问题解答

e0S接口是较新的FAS和AFF存储系统中的接口。

从概念上讲、e0S是节点上的ONTAP接口、用于与其服务处理器(Service Processor、SP)或基板管理控制器(BASEboard Management Controller、BMC)进行内部通信。

  • 它会在192.0.2.x子网中自动配置硬编码的IP地址。
  • 在大多数平台上、它用于在SP/BMC和ONTAP内部直接进行SP/BMC固件更新和错误状况报告
  • 在许多基于BMC的平台上、此内部子网也用于硬件辅助存储故障转移(因为两个节点的e0S接口和BMC可以在内部相互识别)。
详细信息
  • ONTAP HA配对节点和两个BMC之间存在专用和内部以太网交换子网:
    • ONTAP接口: e0S
    • BMC接口: eth0 eth1,具体取决于平台型号
  • 对所有接口使用静态分配的IP地址的子网192.0.2.0/24
  • 硬件辅助故障转移、ONTAP <-> BMC通信 (IPMI)和BMC固件更新等功能通过此专用网络执行
  • [1] 这些平台的启动介质更换将使用 system node restore-backup 命令的e0S IP地址
  • 无法配置硬件辅助接管—它使用静态分配的地址(请参见下表)

IP寻址是静态的、会在所有相关以太网接口上自动配置:

控制器 e0S地址/掩码 BMC地址/掩码
A 192.0.2.84/24 192.0.2.81/24
B 192.0.2.85/24 192.0.2.82/24
