Planning for SMB

Several steps need to be taken before the SMB service is implemented in IBM Storage Scale.

The SMB support for IBM Storage Scale allows clients to access the GPFS file system by using SMB clients. The SMB service on the protocol node provides file serving to SMB clients. Requests are routed to an SMB protocol node, typically by using DNS round robin. The SMB server on the protocol node handles these requests by issuing calls to the IBM Storage Scale file system.

Note: The SMB service is based on a clustering component CTDB. You must have the CTDB network traffic on some dedicated private network. The CTDB traffic is using the same network interface as the GPFS daemon. It can be configured or changed through the --daemon-interface option in the mmaddnode and mmchnode commands. The recommendation is to ensure that this is on a private network that is not visible outside the cluster.
