File storage resources are accessed through NAS protocols, such as NFS and SMB. A NAS server can provide access to a file system using all NAS protocols simultaneously if configured for multiprotocol access.
A single NAS server uses compute resources from only one node of the appliance. It is recommended to create at least two NAS servers (one on each node) so that resources from both nodes contribute to file performance.
NAS servers can be manually moved from one node to the other. This action can be done to balance the workload if one node is busier than the other. All file systems that are served by a given NAS server move with the NAS server to the other node.
