NVIDIA UFM-SDN Appliance User Manual v4.14.1

Appendix - Switch Grouping

To facilitate the logical grouping of 1U switches into a "director-like switch" group, the UFM implements a special dedicated group of interconnected 1U switches based on a YAML configuration file. This group, which is of type "superswitch", only includes 1U switches connected to each other, with some functioning as lines and others as spines.

To access the configuration file for superswitches, users can define the path in the [SubnetManager] section of the gv.cfg file, using the variable name "super_switch_config_file_path". For instance, the path can be specified as follows: super_switch_config_file_path=/opt/ufm/files/conf/super_switches_configuration.cfg.

It is important to note that the file must be located in the /opt/ufm/files file tree, as it should be replicated between master and slave UFM servers in a high-availability configuration.

The structure of the superswitch definition should be as follows, based on the following example:

The logical grouping can be accessed under the "Groups" view, specifically listed as "SuperSwitch group" type.

On the devices view, switches that are part of the SuperSwitch group are marked with an additional icon that indicates their role in the group. The "S" icon denotes spines, while the "L" icon denotes lines.

Warning

Each SuperSwitch definition can include one or more racks where each embedded rack can include multiple leafs and spines switches.
