It depends upon the type of load balancing you need. LVS does Layer 3 balancing, so it knows nothing about the protocols flowing through it. If you only need balancing for a specific app type (ie. web app), then you can get more nuanced. We tried to implement LVS for a web farm, and had some major issues with sticky sessions. We did more research and settled on apache to terminate SSL and haproxy for the balancing. We're using 2 of the Dell R610s with 1 CPU each for the SSL and haproxy, and they don't even break a sweat. We thought about using nginx as the SSL frontend, but went with apache to standardize on one httpd. Haproxy for this application is just fantastic. We implemented an HA cluster of these using pulse/corosync, which is a full-blow clustering solution. The failover works flawlessly. _______________________________________________ Discuss mailing list Discuss@lopsa.org http://lopsa.org/cgi-bin/mailman/listinfo/discuss This list provided by the League of Professional System Administrators http://lopsa.org/
