Submer and Aginode to jointly develop AI and DC infrastructure across MEA. As w.media's Global Editor-in-Chief, Grey covers the cloud and data center industry and connectivity ecosystem across APAC and EMEA. In a career spanning over two decades, Grey has dabbled in television, print and online journalism, covering a variety of beats including human rights, health, environment, politics, business and economy. October 28, 2026 at 7:23 PM GMT+8 Submer, a full-stack AI and HPC data center infrastructure provider, has signed a collaboration agreement with Aginode, a global provider of physical connectivity and power distribution for data centers, to jointly develop and deliver integrated AI and data center infrastructure across the Middle East, Africa, and Turkey. Under the agreement, both companies will work with customers from the first planning discussions to ensure that the facility's thermal, power, and connectivity are designed as one architecture. It aims to help customers by reducing the number of handovers between specialists during design, and providing a clearer view of how the facility will perform once it is built and running. Khalid Aljamed, General Manager, Middle East and Africa, Submer, said, "AI infrastructure in this region is being planned at a scale where the decisions made early in a project shape everything that follows. With Aginode, we can address thermal, power and connectivity together from the very first stage and give customers a more dependable path from design to delivery. We are pleased to formalize this collaboration and look forward to building on it with Yousef and his team." Yousef Arafat, General Manager, Aginode, added, "Submer's advisory, design and thermal expertise complements our connectivity and power distribution portfolio very well. Our teams are already working side by side with customers in the region, and this agreement gives us a firm foundation to expand that work across the Middle East, Africa and Turkey." The companies say that the move comes in response to the growing demand for AI capacity across the region, supported by national digital programs, sovereign AI initiatives and growing enterprise investment. As compute density increases, thermal, power and connectivity become closely linked, and decisions taken separately at the design stage can add cost and delay later in a project. Beyond individual projects, Submer and Aginode will collaborate on solution development, go-to-market activity and market intelligence. The two companies are already engaged with customers in the region, including in Egypt, and will target opportunities in AI factories, high-performance computing, hyperscale and colocation facilities, telecom networks and sovereign infrastructure programs.

Submer and Aginode partner to deploy integrated AI and data center infrastructure across MEA.

Submer and Aginode partner to deploy integrated AI and data center infrastructure across MEA. W.Media Published Oct 28, 2026 Full-stack AI and high-performance computing infrastructure provider Submer has entered into a collaboration agreement with connectivity and power specialist Aginode to co-develop integrated data centers across the Middle East, Africa, and Turkey. The partnership unites thermal design, power distribution, and physical connectivity into a single architecture from the earliest planning stages to reduce engineering handovers and improve post-construction operational reliability. The two companies are already actively engaging clients in markets such as Egypt, targeting AI factories, hyperscale facilities, telecom networks, and sovereign computing programs. Submer, a full-stack artificial intelligence and high-performance computing data center infrastructure provider, has signed a collaboration agreement with Aginode to jointly develop and deliver integrated data center systems across the Middle East, Africa, and Turkey, according to industry publication W.Media. The strategic alliance combines Submer's thermal management and specialized computing advisory with Aginode's portfolio in physical connectivity and data center power distribution. Under the terms of the agreement, the two infrastructure specialists will coordinate with enterprise and public-sector clients from the earliest planning discussions. The primary objective is to align thermal design, electrical power distribution, and physical cabling into a single unified architecture. Project leaders state that this consolidated workflow aims to assist data center operators by substantially reducing the number of handovers between disparate engineering specialists during the design phase, while providing a clearer view of operational performance once facilities are built and running. Leadership from both organizations underscored the operational necessity of early-stage integration. Khalid Aljamed, General Manager for Middle East and Africa at Submer, noted that artificial intelligence infrastructure in the region is expanding at a scale where early design decisions shape all subsequent project outcomes. Unifying thermal, power, and connectivity systems from the initial planning stage offers project sponsors a more dependable pathway from engineering to delivery. Yousef Arafat, General Manager at Aginode, highlighted that Submer's advisory, design, and thermal expertise directly complements Aginode's physical network and electrical portfolio, noting that joint teams are already active with clients on the ground. Background: Over recent years, digital transformation across the Middle East, Africa, and Turkey has shifted toward high-density workloads, driven by national digitalization roadmaps, telecommunications modernization, and government-backed sovereign AI strategies. Historically, data center development in emerging markets relied on fragmented multi-vendor procurement models where cooling systems, mechanical plant equipment, power distribution units, and optical networking were planned and sourced in silos. As compute density increases, this fragmented approach frequently risks mismatched specifications, project delivery delays, and capital expenditure overruns. Background: The rapid adoption of accelerated computing clusters powered by high-performance GPUs has dramatically heightened power draw and heat rejection requirements per rack. In regions characterized by extreme ambient temperatures or constrained water resources, conventional data center cooling and standard power grids encounter severe operational bottlenecks. As regional governments seek to build localized sovereign infrastructure to retain strategic data within national borders, demand has accelerated for turnkey solutions that resolve thermal and electrical interdependencies prior to physical construction. Industry analysts observe that while integrated infrastructure frameworks mitigate technical misalignment, executing joint multi-vendor designs requires close alignment between distinct engineering cultures and supply chains. Supporters emphasize that unified architectures drastically reduce integration friction for facility builders, lowering operational risk in high-density deployments. Conversely, independent observers note that joint vendor solutions must remain sufficiently adaptable to integrate with existing legacy systems and custom equipment preferences favored by international hyperscalers. Looking ahead, Submer and Aginode intend to move beyond individual site engagements by collaborating on broader solution development, joint go-to-market strategies, and regional market intelligence. The two companies are already actively working with customers in the region, including deployments in Egypt, and have outlined immediate plans to pursue major contract opportunities across AI factories, high-performance computing centers, hyperscale and colocation campuses, telecommunication carrier networks, and sovereign infrastructure initiatives. Why it matters The partnership directly lowers the engineering and deployment barriers for emerging markets seeking to establish local AI infrastructure. By eliminating fragmented contracting across cooling, power, and physical cabling, the unified model helps developing nations and regional operators build high-density compute facilities more cost-effectively and with fewer construction delays. This approach enables local telecommunications providers and smaller enterprises to host advanced AI workloads domestically, reducing reliance on distant cloud regions and strengthening sovereign data autonomy.

