昨天刚发现新购的 Dell PowerEdge R710 服务器上配的 Intel Ethernet Server Adapter X520-T2 万兆网卡居然在 VMware ESXi 里找不到，查了一下有 VMware 的官方驱动，不过需要另外安装。

到 VMWare 官方网站下载网卡驱动，然后上传到 VMware ESXi 服务器的一个临时目录 /tmp（用 scp 上传的话当然首先要开启 VMware ESXi 的 SSH 服务）：

$ scp ixgbe-3.4.23-458775.zip root@192.168.2.8:/tmp

ssh 登陆到 VMware ESXi 服务器后解压驱动包，解压后会得到后缀为 .vib 的驱动文件：

$ ssh root@192.168.2.8

使用 esxcli 命令行安装 vib 驱动并检查是否安装成功：

/tmp # esxcli software vib install -v /tmp/net-ixgbe-3.4.23-1OEM.500.0.0.406165.x86_64.vib

安装成功后重启 VMware ESXi，然后查看一下 Intel Corporation 10-Gigabit 网卡驱动是否能被正确识别出来：

使用 vSphere Client 客户端登入 VMware ESXi 以后，进入 Configuration 页面的 Network Adapters 应该会看到新安装的 vmnic4, vmnic5, vmnic6, vmnic7 4个网卡接口了，或者直接在 ESXi 上用命令行界面：
