The Revolutionary Era of Submerged Data Centers

In today's digital age, our online lives are heavily reliant on data centers that process vast amounts of information every Second. As our dependence on cloud-based services continues to grow, the need for energy and time-efficient data centers becomes increasingly crucial. With this in mind, Microsoft has embarked on a groundbreaking experiment that may redefine the future of data centers, and for all the right reasons.

On July 9, 2020, Microsoft resurfaced its "Northern Isles," a 12.2-meter-long steel cylinder that had been submerged on the seabed for two years. Located 10 miles off the coast of Scotland in the Orkney Isles, this long-term experiment aimed to analyze the feasibility and advantages of underwater data centers. The environmentally green sources of energy, such as wind and solar, in the Orkney Isles made it an ideal location for this project.

The Challenges of Land-based Data Centers

Data centers located on land face a myriad of challenges that can impact their efficiency and reliability. Land-based facilities are exposed to environmental factors such as oxygen, humidity, and temperature fluctuations, which can lead to corrosion and increased cooling costs. Moreover, regular cleaning and maintenance activities can pose risks to the equipment's longevity.

Advantages of Submerged Data Centers

Submerging data centers in airtight, waterproof containers alleviates many of the challenges faced by land-based facilities. The constant cool temperatures of the seawater provide excellent thermoregulation, reducing the need for energy-intensive cooling systems. Approximately one-fifth of a data center's energy consumption is attributed to maintaining a cool temperature, but this is significantly reduced when surrounded by seawater.

Microsoft's Project Natick envisions offshore submerged data centers powered by wind farms, negating concerns about reliance on traditional energy sources. By dispersing multiple smaller data centers among populations, rather than relying on a single external warehouse, energy consumption can be minimized, providing stable access to customers while reducing environmental impact.

The Concept of Microsoft's Project Natick

Project Natick was conceived during Microsoft's ThinkWeek in 2014, an event where employees share advanced new ideas. The multinational effort to bring this concept to reality involved building a cylindrical pressure vessel in France, loading it with servers, and connecting it to underwater cables in the European Marine Energy Center in Scotland, before submerging it in June 2018. This underwater data center housed 864 servers with a total storage capacity of 27.6 petabytes.

The Success of Project Natick

After two years of being submerged, Project Natick's retrieval confirmed that submerged data centers are eight times more reliable than their land-based counterparts. Despite a few failed servers, which were taken offline, no maintenance was required during the testing stage. Microsoft engineers speculate that filling the container with dry nitrogen instead of oxygen contributed to its extraordinary success, as nitrogen is less corrosive.

Environmental Impact and Concerns

The environmental impact of data centers has long been a concern, accounting for nearly two percent of the planet's entire carbon footprint. However, the impact of submerged data centers on surrounding water temperature is negligible, given the ocean's inherent ability to dissipate heat. In fact, these structures can serve as attractants for fish and other marine life, creating new habitats and contributing positively to marine ecosystems.

Post-experiment Actions

Once the data center was resurfaced, efforts were immediately made to restore the seabed to its original state. Microsoft ensured that all components, including the steel pressure vessel, heat exchangers, and servers, were either recycled for materials or repurposed within the company's operations. By adopting responsible practices throughout the project's lifecycle, Microsoft demonstrates its commitment to minimizing environmental impact.

The Future of Submerged Data Centers

While sinking data centers on the seafloor may not replace land-based facilities entirely, it presents a viable alternative to meet the increasing demand for cloud-based services. The success of Project Natick opens doors for further research and development in the realm of submerged data centers. As technology advances, we can expect to witness more efficient, reliable, and environmentally friendly data center solutions.

In conclusion, Microsoft's Project Natick represents a revolutionary step towards redefining the future of data centers. This endeavor showcases the potential benefits of submerged data centers in terms of energy efficiency, reliability, and environmental impact. While the full extent of this technology's capabilities is yet to be explored, one thing is certain: the era of submerged data centers has arrived, bringing with it tremendous potential for a more sustainable digital future.
