Connecting the Fibre Channel cables
Your MSA can be deployed into a variety of configurations, from relatively simple singlepath
configurations to more complex multipath configurations. Because there are two switches, two
HBAs, and two servers in multipath configurations, all of which use Fibre Channel cables, cable
connections must follow specific installation requirements.
NOTE: In a multipathing environment, for all servers, the first HBA should be connected to the
right-hand controller, as viewed from the front (or left-hand controller, as viewed from the back).
CAUTION: Use appropriate precautions when handling Fibre Channel cables:
• Touching the end of a Fibre Channel cable will either damage the cable or cause performance
problems, including intermittent difficulties accessing the storage.
• Whenever a Fibre Channel cable is not connected, replace the protective covers on the ends of
the cable.
• Make certain that the Fibre Channel cables are installed and supported so that no excess weight
is placed on the connectors. This prevents damage to the connector and cable. Excess cable
should be loosely coiled and tied out of the way, being careful not to coil the cable in a tight
loop with a bend radius of less than 3 inches (7.62 cm).
To connect the MSA to the SAN, use standard Fibre Channel cables.
NOTE: See the illustrations on the following pages for sample cabling configurations for a
singlepath and a multipath installation.
