Help me spec a pair of new Dell servers for BM 3.8, running forward/reverse
proxy, firewall, caching and C2S VPN. I would like to cluster them for
fault tolerance, although IIRC I'll need to configure the VPN on both with
separate addresses. Need to go back and read up on that again.

Right now I'm looking at two 2850 servers with single 3.2gb CPUs, 4gb ram,
PERC 4dc controllers with 4 drives each, 2 mirrored on one channel for SYS,
logging, etc. and separate spindles on the other channel for cache.

That's all pretty old school though, so have things changed in the last
couple years? Is there a better way to do things now?

Suggestions welcome!
