While off topic, but how do you guys measure your IO to disk?

A couple of weeks ago, I was asked if our Hobbit system at work could handle monitoring of one more customer. Of course, I said - no problem.
Well, there was one gotcha: This customer has 1100+ servers that need to be monitored. Which means my Hobbit installation is about to double in the number of hosts monitored. Hmm ...
This will be interesting to watch. I am fairly confident that Hobbit can handle it, with one exception: The disks on my Hobbit server will be overloaded. It already spends about 50% of it's time in I/O wait, so doubling the number of hosts with cpu/memory/disk etc. graphs will probably crash it.
Strange that I/O seem to be an issue for you. What kind of system do you run
the hobbit server on?
I have ~3300 rrd files updated here on a blade with an old 40 Gig 5400 2,5"
hard drive and it is almost idle.
