I would suggest that you look at switch or router based solutions instead of a
PC based solution such as the Big IP unit. You might want to join the Discussion
Group on the website Http://www.loadbalancing.net and ask some questions there.
The group members have a lot of experience with many higher end load blanacing
I hope I have been of some help.
