Q
When the QHT7040 or QHT7140 adapter is installed with the riser card, it may
prevent some or all of the other PCI expansion slots from being used. This depends
upon the form factor of the adapter and motherboard.
Run
i
path_control -i
to see information on which form factor adapter is installed.
The file

2.1.2
Cabling and Switches
InfiniPath utilizes standard, off-the-shelf InfiniBand cabling and 4X switches. The
InfiniPath interconnect is designed to work with all InfiniBand-compliant switches.
A standard InfiniBand copper cable up to a length of twenty meters is required. See
section 2.6.1 for more information. Optical fibre with optical adapters such as the
Emcore is also supported. See section 2.6.2 .
There are two options for Subnet Management in your cluster:
■
Use the Subnet Manager on one or more managed switches supplied with your
Infiniband switches.
■
Use OpenSM component of OpenFabrics.
Cabling instructions are found in this Guide in section 2.6 .
2.1.3
Software
Before installing the InfiniPath software, complete the hardware installation as
described in this chapter.
Verify that each machine in the cluster is running Linux kernel software from a
supported distribution.
See section 3.2 for information on supported distributions, associated kernels and
other software requirements.
2.1.4
