Firewall considerations for using IBM Spectrum Archive with IBM Storage Scale

The IBM Spectrum Archive software is installed on a node or a group of nodes in an IBM Storage Scale cluster.

This requires that each IBM Spectrum Archive node can communicate with the rest of the cluster using the ports required for basic GPFS cluster operations. For more information, see Firewall recommendations for internal communication among nodes. In addition to this, IBM Spectrum Archive communicates with RPC. For RPC related port requirements, see Firewall recommendations for protocol access.

IBM Spectrum Archive can connect to tape drives using a SAN or a direct connection.
