Hum, it will depend on the LVS setup since my main concern is network load repartition, that can do the trick with one VIP and LVS setup with DR from the HAProxies (it's just a replacement of RR DNS). The session initialization sequence (well the first packet) will still be handled just be one box. Sound better than RR DNS from a failover point of view. -- Jérôme Benoit aka fraggle La Météo du Net - http://grenouille.com OpenPGP Key ID : 9FE9161D Key fingerprint : 9CA4 0249 AF57 A35B 34B3 AC15 FAA0 CB50 9FE9 161D
