The documentation is a hair unclear here, I guess.
You can build a 100 node GFS cluster. In the case of the documentation
above, it is referring to just the failover component (not related to
GFS).
That is, you can...
* build a 100 node cluster
* mount GFS on 100 nodes
* Access files from all 100 nodes
* start the "service manager" ("Cluster Manager") portion on 16
