Before we start, let us be clear about one thing: environmental monitoring and measurement systems are critical components in managing your data center. This is not a ‘one versus the other’ paper.
The value of monitoring systems is without question because they visualize what is happening in your data center right now, and they are the only reliable way for you to be alerted to critical problems caused by failure or human error. Despite this,
monitoring has some very serious blind spots.
Here are three compelling reasons why relying on monitoring alone will leave you vulnerable… and three reasons why a dedicated data center computational fluid dynamics (CFD) tool will overcome these limitations. In short, here are the reasons
why you should have both monitoring and Engineering Simulation.
1) YOU CAN’T MONITOR EVERYWHERE
Tech Takeaway: “…air temperature in a data center can vary by as much as 1 degree C per centimeter. If your three ASHRAE recommended sensors are several feet apart, that’s an awful lot of temperature variation that you’re not actually monitoring.”
2) YOU CAN’T MONITOR RESILIENCE
Tech Takeaway: “There really are only two reliable ways of measuring your resilience. Once comes at great risk, the other at zero risk; either you fail something for real, or you model that same failure in a safe simulation environment using CFD.”
3) YOU CAN’T MONITOR THE FUTURE
Tech Takeaway: “The answers to ‘What if…’ questions lie with the behavior of your cooling airflow, and we can tell you that it’s a fickle beast. No amount of historic data will let you tame it and projecting past performance onto future changes provides only the illusion of control.”
