适用场景

  • ONTAP 9
  • FabricPool

问题解答

  • tiering-fullness-threshold 不表示存储在性能层中的最大数据量
  • tiering-fullness-threshold 指定在将数据分层到容量层之前必须使用的性能层空间百分比
  • 如果默认值为50%、则10 TB聚合只有在达到5 TB已用空间后才会开始对数据进行分层

追加信息

  • 分层策略all会忽略 tiering-fullness-threshold 、并且无论分层填量阈值如何、数据都会进行分层
  • 要修改 tiering-fullness-threshold： storage聚合object-store修改
