I've been operating in this configuration for 6 months in two locations

I could fail over to the 2nd firewall, do the upgrade and reboot without
taking down the network. We are running on Dell 1750's w/ 2Gb ram, dual
proc, dual power supplies and 4 NIC's per server (1 wan, 1 lan, 1 sync,
1 future 2nd ISP). Probably the cheapest and most robust solution on
the market.
<aol> we too </aol> - three sets of paired machined firewall clusters.
except we're using commodity Tyan 1U servers with core2duo motherboards
with 2GB RAM. the motherboards have dual Intel 1000baseT (em0) and a
single Intel 100baseT (fxp), the latter used for sync; some also have
twin-port 1000baseT pcix cards for DMZs. I use vlans for the internal
network into cisco 3560E's (wire speed gig switch).
when they're not fiddled with they "just work".
our only problem has been "split brain" at our colo site, we think
because the separate patching to the ISPs routers is filtering traffic
which is affecting CARP, we don't get this elsewhere.
we also use pfSense as a VPN termination server, core2quad for number
crunching.
so, we're happy. memo to self: look into making another donation.

This is a small office, but still it cant go down. Im using soekris
5501 , 256 Ram 433mhz geode procs. prolly not the fastest, but small,
low power, and price is right ;)
I've used slower and had no problems, but am open to questions or concerns.
