Thermal requirement
If you have a IBM Storage Scale System Utility Node, you might be required to set the thermal mode
of the system to a setting other than the default setting, depending on your system, adapter, and cable
type.
Cables
For this host bus adapter (HBA), IBM offers Active Optical Cables (AOC) cables up to 30m. QSFP112-
based transceivers are included on each end of these cables.
Cable matrix
The NDR cables that are listed in the below table support connecting an NDR two port 200 Gb HBA.
