Driver Installation
4.1
Linux
For Linux, download and install the latest OpenFabrics Enterprise Distribution (OFED) software
package available via the Mellanox web site at: http://www.mellanox.com => Products => Soft-
ware => InfiniBand/VPI Drivers => Linux SW/Drivers => Download. This chapter describes
how to install and test the Mellanox OFED for Linux package on a single host machine with Mel-
lanox ConnectX-5 adapter hardware installed.
4.1.1 Hardware and Software Requirements
4.1.2 Downloading Mellanox OFED
Step 1.
Verify that the system has a Mellanox network adapter (HCA/NIC) installed.
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 (hexa-
decimal), 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 net-
devices by the system.
Step 2.
Download the ISO image to your host.