Submer Group launches Corenix for modular AI data centres.

Submer Group launches Corenix for modular AI data centres. Submer Group has launched Corenix, a modular data centre infrastructure business built on NVIDIA reference designs, appointing former Johnson Controls executive Martin Renkis as CEO. Submer Group has launched Corenix, a new company dedicated to delivering modular data centre platforms for neoclouds, hyperscalers and AI operators. The business builds custom-engineered modular platforms based on NVIDIA reference designs, factory-built and tested before being shipped and commissioned on site. Corenix designs, builds, integrates and factory tests complete IT, power, cooling and networking modules at production facilities before delivering them to project locations. Installation, connection to site infrastructure, site acceptance testing, commissioning and operational readiness then take place at the client site, with Corenix managing the full project scope across both stages. The launch responds to the inability of traditional, concrete-built data centres to keep pace with the power, networking, cooling and serviceability demands of accelerated computing, and with the need to support successive generations of high-density compute. Modular builds, tested in a factory before installation, allow capacity to be deployed as needed rather than overbuilt, which Submer says cuts construction times, waste and emissions while improving energy efficiency. Corenix draws on Submer Group's experience in high-density thermal engineering, global infrastructure deployment and operations. The company cites a campus with hundreds of megawatts of capacity delivered as a fully modular compute buildout in nine months from order to delivery, alongside more than a decade of liquid cooling engineering. Corenix sits alongside two other Submer Group companies: Rubix Data Centers, which develops and operates AI data centre campuses, and Radian Arc, which provides GPU-as-a-Service and AI-as-a-Service. Martin Renkis has been appointed CEO of Corenix. He joins from Johnson Controls, where he was executive director of Data Center Infrastructure Services, developing AI infrastructure offerings covering power, cooling, heat recovery, operations and financing. He previously founded and led Smartvue, an IoT hardware and software platform company acquired by Johnson Controls, and Trainersoft, an enterprise e-learning software company acquired by OutStart, now IBM. Corenix is headquartered in Houston, Texas. Submer Group, founded in Barcelona in 2015, says it has deployed more than 500 MW of liquid-cooled infrastructure and holds more than 8 GW of powered land across the Americas, EMEA and APAC, operating globally with hubs in Houston and Taipei.
