Recommended host interface connection
The recommended host interface connection uses bonded interfaces for a public network-only architecture.
For a Fusion Data Foundation Multus architecture using only the public network (recommended for most users), the same nodes from the example above can be used. eth0, eth1, eth2, and eth4 would be bonded as bond1 and tagged as vlan220. This architecture ensures that storage nodes have additional available bandwidth for replication and recovery needed by Fusion Data Foundation Ceph OSDs. vlan220 is be used for Fusion Data Foundation configuration. However, many variations of valid environments exist.

There is no requirement to dedicate extra public network bandwidth to storage nodes, though this is beneficial. eth4 and eth5 can be omitted from storage nodes entirely to dedicate the same bandwidth to both worker and storage nodes. This design has been commonly seen in customer environments.
Alternatively, eth2 and eth3 can be higher-throughput interfaces on storage nodes (for example, 10Gbps on worker nodes and 25Gbps on storage nodes). This allows for more storage node bandwidth while still using only two interfaces on storage nodes.
