Hi - sorry for the late reply!

In the UK we (the JANET Web Cache Service [1]) are using Linux Virtual
Server [2] to load balance two (soon to be three) clusters of quite
busy Squids. Overall our server farms are shipping some 70 million
proxy HTTP requests/day at peak loadings, but this isn't entirely load
balanced using LVS yet.

At the moment the code we use for load balancing and monitoring is
entirely homegrown, but it's likely that we'll move to RedHat's
Piranha [3] clustering (new in RedHat 6.2 beta [4]). At the moment
we're using IP tunnelling rather than NAT, and server status
monitoring is initiated by the real server rather than the director,
so our model isn't quite compatible with what Piranha is doing - it
only supports NAT, and has the director polling the real servers.

Time to pull the hacking gloves on... :-)

Cheers,

Martin
