IB Network

The IB network features low latency and high bandwidth and is used in a number of High Performance Computing (HPC) projects. It uses the 100 Gbit/s Mellanox IB NIC, dedicated IB switch, and controller software UFM to ensure network communication and management, and uses the Partition Key to isolate IB networks of different tenants (similar to VLANs in the Ethernet).

Unified Fabric Manager (UFM) is the IB switch controller of the IB network based on OpenSM software and provides northbound service ports. It is deployed in active/standby mode.
