Linux Driver Installation | NVIDIA ConnectX-5 InfiniBand/Ethernet Socket Direct Adapter Cards User Manual

This section describes how to install and test the NVIDIA OFED for Linux package on a single host machine with Mellanox ConnectX-5 adapter hardware installed.

Prerequisites

Requirements	Description
Platforms	A server platform with a ConnectX-5 adapter card installed.
Required Disk Space for Installation	1GB
Operating System	Linux operating system. For the list of supported operating system distributions and kernels, please refer to the MLNX_OFED Release Notes file.
Installer Privileges	The installation requires administrator (root) privileges on the target machine.

Downloading NVIDIA OFED

Verify that the system has a NVIDIA network adapter installed.
The following example shows a system with an installed NVIDIA adapter card:
```
[root@mftqa-009 ~]# lspci |grep mellanox -i
05:00.0 Infiniband controller: Mellanox Technologies MT27800 Family [ConnectX-5]
05:00.1 Infiniband controller: Mellanox Technologies MT27800 Family [ConnectX-5]
82:00.0 Infiniband controller: Mellanox Technologies MT27800 Family [ConnectX-5]
82:00.1 Infiniband controller: Mellanox Technologies MT27800 Family [ConnectX-5]
```
In the output example above, the first two rows indicate that one card is installed in a PCI slot with PCI Bus address 05 (hexadecimal), PCI Device number 00 and PCI Function number 0 and 1. The other card is installed in a PCI slot with PCI Bus address 82 (hexadecimal), PCI Device number 00 and PCI Function number 0 and 1.

Since the two PCIe cards are installed in two PCIe slots, each card gets a unique PCI Bus and Device number. Each of the PCIe x8 busses sees two network ports; in effect, the two 100Gb/s physical ports of the ConnectX-5 Socket Direct Adapter are viewed as four netdevices by the system.

For Linux driver installation, please refer to NVIDIA DOCA Installation Guide for Linux.
