下载了mellanox官网上的MLNX_OFED_LINUX-3.3-1.0.4.0-ubuntu14.04-x86_64，自己的系统是ubuntu 14.04.3 ，内核是3.19.0.安装后出现如下问题：
Attempting to perform Firmware update...

Link Width: x4 ( WARNING - device supports x8 )
PCI Link Speed: 5GT/s
执行命令ibstat查看，网卡的stat为Down
求教什么原因

1. https://www.mellanox.com/

2. 重點是 網卡上面的晶片 品牌與型號
2-1. 把下面指令 複製 貼進終端機 執行
sudo lshw -numeric -class network
把結果全部直接 選取/複製/貼上來

admin1@admin:~$ sudo lshw -numeric -class network

运行结果如上，我机器上现在是两块网卡一块以太网卡一块HCA卡，想要驱动HCA卡
网卡S/N：MT1146X03829

1. http://pciids.sourceforge.net/v2.2/pci.ids
8086 Intel Corporation
15b7 Ethernet Connection (2) I219-LM

2. 從這個網址下載 e1000e-3.3.3.tar.gz 來安裝看看
https://sourceforge.net/projects/e1000/ ... ble/3.3.3/
Initial support for the following devices:
* Ethernet Connection (4) I219-LM
* Ethernet Connection (4) I219-V
* Ethernet Connection (5) I219-LM
* Ethernet Connection (5) I219-V

第一个网址打不开， e1000e-3.3.3.tar.gz 我下载了，并安装了。看了一下似乎和infiniband那张卡没什么关系吧，sudo lshw -numeric -class network显示的是我那张已经配置的以太网网卡的信息吧，而未驱动成功的infiniband网卡没有显示，是这样吗？

把下面指令 複製 貼進終端機 執行
1. uname -a
2. sudo lspci -knn
把結果全部直接 選取/複製/貼上來
看看 有沒有偵測到硬件
如果是 U 卡 請再貼文

sudo cat /usr/share/misc/pci.ids
這個檔案 也有一份名單

2-2. 詳見

有成功也有失敗案例

3. sudo lspci -knn 有 表示 硬件偵測到了
sudo lshw -numeric -class network 沒有 表示沒有被驅動

4. 最新驅動

Mellanox EN Driver for Linux
MLNX_EN Download Center

Ubuntu 14.04

5. 使用說明書
http://www.mellanox.com/related-docs/us ... manual.pdf
www.mellanox.com
ConnectX-2 EN Dual Port SFP+ Ethernet
Adapter Card User Manual

IOMMU是针对amd的，我的是intel 的i7,所以这个行不通啊。
然后我安装了最新的驱动，应该是通过了，没有之前的错误。

是写入nterface时出的问题吗？还是驱动还未成功？

1. 看看你的 Intel i7 型號 是否包含在裡面
1-1. https://en.wikipedia.org/wiki/List_of_I ... g_hardware
List of IOMMU-supporting hardware
1-2. https://en.wikipedia.org/wiki/List_of_I ... ntel_based
Intel based
List of Intel and Intel-based hardware that supports VT-d (Intel Virtualization Technology for Directed I/O)

2. 把下面指令 複製 貼進終端機 執行
2-1. sudo lshw -numeric -class network
2-2. sudo ifconfig -a
2-3. sudo cat /etc/network/interfaces
2-4. sudo cat /etc/NetworkManager/NetworkManager.conf
2-5. sudo nmcli dev status
把結果全部直接 選取/複製/貼上來
上面指令 主要要看看 網卡驅動是否已經合適驅動

我的是i7 6700,列表里面包含的是i7 6700K

但是目前沒有資料流使用 ib0

是參考哪裡的資料
請提供網址

求教代表什么？
是否和我现在机器上还使用另一张以太网卡上网有关？

了解了，现在我ping 172.1.1.201能够ping通，但是172.1.1.203就不行了，这是什么原因？
