DeepGreen Hosting

OCF partners with hosting provider Deep Green who offer an innovative, sustainable approach to hosting.

Deep Green is a pioneer in building and operating modular, high-density data centers specifically designed for the demanding workloads of High-Performance Computing (HPC) and Artificial Intelligence (AI). Their core innovation lies in a unique, sustainable model that reuses the substantial heat generated by these high-power servers. By co-locating their data centers with "heat partners" such as swimming pools, public buildings, and industrial facilities, Deep Green provides a free and continuous source of heat. This not only significantly reduces their own operating costs but also creates a tangible, positive environmental impact by reducing carbon emissions and dependence on traditional heating methods.

The company's approach offers a compelling value proposition for partners in the HPC sector. By minimizing energy consumption and monetizing waste heat, Deep Green's model provides a pathway to carbon-neutral colocation hosting. This commitment to sustainability can help HPC clients meet their environmental, social, and governance (ESG) targets while benefiting from highly efficient infrastructure. The modular design of their data centers allows for rapid deployment and scalability, making it an agile solution for organizations with evolving computing needs.

From a technological and operational standpoint, Deep Green's data centers are built to handle the intense demands of modern computing. The high-density design is optimized for power-intensive racks, ensuring that partners can run their most critical and compute-heavy workloads without the typical power and cooling constraints. The waterless cooling system is another key feature, reducing operational complexity and eliminating the need for vast quantities of water, which is a major concern for many traditional data centers. This streamlined, efficient design supports a reliable and high-performance environment essential for HPC tasks.

With a growing network of live and planned sites across the UK and the US, Deep Green is actively expanding its footprint to serve a global clientele. By transforming what is traditionally seen as waste (heat) into a valuable resource, Deep Green is fundamentally changing the economics and environmental impact of data centers. Their model presents an opportunity for partners to collaborate on projects that are not only computationally powerful but also ecologically and economically beneficial, aligning the pursuit of performance with a commitment to a greener future.

ddn Storage

DDN EXAScaler is DDN’s enterprise implementation of the popular open-source parallel file system Lustre. It builds on the well proven parallel performance of Lustre and adds security and data management features comparable to leading proprietary parallel file systems.

We generally deliver this as an appliance on DDN hardware designed for high performance in both IOPS and throughput at scale.

It makes a great HPC scratch storage parallel file system combining low latency NVMe for metadata and a large quantity of hard disk drives for high parallel performance. Its use of high capacity QLC NVMe drives also makes it a cost-effective solution for all-flash deployments, well suited to AI or small-file bio-informatics workloads.
