Learn how to construct and deconstruct a simple multicluster of System x™ and System p™ computers using the General Parallel File System (GPFS). You can remotely add an existing GPFS cluster to another cluster. See how to mount a file system from the remote cluster using the GPFS secure communication protocol.more
