适用场景

  • ONTAP 9.6及更高版本
  • FabricPool
  • CVO
  • Amazon Web Services S3 (AWS S3)

问题解答

ONTAP 9.6引入了经过优化的卷移动功能、如果源聚合和目标聚合连接到同一云层分段(对象存储)、则在执行卷移动时不会移动云层中的数据。

但是、很少有情况会使卷移动变得未经优化、即云层中的所有数据都会复制到性能层、然后根据分层策略复制回云层。

FabricPool卷移动将在下一个位置未进行优化:

  1. 已将此卷移动到同一聚合中、以便从NetApp卷加密转换为NetApp聚合加密
  2. 源聚合和目标聚合中使用的加密类型不同、或者正在重新设置密钥
  3. 使用generate目标密钥选项执行卷移动
  4. 卷是卷克隆或克隆的父卷
  5. 对于使用AWS S3的配置、如果源FabricPool是在ONTAP 9.5之前的版本上创建的、而目标FabricPool是在ONTAP 9.5及更高版本上创建的、则这些FabricPools之间的卷移动将不会进行优化。
  6. 在卷移动期间、已更改此层策略。下表显示了卷移动期间的层策略更改结果:
