mellanox网卡驱动安装和温度检查

最近配了一台自用的编译和测试主机

操作系统：ubuntu 18.04

i7-10700 + b460m迫击炮 + mellanox ConnectX-4 Lx 网卡;

这块网卡就有两个问题：

1. 开机就很烫(不管有没有ifconfig up)，手摸不得。

2. 直接Reboot之后，网卡消失了，lspci都识别不到。

降温

为了降温，特地给机箱加了暴力风扇，默认转速太吵，又通过微星的bios调低转速，噪音能接受，网卡虽然还是热，但是不会烫手了。

想通过lm-sensor监控温度失败了，永远只有CPU温度，没有别的。sensors-detect也没用。

功夫不负有心人，网上找到这么一个东西，可以看到温度。

看样子得装驱动和固件了，开干。

安装驱动

https://www.mellanox.com/products/infiniband-drivers/linux/mlnx_ofed官网下载对应的驱动 MLNX_OFED_LINUX-5.1-0.6.6.0-ubuntu18.04-x86_64.tgz

解压后

./mlnxofedinstall

直接安装，会将所需依赖库自动网络安装，而且会自动升级网卡固件

检查温度

54度还行，应该不会有烧坏的风险。

再重启一下看看，网卡还在不在

root@ckun-MS-2:~# lspci | grep Eth 01:00.0 Ethernet controller: Intel Corporation Ethernet Controller XXV710 for 25GbE SFP28 (rev 02) 01:00.1 Ethernet controller: Intel Corporation Ethernet Controller XXV710 for 25GbE SFP28 (rev 02) 03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

全部搞定。

小结

其实这个mellanox的网卡应该是给服务器用的，没有独立的散热风扇，只有一个小小的散热片，依赖服务器的暴力风扇风道散热。

相比另一个intel的X710网卡就好很多了，只是温温的，散热片也大，被动散热都足够了，台式机和服务器都好用。
