Virtual Machines and Containers - Better Together

As artificial intelligence (AI) reshapes the data center landscape, power resiliency is being tested like never before. With enormous new facilities coming online and operators exploring alternatives to diesel, the backup power market is at an inflection point. In this episode of the Data Center Frontier Show, we sit down with Ricardo Navarro, Vice President of Global Solutions at Generac Power Systems, to discuss how the company is positioning itself as a major player in the data center ecosystem. Diesel Still Reigns — For Now Navarro begins by addressing the foundational question: why diesel remains the primary backup power choice for hyperscale and AI workloads. The answer, he explains, comes down to density, responsiveness, and reliability. Diesel engines respond instantly to the fluctuating loads that are common in AI training clusters, and fuel can be stored directly on-site. While natural gas is gaining traction as a bridging and utility-support solution, true redundancy requires dual pipelines — a level of infrastructure not yet common in data center deployments. That said, Navarro is clear that the story doesn’t end with diesel. He sees a future where natural gas, paired with batteries, becomes a cost-effective and environmentally attractive option. Hybrid systems, combined with demand response and grid participation programs, could give operators new tools for balancing reliability and sustainability. “Natural gas might not be the right solution right now, but definitely it will be in the future,” Navarro notes. Scaling Fast to Meet Hyperscaler Demands The conversation also explores how hyperscalers are shaping requirements. With campuses needing hundreds of generators, customers are asking not just about product performance, but about scale, lead times, and support. Generac is addressing that demand by delivering open sets in as little as 30 to 35 weeks — about a third of the wait time from traditional OEMs. That speed-to-deployment advantage has driven significant new interest in Generac across the hyperscale sector. From Generators to Energy Technology Equally important is Generac’s shift toward digital tools and predictive services. Over the past decade, the company has invested in acquisitions such as Deep Sea Electronics, Blue Pillar, and Off Grid Energy, expanding its expertise in controls, telemetry, and microgrid integration. Today, Generac is layering advanced sensors, machine learning, and AI-driven analytics onto its equipment fleet, enabling predictive failure detection, condition-based maintenance, and smarter load orchestration. This evolution, Navarro explains, represents Generac’s transformation “from being just a generator manufacturer to being an energy technology company.” What’s Next for Generac Looking ahead, the company is putting real capital behind its ambitions. Generac recently completed a $130 million facility in Beaver Dam, Wisconsin, designed to expand production capacity and meet surging demand from data center customers. With firm domestic and international orders already in place, Navarro says the company is determined “to be in the driver’s seat” as AI accelerates the need for scalable, resilient, and flexible backup power. For data center leaders, this episode provides a clear look into how backup power strategies are evolving — and how one of the industry’s largest players is preparing for the next wave of energy and infrastructure challenges.

Artificial intelligence is changing the data center industry faster than anyone anticipated. Every new wave of AI hardware pushes power, density, and cooling requirements to levels once thought impossible — and operators are scrambling to keep pace. In this episode of the Data Center Frontier Show, Schneider Electric’s Steven Carlini joins us to unpack what it really means to build infrastructure for the AI era. Carlini explains how the conversation around density has shifted in just a year: “Last year, everyone was talking about the one-megawatt rack. Now densities are approaching 1.5 megawatts. It’s moving that fast, and the infrastructure has to keep up.” These rapid leaps in scale aren’t just about racks and GPUs. They represent a fundamental change in how data centers are designed, cooled, and powered. The discussion dives into the new imperatives for AI-ready facilities: Power planning that anticipates explosive growth in compute demand. Liquid and hybrid cooling systems capable of handling extreme densities. Modularity and prefabrication to shorten build times and adapt to shifting hardware generations. Sustainability and responsible design that balance innovation with environmental impact. Carlini emphasizes that operators can’t treat these as optional upgrades. Flexibility, efficiency, and sustainability are now prerequisites for competitiveness in the AI era. Looking beyond hardware, Carlini highlights the diversity of AI workloads — from generative models to autonomous agents — that will drive future requirements. Each class of workload comes with different power and latency demands, and data center operators will need to build adaptable platforms to accommodate them. At the Data Center Frontier Trends Summit last week, Carlini expanded further on these themes, offering insights into how the industry can harness AI “for good” — designing infrastructure that supports innovation while aligning with global sustainability goals. His message was clear: the choices operators make now will shape not just business outcomes, but the broader environmental and social impact of the AI revolution. This episode offers listeners a rare inside look at the technical, operational, and strategic forces shaping tomorrow’s data centers. Whether it’s retrofitting legacy facilities, deploying modular edge sites, or planning new greenfield campuses, the challenge is the same: prepare for a future where compute density and power requirements continue to skyrocket. If you want to understand how the world’s digital infrastructure is evolving to meet the demands of AI, this conversation with Steven Carlini is essential listening.

In this episode of the Data Center Frontier Show, Editor-in-Chief Matt Vincent speaks with LiquidStack CEO Joe Capes about the company’s breakthrough GigaModular platform — the industry’s first scalable, modular Coolant Distribution Unit (CDU) purpose-built for direct-to-chip liquid cooling. With rack densities accelerating beyond 120 kW and headed toward 600 kW, LiquidStack is targeting the real-world requirements of AI data centers while streamlining complexity and future-proofing thermal design. “AI will keep pushing thermal output to new extremes,” Capes tells DCF. “Data centers need cooling systems that can be easily deployed, managed, and scaled to match heat rejection demands as they rise.” LiquidStack's new GigaModular CDU, unveiled at the 2025 Datacloud Global Congress in Cannes, delivers up to 10 MW of scalable cooling capacity. It's designed to support single-phase direct-to-chip liquid cooling — a shift from the company’s earlier two-phase immersion roots — via a skidded modular design with a pay-as-you-grow approach. The platform’s flexibility enables deployments at N, N+1, or N+2 resiliency. “We designed it to be the only CDU our customers will ever need,” Capes says. Tune in to listen to the whole discussion, which goes on to explore why edge infrastructure and EV adoption will drive the next wave of sector innovation. 

Every second an AI-enabled data center operates, it produces massive amounts of heat. Cooling needs are often thought of separately from heat, and for years, that is how systems were built. In most facilities, waste heat has to be managed, properly expelled, and is then forgotten. The heat may not be needed by the data center, but the question arises, ‘where else could this energy be put to use?’ What if energy use was viewed differently by data centers and the systems and institutions around them? Rather than focusing on a data center’s enormous power demands, let’s recognize data centers are part of a larger energy network, capable of giving back through the recovery and redistribution of thermal waste. The pursuit of heat reuse solutions drives technological advancements in data center cooling and energy management systems. Recovering waste heat isn’t just a matter of technology and hardware. Systems need to run smoothly, and uptime is critical. This can lead to the development of more efficient and sustainable technologies that benefit not only data centers but the communities they operate within, creating a symbiotic relationship. Join Trane® expert Esti Tierney as she explores critical considerations for enabling heat reuse as part of the circular economy. Esti will discuss high computing’s growing impact on heat production, the importance of a holistic view of thermal management, and why the need to collaborate and plan a heat redistribution strategy early with community stakeholders matters.   Heat reuse in data centers is a crucial aspect of modern energy management and sustainability practices, offering benefits that extend beyond the immediate operational efficiencies. Designing for optimized energy efficiency and recovering waste heat isn’t just about saving money. The ability to reduce energy demand on the grid will be critical for all today and into the future. As server densities increase and next-generation chips push power demands ever higher, waste heat is no longer a byproduct to manage — it's power waiting to be harnessed.
