We use a couple Dell 1550's with heartbeat for high availability
for directors... we've had a few scrapes along the way, which
mostly have been my own fault setting up the real web servers to
avoid the arp problem... beyond that, we're very happy with the
solution now that those problems are ironed out... and it's
helped us have a lower-cost solution to sell customers...
On the other hand, one of our customers has a Cisco (forget what
it is) for hardware load balancing because they wanted our
solution, but didn't trust the lvs to do the load balancing...
from what I've seen, it has basically all the same capabilities,
only less flexability in configuring (or doing it easily), at a
higher cost... they had the same kind of arp issues, and some
other issues with customized software that didn't want to work
with the cisco unit (4 months later they're still fighting with
that), but we had it tested and working with lvs before they
decided they wanted to go with cisco...
I just today setup my 4th web server setup with lvs for a new
customer (director + backup director + 6 web servers)... this
one's a big customer, and we apparently signed for 99.5% uptime!
