Why each option
Cluster management and IP-based data interfaces (CIFS, NFS) are designed with failover and online migration capabilities to ensure high availability and operational flexibility across cluster nodes. These logical interfaces can seamlessly move between nodes to maintain service continuity.
Cluster interfaces are internal communication links within the cluster and are not intended for external client failover or online migration to a different node.
Cluster management logical interfaces (LIFs) provide external access to manage the cluster and are configured for failover and migration to ensure continuous management accessibility.
While iSCSI interfaces can support failover, Fibre Channel (FC) interfaces typically have different high availability mechanisms tied to paths, and 'online migration to a different node' is not a primary feature in the same manner as for IP data LIFs.
Data logical interfaces (LIFs) for CIFS and NFS are specifically designed to support online migration and automatic failover between nodes to maintain continuous data access during node failures or maintenance.
Node-management interfaces are typically local to a specific node and are not designed to failover or migrate to other nodes in the cluster to maintain management access across the entire cluster.
