Why each option
The cluster session manager (CSM) provides inter-module communication and reliable transport within ONTAP, operating transparently regardless of whether communicating modules are co-located on the same node or on different nodes.
Handling networking, NFS, and CIFS is the function of the network module, not the cluster session manager, which is concerned with internal inter-module communication, not external client protocols.
The CSM provides a standardized communication mechanism between any network or SCSI module and any data module, abstracting the physical location of those modules within the cluster.
The CSM provides reliable transport for SpinNP (Spin Network Protocol) traffic, which is the internal ONTAP messaging protocol used between cluster nodes and modules.
The CSM operates transparently whether the network or SCSI module and the data module are on the same node or on different nodes in the cluster, ensuring location-independent communication.
