Firewall considerations for Active File Management (AFM)

Active File Management (AFM) allows one or more IBM Spectrum Scale™ clusters, or a non-IBM Spectrum Scale NFS source, to exchange file data. File data exchange between clusters can accomplish many goals, one of which is to allow for disaster recovery.

For AFM data transfers, either NFS or NSD is used as the transport protocol.

• For port requirements of NSD, see Firewall recommendations for internal communication among nodes.
