Students received good experiences in basic configuration of servers in system administration
classes, but a Beowulf cluster illustrated the demands of managing a LAN. Software configurations
change over time by upgrading software packages, introducing new ones, removing old
ones, and tweaking the existing packages. Every machine in a cluster must be able to work with
the other machines. Maintaining the software on a cluster consists of administrative work multiplied
by ‘n’ nodes - each of which is potentially dependent on other nodes. Students learned the
skills necessary to identify the needs of the users of the cluster (and the needs of the cluster itself)
and successfully fulfilled those needs
