Never used them for email processing. But work quite well for
load balancing. Easy to use, fast, quite a bit of features. I played
around a bit with LVS is it? about a year ago. The one killer feature
it didn't have that I require(d) was NAT'ing the traffic so I could
bounce connections back onto the same network. I didn't see any such
ability in LVS at the time anyways, maybe it's there now.
Well, they had one that had amazing throughput with guarantees of not
losing any emails once the box has accepted them for delivery.
My network switches run linux too(I think some commercial embedded
flavor), as does my storage array(SSH banner says Debian at least).
Neither give access to a native linux shell though. Shit, even my
new Phillips TV runs linux. Crazy seems like almost everything does
these days.
Haha. Yes, I know that more and more appliances are getting Linux based
control systems but I am certainly very interested in how they got a box
running a 2.4 version of Linux to perform like what I saw. I had
upgraded the mailservers of the company to get a bit more performance by
moving to 2.6 but F5 runs a 2.4.x Linux kernel and has a single box
perform better than a cluster of the mailservers I upgraded to 2.6?!
What do they have in those boxes? ASICs doing smtp and dns that somehow
create zero network latency? What patches do they have in their souped
up sccp version?
