Port Protocol Configuration
Ports 1 to 8 are pre-configured to Ethernet. Ports 9 to 36 are pre-configured to InfiniBand. Ports 1
to 8 can be configured to support 13 10GbE SFP+ data streams. See Section 4.2 on page 51 for
the split-able ports. See the Mellanox MLNX-OS user manual for instructions on port re-config-
uration.
A future software release will support each port to be manually configured to be either Infiniband
or Ethernet. Specific ports can be split from 40 GbE to four times 10GbE. All ports can then be
configured to optimize your network.
2.6.7
Port Speed Configuration
These QSFP+ ports can be manually configured to run at speeds ranging from 1GbE to 56 GbE.
To change the port speed configuration use the GUI, or use the CLI and go to the interface con-
figuration mode, then use the command “speed”. See the Mellanox MLNX-OS user manual for
instructions on port speed re-configuration.
