Back when I worked for Dell, I was assigned a special task: test a datacenter. I do not work in IT nor in datacenters, but the project intrigued me. And I would be allowed to do it remotely. No need to enter a loud server room. Win-win.
Need
Exercise an entire datacenter to prove a rare bug was no longer present for the new fleet of hard drives that we had installed. 1 week deadline.
Goal
Produce heavy long-term random load to exercise an entire data center.
How
Stand up 2000 VMs. Random data. Control and monitor load. Rapid iteration.
Result
Iterated 3 times in under a week and over a weekend (dedicated fun). Completed coding and testing with no supervision under budget and on time. Approx $3200 of $5000 budget. Success was confirmed. The bug was no longer present. I discovered other bugs and reported them.
