Why each option
NetApp Cluster-Mode requires InfiniBand cabling with backplane interfaces for storage interconnect and dedicated cluster switches to link cluster nodes into a single fabric.
Thunderbolt and LightPeak are not supported NetApp cluster interconnect technologies; InfiniBand or 10GbE are the valid options.
Management switches support out-of-band administration but are not a specific mandatory requirement of the Cluster-Mode solution architecture itself.
InfiniBand cabling with a backplane interface provides the high-speed, low-latency interconnect required between storage nodes in NetApp Cluster-Mode configurations.
FC cluster switches facilitate Fibre Channel SAN connectivity and are not used for the cluster interconnect fabric that Cluster-Mode requires.
Cluster switches are required hardware components that connect multiple nodes into the cluster fabric, enabling node-to-node communication and HA operation.
