The phrase "High Performance Computing equipment" makes me think of infiniband, fibre all over the place etc. Hadoop doesn't need that, it runs well on standard pc hardware - i.e. no special hardware you couldn't find in a standard pc. That doesn't mean you should run it on pcs that are being used for other things though. I found that hadoop ran ok on fairly old hardware - a load of old power-pc macs (running linux) churned through some jobs quickly, and I've actually run it on people's office machines during the nights (not on Windows). I did end up having to add an extra switch in for the part of the network that was only 100 mbps to get the throughput though. Of course ideally you would be running it on a rack of 1u servers, but that's still normally standard pc hardware.
