My testing setup consists of a cheap Ubuntu 8.10 Server, hosting some WD Raptor disks, a Dell 5224 Gigabit switch, and my own workstation (running Ubuntu 8.10) which hosts VirtualBox virtual machines. All storage is abstracted across the network with whichever protocol I'm testing, the best of which will be used within the demonstration.
There is a certain amount of competition on the day, thus I believe that the judges and potential employers present will need to be 'caught' before I can properly explain my project. As we all know that humans respond well to shiny things, I thought that the readers of Slashdot might know of a relevant, disk-intensive benchmark (running on any guest platform that VirtualBox supports) that also provides an eye-catching element to aid me with hooking-in the judges. Any suggestions?
