Each NAS server supports up to 50 production and 10 backup interfaces. Production interfaces are used for client connectivity over FTP, SFTP, NFS, and SMB. Backup interfaces support NFS-only access, which can be used for backup purposes.
NAS server interfaces must be created on a bond for high availability purposes. The bond can be either a Link Aggregation or Fail-Safe Network. With a bond, link loss on a single port does not impact connectivity to the NAS server.
Ping from one of the NAS server interfaces can be used for troubleshooting purposes. The system designates one interface as the preferred interface, which is used for outgoing communication to external services. Also, custom host and network routes can be configured on a per-interface basis.
