At the university, we use PRTG for all sorts of monitoring. I'd been working with porting our disk monitoring we currently do for Windows servers in perfmon alerts to PRTG. That seems to work fine and PRTG seemed like a good choice for monitoring Linux partitions seeing as we really hadn't had a good solutions for it yet.

Warning: Rant content

So the talk of Lefthand math ties nicely into my topic for today. And yes, I’m going to rant. A number of years ago, we bought a SAN solution from Lefthand networks. It performed well. We were able to house Exchange and some file server stuff on it and it was just fine. We started down the path of virtualizing servers. We bought three more of the modules. At that point, they had discontinued the 150 model that we were used to. We smarted a bit from that, since we had negotiated future pricing on those units but we went ahead and bought 3 160 models.
