适用场景

  • ONTAP
  • NetApp 聚合加密
  • NetApp 卷加密
  • FabricPool

问题解答

ONTAP 9.6引入了NetApp聚合加密(NetApp Aggregate Encryption、NAE)、并提供了一个选项、可通过使用同一 -encrypt-with-aggr-key true交换机在同一聚合中移动卷来将现有NetApp卷加密(NetApp Volume Encryption、NVE)卷转换为NAE。  这样,加密卷就可以利用称为跨卷重复数据删除的聚合级别存储效率。

ONTAP 9.6 还引入了优化的卷移动功能,如果源聚合和目标聚合都连接到同一对象存储,则在执行卷移动时不会移动云层中的数据。

在FabricPool 配置中、如果将NVE卷移动到NAE聚合、则会使用相同的NVE密钥作为NAE唯一密钥、因此不会更改分层云数据。

  • volume move 从NVE转换到NAE期间利用优化的、必须在一个聚合之间执行操作
  • 如果 volume move 在同一聚合中使用-in执行 将NVE转换为NAE、 则云层上的所有数据将移回性能层
