4 Subnet Manager – OpenSM
NOTE: This section applies to ports configured as InfiniBand only.
FlexBoot requires a Subnet Manager to be running on one of the machines in the IB network. OpenSM is part of the Mellanox OFED for Linux software package and can be used to accomplish this. Note that OpenSM may be run on the same host running the DHCP server but it is not mandatory.
For large InfiniBand clusters (> 100 nodes), it is recommended to use OpenSM caching. For further information, please refer to the Mellanox OFED User Manual.
