Re: [K12OSN] OT: Routing issue



Ah yes, the "experts"...reminds me of MCSE's....

If your test phase would permit it, I can attest to the functionality of CentOS 5's load balancer.  It's actually pretty darned good and even compares favourably to F5's BigIP box.  Doesn't take that much of an expert to set up, just some reading.  My setup, which includes two load balancers in failover configuration, was done in three days, and that includes the study/learning time, since I'd never actually set up a load balancer in my life before.  Now, I can do it in less than an hour; if I add failover, that's an hour and a half.  Oh, and it's a lot cheaper, too.  :-)
