Before deploying a new server, even a shiny new example from a tier 1 manufacturer, testing is still required. It’s far better to shakedown a server before deployment, than have your users do the testing for you!

While there are many tools available, I find Prime95 particularly useful. Not only does it do a thorough job of stress testing the processor, you’ll need however to run a separate instance for each core, but it has the handy side effect of giving other hardware areas a workout too.
