Server Node Hostnames

The NODE column lists the hostnames of the nodes that function as I/O servers for the parallel file system being defined. The example configuration in Example 3-3 shows two parallel file systems:

• pfs0 - two server nodes: node4 and node5.

• pfs1 - two server nodes: node5 and node6.

Note that I/O server node5 is used by both pfs0 and pfs1. This is possible because node5 is attached to at least two storage devices, one of which is assigned to pfs0 and the other to pfs1.
