[hobbit] Fail over?

[T.J. Yang]

Isn't a proxy is another SPF (Single point of failure) ?

That sounds like an interesting idea to use squid to load balance between the two servers. I need to do something similar in our lab and been trying to figure out the best way to do it.

I believe you could use something like a proxy (Squid maybe?) for clients to connect to and then use one or the other.  I'm not familiar at all with squid itself so I may be completely off, but a load balancer does sound like an option.

I was thinking of using Sun Cluster(hb on Solaris) or HeartBeat(hb on Linux) but
then how can I configure the Cluster solution to failover from one site(Florida) to another(NewYork) ?


I believe this setup is the most simple failover solution at the only expense of extra
network bandwidth usgage to the secondary hb server.
