Welcome to Keep Your Cool—a series tackling simple cooling optimization strategies for busy data center operators.

Asking "What if?" isn't just a thought experiment; it's the cornerstone of resiliency planning in data centers. By questioning the robustness of your infrastructure, you initiate a critical evaluation of how well your cooling systems can withstand unexpected failures. We recently worked with a client who wanted to understand their data center's vulnerability to cooling failures without risking operational downtime. They were particularly concerned about how quickly they needed to react if a unit failed and the level of existing redundancy. During our planning call, they asked questions like:

• “How vulnerable am I if any one ofthe cooling units now operating were to fail?”

• “How much time do I have to respond to a failure before it becomes critical?”

• “What level of redundancy, if any, exists in the current design?”

Basically, our client wanted to know how vulnerable or likely are they to have cooling failures? Given their data center was the heart of their business, they can not afford to go down. Does this sound familiar?

To address these concerns, we conducted a series of controlled "What If" tests using predictive analysis. This approach allowed us to simulate failures and measure response times without reaching critical failure points, providing a safe yet effective stress test of the infrastructure. Here’s how it worked:

1. Developing a Solid Plan: We crafted a detailed plan that outlined which cooling units would be temporarily disabled to simulate failure scenarios.

2. Conducting Simulations: With precise real-time monitoring, we determined how long the data center could sustain operations under different failure conditions. This was achieved without actual disruptions, thanks to predictive analytics.

3. Communication and Training: Ensuring all stakeholders were informed and trained on the emergency procedures was crucial. This preparedness meant that, regardless of when a failure occurred, the team was ready to implement the mitigation strategies effectively.

The result was a comprehensive understanding of the data center's weaknesses and strengths in cooling infrastructure. This not only reassured the client of their system's capacity but also highlighted necessary enhancements to improve resilience.

While we strongly recommend working with professionals — like Purkay Labs. If you are asking your “What if” questions start by asking:

• What infrastructure components will be shut down to simulate a “failure” scenario?

• What you will observe in real time, 

• What limits of temperature rise for an abort test state, 

• What actions to be taken to restore the site to baseline readings.

Communicating with every stakeholder — from facilities to the IT to the budget provider— is going to be key.

Conclusion

Resiliency testing is more than a precaution—it's an integral part of operational integrity in data centers. By preparing for the worst, you ensure that your facility can handle any scenario, maintaining uptime and operational efficiency.
