When to use Multus

Use Multus for Fusion Data Foundation when you need the following:

Improved latency - Multus with Fusion Data Foundation always improves latency. Use host interfaces at near-host network speeds and bypass OpenShift’s software-defined Pod network. You can also perform Linux per interface level tuning for each interface.

Improved bandwidth - Dedicated interfaces for Fusion Data Foundation client data traffic and internal data traffic. These dedicated interfaces reserve full bandwidth.

Improved security - Multus isolates storage network traffic from application network traffic for added security. Bandwidth or performance might not be isolated when networks share an interface, however, you can use QoS or traffic shaping to prioritize bandwidth on shared interfaces.
