Installing the ISO Image
Mellanox provides prebuilt binaries for all recent Linux client distributions. Mellanox OpenFabrics
Enterprise Distribution (OFED) is delivered as an ISO image.
Note: Even though a Mellanox HCA is used in this example, Qlogic HCAs are also supported.
The ISO image contains both source code and binary RPMs for selected Linux distributions, as well
as the installation script: mlnxofedinstall.
Mount the iso image file and execute ./mlnxofedinstall.
For example:
mount -o rw,loop/work/MLNX_OFED_LINUX-1.4-sles10_sp1_sp2.iso /mnt
cd /mnt
./mlnxofedinstall
