适用场景

  • BlueXP
  • Cloud Volumes ONTAP (CVO)
  • Amazon Web Services (AWS)
  • Google Cloud Platform (GCP)

问题解答

对于为扩展聚合的活动文件系统而添加的每个磁盘、会向配对节点添加一个大小相同的磁盘以实现同步镜像。下面我们来举例说明一下: 
  • BlueXP用户尝试 向聚合添加两个8 TiB GP2磁盘。用户尝试购买磁盘时、BlueXP会显示以下通知:

  • 扩展聚合时,磁盘数称为 4,但配置的大小仅包含 2个磁盘 (不包括为聚合元数据和性能预留的空间):

  • 之所以出现上述反映、是因为总磁盘数还会考虑添加到配对节点以进行同步镜像的磁盘。

 

 

追加信息

  • 需要注意的是、虽然 系统中增加了32 TiB的容量(由4个磁盘 计算)、并且云提供商会对所有4个磁盘收费、但NetApp许可证限制仅计入16 TiB。
  • AWS中的存储限制
