The TCP/UDP port numbers listed further on in this section are used for communication on each port of the controller node (for operation of VSP One SDS Block) and storage node (that comprises VSP One SDS Block).
If a firewall installed on each network performs TCP/UDP port number filtering, set it to allow the TCP/UDP port numbers required for each type of communication.
The meaning of each indication in the "Port usage" column is as follows:
-: Not used
Client: The port number is used as a destination port.
Server: The port number is used as a receive port.
Client/Server: The port number is used as a destination port and receive port.

1. This includes management software that uses REST API. 2. The port number listed here is the default port number used when the port number is not specified in the external authentication settings. If a port number is specified, that port number will be used. 3. A port number specified for each function will be used. 4. The port number listed here is the default port number used when the destination iSNS server port number is not specified in the iSNS client function (REST API and CLI of VSP One SDS Block) settings. If a port number is specified, that port number will be used. 5. When the processes of configuring a storage cluster, adding storage nodes, and replacing storage nodes are finished, stop listening to the port and deactivate it. 6. Port numbers must be different for each storage controller. 7. When the storage node is a tiebreaker node, compute ports (iSCSI) cannot be used. |
