The storage network is an optional network that is only required if using an external Netapp Trident cluster as a storage backend.
The storage network provides connectivity between all nodes in the StarlingX cluster (controller nodes and worker nodes) and the Netapp Trident cluster.
For the most part, the storage network shares the design considerations applicable to the internal management network.
It can be implemented using a 10 Gb Ethernet interface.
It can be VLAN-tagged, enabling it to share an interface with the management or OAM network.
It can own the entire IP address range on the subnet, or a specified range.
It supports dynamic or static IP address assignment.
