使用分层策略的FabricPool 聚合上托管的卷 snapshot-only 不会报告冷数据
    • 对于非FabricPool聚合和分层策略上托管的卷 snapshot-only、报告的冷数据适用于快照、而不是活动文件系统(Active File System、AFS)
    • 在ONTAP 9.8之前、将同时报告AFS和快照冷数据。
  • 9.8还使用温度敏感型存储效率

追加信息

要查看 FabricPool 聚合上每个卷的冷数据,请运行命令 volume show-footprint
