FabricPool

解答

在 FabricPool 配置中,如果使用分层策略 snapshot-only 和 auto 访问卷,则分层冷数据将从云 / 容量层移至性能层。  对于采用 " 全部 " 分层策略的卷,所有数据将直接从云 / 容量层提供。 

但是,如果使用的性能层为 70% 或以上,则在访问任何分层策略时,云层中的数据不会移至性能层,并且将触发以下 EMS :

Aggregate aggr2_ssd: Current available space in the performance tier is below 30%%. Data migration from the capacity tier to the performance tier is stopped.

 

因此,所有数据将直接从容量 / 云层提供,您可能会遇到 IO 访问延迟。增加聚合上的可用空间,以便在访问数据时将数据从容量层移至性能层。
