iSCSI is appropriate and supported. NFS is a common setup as well, and on certain hardware it can perform better than iSCSI. If HA is a requirement, just don't forget to do things like get a SAN with redundant storage processors and redundant connections to all the hosts. --joshua. _______________________________________________ Discuss mailing list [email protected] http://lopsa.org/cgi-bin/mailman/listinfo/discuss This list provided by the League of Professional System Administrators http://lopsa.org/
