Single viewfs namespace between two IBM Storage Scale file systems

You can get a single viewfs namespace joining two IBM Storage Scale file systems from different clusters or from the same cluster.

Irrespective of the mode that you select, configure one HDFS transparency cluster for each IBM Storage Scale file system (see Hadoop cluster planning, Installing, and Configuring), and then join the two HDFS transparency clusters together.

Federate two IBM Storage Scale file systems from different clusters.

Federate two IBM Storage Scale file systems from the same cluster.

To join two file systems from the same cluster, select nodes that can provide HDFS transparency services for the first file system and the second file system separately.
