You might want something like:
/->FC6-1--\
INTERNET ---> CSU/DSU---->LVS--> --> ProCurve Switch
\->FC6-1--/
This way, if your FC6-1 fails, LVS wil notice it and send all your clients
through the second machine, that's to say FC6-2. So then, you'll have an HA
enviroment, and no one will realised which gateway they are using to connect
to the ProCurve switch, or whatever you want to set up behind those FC6. In
addition, by using LVS and Keepalive you could have a load balancer in the
LVS machine and setting up a round robin balancer. This is not the point
here, but it's just another possiblity to take advantaje of that LVS machine,
only if you really think you need it ;-)
Hope this helps
All the best.
