适用场景

4节点MetroCluster

问题解答

  • 一个4节点MetroCluster将使用大约1/4的驱动器进行存储
    • MetroCluster存储支持4个节点、而非MetroCluster HA对仅支持2个节点
      • 这样可将可用驱动器减少一半
    • MetroCluster存储使用镜像、这种镜像将使用两倍的磁盘、而不会为聚合提供额外空间
      • 这样可将可用驱动器减少一半
  • 由于每个节点可用于存储的驱动器较少、因此奇偶校验驱动器的百分比高于非MetroCluster HA对
  • MetroCluster系统已启用聚合快照以考虑镜像
    • 默认快照预留为5%、不能用于数据存储
