Exadata上配置万兆非常简单，就是设置一下网卡，然后绑定即可
根据文档描述，万兆光口对应的接口如下：
Exadata Database Machine X5-2的eth4和eth5
不同的机器，可能接口名称不同，可以在机器上看，也可以核对文档来识别。
.
（1）Exadata上，有两个光口，是千兆万兆自适应的，但是10Gib模块需要单独购买。
（2）Exadata上，4个电口是百兆，千兆，万兆自适应的
下面的是一个例子：
例如，电口的eth0（用于连接内置的Cisco）：
[root@dm01db02 ~]# ethtool eth0
Settings for eth0:
Supported ports: [ TP ]
Supported link modes: 100baseT/Full
1000baseT/Full
10000baseT/Full
Supported pause frame use: No
Supports auto-negotiation: Yes
Advertised link modes: 100baseT/Full
1000baseT/Full
10000baseT/Full
Advertised pause frame use: No
Advertised auto-negotiation: Yes
Speed: 1000Mb/s
Duplex: Full
Port: Twisted Pair
PHYAD: 0
Transceiver: external
Auto-negotiation: on
MDI-X: Unknown
Supports Wake-on: d
Wake-on: d
Current message level: 0x00000007 (7)
drv probe link
Link detected: yes
[root@dm01db02 ~]#
连接了万兆的eth4：
[root@dm01db01 ~]# ethtool eth4
Settings for eth4:
Supported ports: [ FIBRE ]
Supported link modes: 10000baseT/Full
Supported pause frame use: No
Supports auto-negotiation: No
Advertised link modes: 10000baseT/Full
Advertised pause frame use: No
Advertised auto-negotiation: No
Speed: 10000Mb/s ------------这里显示为万兆
Duplex: Full -----------全双工
Port: Other
PHYAD: 0
Transceiver: external
Auto-negotiation: off
Supports Wake-on: d
Wake-on: d
Current message level: 0x00000007 (7)
drv probe link
Link detected: yes
[root@dm01db01 ~]#
然后设置一下IP，按照linux上绑定网卡的方法将eth4和eth5绑定即可。
万兆配置好了，测试了一下万兆的效率（还没时间做测试跨机房）：
下载了iperf安装在exadata上：

测试了一下，每秒基本上可以达到7Gb(大概7Gb/8≈700MB/s)：
