可不使用  

适用场景

  • ONTAP 9.2及更高版本
  • FabricPool

问题解答

是、卷设置为无(默认)、因为其分层策略将停止将冷数据分层到云层。

  • 将此层策略设置为无可防止创建新的层
  • 先前已移至云层的卷数据 将一直保留在云层中 、直到变热为止
  • 读取卷中的冷块时、这些冷块将变为热块、并自动移回本地层
  • 在将策略更改为无之前正在进行分层的数据将继续分层。此大小可以高达TLOG大小(9.13.1之前为60 GB、9.13.1之前为240 GB)

追加信息

  • 强烈建议禁用集群间LIF。
    • 如果与克隆层的连接断开、则 用户或应用程序会收到错误消息、因为只有在云层上才会存在冷块、直到它恢复联机为止
    • 此外、如果云层脱机、则冷本地层数据无法写入云层
