When I call a company and ask for an accountant, I get the companies accountant, when I ask for an account manager, that's what I get. That's what titles are, and that's why they are important. I know the type of person I need to talk to, but I don't know who it is I need to talk to. Its why standardization in titles is good, when I go digging through my pile of business cards looking for the Network Engineer/Architect at company X, I'll probably not notice a custom/weird title. It does not define you, it does not make you any less or more important, it does however answer the question of "Who is responsible for..." which I believe to be extremely valuable. Then again, I might be weird. ~J
RE: Experiences with A10 AX series Load Balancers?
The boxes do alright at low load levels. They do not have an asic tech like the F5s so choke on large amounts of traffic. Management is a bit immature and you will find yourself having to use the CLI and the Gui to accomplish most advanced tasks. When we put them head to head A10 AX3200 vs F5 6400 ltm (note: 6400 was what we were looking to replace) Test: 1000 concurrent users from Gomez's Networks Loadtesting platform hitting as fast as the requests would close, going through our standard vip config on the f5, and the A10 engineering teams 3 best efforts to beat that config that balanced between two Identical Dell 1950 servers serving a php page that responded with a random number (to avoid caching). The 6400 we used was in production at the time, and was older so we were expecting to get blown away, see the results here: F5 - Peaked 160k completed transactions a minute sustained for 10 minutes, 0 errors, 112ms average transaction response time A10 - Held 60k completed transactions a minute sustained for 10 minutes, 0 errors, 360ms average transaction response time If anyone is interested in the graphs I think I can still pull them out of gomez.

Anyone knows the answer? I can't speak to what they are *supposed* to do, but my experience is that things can be overheard. Last summer I discovered that my Comcast cable had two premium digital channels I hadn't ordered. One was showing soft porn, and while I was sitting there pondering this, it began to fast forward. Not surprisingly, it was fast forwarding over the boring parts and then watching the naughty bits at normal speed. I can only assume that one of the neighboring houses has video-on-demand.
