-----Ursprungligt meddelande----- Fran: owner-freebsd-cluster@freebsd.org Hi there can you suggest a good HA solution based on freeBSD servers, like the following. Load balancing TCP+UDP on virtual ip + failover on the routers. ( net ) | | | ---------- | switch | ---------- / \ / \ ---------- ---------- failover | active backup router | | router | ---------- ---------- load-balance \ / \ VIP / ---------- | switch | ---------- / \ / \ ---------- ---------- | server1 | | server2 | ---------- ---------- real servers This solution make no real sense, why have HA servers when you do not have HA switches?, you are likely to set yourself up for disappointment is all, use seperate switches as well in order to get a real HA solution. Also in order to give more accurate answer we would need to know what applications/services you will be providing, there is a huge difference between all TCP and only wanting HTTP/HTTPS failover and so on. regards Matt
