可不使用  

适用场景

  • ONTAP 9.2 及更高版本
  • FabricPool

问题解答

是、卷设置为使用无(默认)、因为其分层策略将停止将冷数据分层到云层。

  • 将分层策略设置为无会阻止新的分层
  • 先前已移至云层的卷数据 将保留在云层 中、直到变热为止
  • 读取卷中的冷块后、这些冷块将变热、并自动移回本地层
  • 在将策略更改为"无"之前、正在分层的数据将继续分层。此大小最多可以为TLOG大小(9.13.1之前为60 GB、9.13.1中为240 GB)

追加信息

  • 强烈建议禁用集群间LIF。
    • 如果与clousd层的连接丢失、则用户或应用程序会收到一条错误消息、因为只有在云层上存在的冷块在恢复联机之前不可用
    • 此外、如果云层脱机、则冷本地层数据无法写入云层
  • 技术报告—FabricPool 最佳实践
