Search for the "localnode" feature of the LVS. You can install the Loadbalancer on the application machines. No "waste" or hardware. So my suggestion: - 5 machines with the application - on two of there machines install the cluster software and the ldirectord. Have the ldirectord resource controlled by the cluster. You get an application cluster with 5 machines and a HA loadbalancer. Greetings, -- Dr. Michael Schwartzkopff Guardinistr. 63 81375 München Tel: (0163) 172 50 98
