Sustainable Colocation Services – Midmarket
Portus Data Centers, headquartered in Luxembourg, was founded in 2023. The agile company operates one data center in Munich and two in Hamburg, Germany. At the Munich location, second data center is currently under construction and will be available later this year; a third is planned for Hamburg.
Strengths
Colocation services in highly secure data centers: Portus Data Centers offers high-quality colocation services in highly secure and fault-tolerant data centers. The offering includes the option to house hardware in racks, private cages or private suites for customers with high-security requirements. Colocation services, such as remote and smart hands, hardware handling, monitoring and backup solutions, are additional options that are difficult to implement in an in-house data center.
Focus on sustainability: Portus Data Centers follows a clearly defined ESG strategy. Sustainability is a key factor in investment and site selection decisions. All data centers are powered 100 percent by renewable energy. The average PUE is 1.37; the goal is to achieve a value of <1.3 by 2030.
AI infrastructure at the new Munich data center: Portus Data Centers has developed its own AI-native reference design for the new data center in Munich (MUC2), which is tailored to AI and HPC requirements. The infrastructure includes ultra-high-density racks and liquid cooling (D2C) for GPU and HPC clusters, AI inference and training, and HPC applications. The AI offering is particularly well-suited for regulated industries such as banking and manufacturing, public AI models and sovereign AI stacks, an advantage over hyperscalers.
Caution
Portus Data Centers offers a comprehensive colocation portfolio, state-of-the-art services and a compelling sustainability strategy. However, it still lacks waste heat projects, which are becoming increasingly important.
„Portus Data Centers emerged as a Rising Star with its secure, sustainable and future-proof data center infrastructure in Germany, focusing on energy efficiency, AI capabilities and digital sovereignty.“
