Hey,
Well the load balancing with the BigIP device is really very
amazing. I think what i liked most was swapping out servers when
their lease was up, through the BigIP manager I just stopped all
traffic to a server, shut it down, plugged in the new one and
turned traffic back on. It was really very easy.
The SSL stuff still gives me a headache to think about. but I
should mention I no longer work where I was, plus now I'm all .net
C# but that's a different story.
I think if I was going to do this all again I would not have
secured the bigIP unit. It was nice to buy one SSL cert for all the
servers I attached rather than one per server, but getting the SSL
sites to work properly was a headache. We also use windows file
replication where now I would go with like a pair of Dell MD1000's
mirrored for storage and just have tons of ram and cpu on the front
end units. Depends what you want to spend I guess. I think the
bigIP unit we bought was like 20 grand, i think they are cheaper
now though.
Hope I helped.
