With their increasing importance for modern business operations, ensuring data centers remain functional during significant environmental or power-related events has become crucial. At PowerSecure, we’ve observed that while many professionals develop Business Continuity Plans (BCPs), key elements of energy resiliency and reliability are often overlooked. The good news is that with the right strategies in place, your data center can thrive even during unexpected events. Let’s explore the top best practices that can help you craft a comprehensive, resilient BCP.

A comprehensive approach to business continuity planning should work alongside a formal data center disaster recovery strategy. Every organization should maintain a documented disaster recovery plan that aligns with its overall business continuity management framework.

An effective continuity plan begins with a thorough risk assessment and a detailed business impact analysis. These steps help leadership understand vulnerabilities, define acceptable downtime, and protect essential workloads.

Understanding Data Center Threats and Vulnerabilities

A strong BCP addresses a variety of potential risks. From natural disasters to cyberattacks, each threat presents its unique challenge. With careful planning, however, your data center can not only endure but emerge stronger. In regions with harsh or unpredictable weather, fluctuating energy costs, or wildfires, the need for the ability to efficiently generate power onsite is increasingly important. While power resilience is often at the forefront, we’ll explore several other important factors that contribute to overall business continuity.

Power Disruption

Power disruptions remain one of the most common causes of data center downtime. Whether it’s due to inclement weather, rolling blackouts, or power grid instability, unexpected outages can be a significant threat to uninterrupted operations. Buildings Magazine discusses how extreme weather events are the most common culprit for data center downtime; a dangerous threat that has increased in likelihood and severity in recent years. However, with the right safeguards in place, such challenges can be mitigated.

Key Scenarios to Prepare For:

• Inclement Weather: As climate change leads to more frequent and severe weather patterns, data centers are more vulnerable to hurricanes, floods, and snowstorms. But by strengthening power resiliency, you can keep operations running even in the face of extreme conditions.
• Rolling Blackouts: In regions prone to heatwaves or cold snaps, local utilities may enact rolling blackouts to protect the grid. This is where robust backup power solutions come into play, ensuring your data center remains unaffected.
• Power Grid Instability: Aging infrastructure combined with increasing energy demands poses risks to power stability. Yet, with careful planning, your data center can maintain uptime regardless of external grid issues.

Bandwidth and Consistent Internet Connection

Reliable internet access is crucial for data center uptime. Any disruption in bandwidth or connectivity can slow down or halt critical operations. However, with redundancy measures, such as backup internet service providers (ISPs) or satellite solutions, your data center can continue functioning seamlessly, even during outages. A strong business continuity plan should include redundant internet feeds from different carriers, diverse physical circuits, and various technologies like fiber or Metro Ethernet. Monitoring the status and usage of all circuits is essential to prevent bottlenecks or downtime, especially during high usage or external threats like DDoS attacks. Ensuring both capacity and reliability, along with proactive monitoring, helps prevent service disruptions and maintains connectivity.

Cyberattacks

Cybersecurity has never been more critical. Cyberattacks targeting data centers or utility grids are becoming increasingly sophisticated, yet with strong security protocols and backup systems in place, the damage from an attack can be significantly minimized. “U.S. power grids are increasingly vulnerable to cyberattacks, with the number of susceptible points in electrical networks increasing by about 60 per day, the North American Electric Reliability Corporation (NERC) said in a webcast.” Safeguarding both power supply and internet connectivity is key to protecting operations.

Rising Utility Costs

Another growing concern is the rise in utility costs, especially during peak energy demand periods. Incorporating strategies that anticipate these cost fluctuations allows your business to remain financially stable, even during periods of high energy pricing.

Strong critical load continuity planning ensures that essential systems remain powered during disruptions. By prioritizing key resilient power infrastructure, organizations can support mission-critical facility continuity even during extended outages.

Clear recovery benchmarks are equally important. Defining a recovery time objective and recovery point objective allows organizations to restore systems efficiently while minimizing data loss and operational impact.

5 Best Practices for Your Data Center Business Continuity Plan

The following best practices will not only prepare your data center for challenges but also help you build resilience, optimize costs, and ensure that your business remains operational under any circumstances.

1. Seek Out Reliable, Off-grid Backup Power

Utility power disruptions don’t have to equate to downtime. By investing in off-grid microgrids, your data center can maintain a steady power supply, even in the most challenging scenarios. Off-grid systems offer independence from utility power and provide the flexibility to manage your energy needs.

Benefits of Off-grid Backup Power:

• Uninterrupted Operations: Off-grid microgrids ensure that your data center remains fully operational, even when the main power grid is compromised.
• Resilience in Natural Disasters: Whether facing hurricanes or earthquakes, having a reliable off-grid backup ensures continuous operations without relying on external sources.

2. Protect Your Equipment with Blip-less Transfer

Power transfer gaps can be detrimental to data center equipment. A blip-less transfer system eliminates these gaps, allowing for smooth transitions between power sources without disruption. This ensures that sensitive equipment remains protected from potential damage.

Why Blip-less Transfer is Essential:

• Seamless Power Transition: As soon as utility power is lost, your backup system kicks in without any interruption, ensuring your servers and other critical infrastructure continue to function.
• Automatic Activation: With autonomous local controls, backup systems can engage immediately, ensuring no time is lost during the switch.

3. Prioritize Energy Resource Flexibility

Diversity in energy sources is key to maintaining resilience. Relying on one type of energy, such as diesel, can leave your data center vulnerable to supply chain disruptions or price fluctuations. A diversified energy mix, including natural gas, solar, and clean diesel, provides additional security and environmental benefits.

Flexible Energy Solutions:

• Natural Gas and Clean Diesel: These fuel sources are reliable, efficient, and crucial for maintaining uninterrupted power during outages.
• Renewable Energy: Solar power integration offers a sustainable alternative that reduces reliance on traditional energy sources and enhances overall resilience.

4. Weatherproof Your Data Center Facilities

While no facility can be fully weatherproof, partnering with companies experienced in power resiliency during extreme weather is crucial. PowerSecure has a strong track record of providing energy resilience and reliability for data centers, even through severe storms. For example, during Hurricane Irma, PowerSecure’s solutions kept over 800 Florida facilities keep their lights on for extended periods.

Investing in data center power resilience strengthens overall uptime and reduces operational risk. Solutions such as grid-independent power systems and strategic on-site generation allow facilities to operate independently during utility disruptions.

An effective uptime strategy also includes structured outage preparedness procedures to ensure staff and systems can respond quickly to grid instability.

5. Rely on Redundancy Instead of Simplicity

• Although complexity in data center systems may introduce additional points of failure, it also increases overall resilience. Redundancy, whether in power systems, internet connections, or cooling mechanisms, ensures that if one system fails, another is ready to take over. In a PowerSecure blog post, we go into detail on this point, explaining how any risk in complexity is offset by the resiliency benefits. Complexity does create more points of failure, but it adds redundancy and flexibility. You must look at the whole picture and consider the number of points of failure, but also the number of points of resiliency.

The Value of Redundancy:

• Multiple Layers of Protection: By implementing redundant systems, you ensure that your data center is protected from single points of failure, enhancing overall stability.
• Balancing Complexity and Resilience: While more complex systems introduce risk, they also add much-needed flexibility, ensuring uninterrupted service even in challenging situations.
