Rittal Launches Modular Cooling System Capable of Exceeding 1 MW Output

### Rittal’s Bold Step into the Future of Data Center Cooling

In the ever-evolving world of data centers, where the demand for cooling solutions is as relentless as the heat generated by servers, Rittal is stepping up with a game-changing innovation. They’ve collaborated closely with hyperscalers and server Original Equipment Manufacturers (OEMs) to create a modular cooling distribution unit (CDU) that boasts a staggering cooling capacity of over 1 megawatt. This impressive piece of tech will be the star attraction at Rittal’s booth A24 during the 2024 OCP Global Summit, and it’s worth taking a closer look at what makes it tick.

At the heart of this CDU is a direct Liquid Cooling system that relies on water—a nod to the growing trend of using more efficient cooling methods in IT infrastructure. It’s not just about keeping servers cool; it’s about enabling the AI applications that are becoming central to so many businesses today. But how does Rittal ensure that this cutting-edge technology remains practical for everyday use?

Lars Platzhoff, Head of Rittal’s Business Unit Cooling Solutions, puts it succinctly: “To put the technology into practice, it is not enough to simply provide the cooling capacity and integrate the solution into the facility.” He emphasizes that while new technology is exciting, it must also be manageable for the data center teams who will operate it. This balance between innovation and usability is crucial, and ideally, it should be considered right from the design stage.

### A User-Centric Approach to Design

So, what does a user-friendly design look like in the context of data center cooling? Enter the Open Compute Project (OCP) and its modular design principles. Rittal has been a driving force behind the development of the Open Rack V3, which standardizes connections for power and cooling. This means that servers in the rack can easily connect to the CDU’s water circuit without a hitch.

Imagine a scenario where your data center team can slide in new cooling components like a new server—this is the kind of flexibility that Rittal is aiming for. The CDU is designed with modularity in mind, allowing for components such as controller units and coolant circulation units (CCUs) to be swapped out without shutting down operations. This “hot swap” capability is a game-changer, making maintenance less of a headache and more of a seamless process.

### The Future is Liquid

As we look ahead, it’s clear that the liquid-to-liquid cooling solution is poised to make waves, especially among hyperscalers—those giants of the tech world who run massive data centers. Platzhoff believes that the extensive testing and feedback from these players will likely set the standard for cooling solutions in the medium term. But what about the colocation sector, which often needs to move faster?

Colocators, who provide space and resources for various clients, are keen to offer robust solutions for AI and high-performance computing (HPC) without the long wait for standards to solidify. Rittal is addressing this need with alternative cooling options that don’t require a water connection. Their liquid-to-air systems cool processors with water but expel heat into the air through the rear door of the rack or a side cooler. While these solutions may not match the efficiency of liquid-to-liquid systems, they offer a quicker deployment for data centers lacking water infrastructure.

Think of it as creating mini “HPC islands” within traditional air-cooled data centers. This flexibility allows operators to test new technologies with less investment and effort, making it easier to adapt to the fast-paced demands of AI and HPC applications.

### Wrapping Up

As data centers continue to evolve, the need for innovative cooling solutions will only grow. Rittal’s modular CDU is a promising step in that direction, blending cutting-edge technology with practical usability. It’s a reminder that in the world of tech, progress isn’t just about flashy new products; it’s about making sure those products fit seamlessly into the lives of the people who use them. With the 2024 OCP Global Summit on the horizon, it will be fascinating to see how this technology is received and how it shapes the future of cooling in data centers. Are we ready to embrace this new era of efficiency? Only time will tell.

Technology Explained

HPC: HPC, or High Performance Computing, is a type of technology that allows computers to perform complex calculations and process large amounts of data at incredibly high speeds. This is achieved through the use of specialized hardware and software, such as supercomputers and parallel processing techniques. In the computer industry, HPC has a wide range of applications, from weather forecasting and scientific research to financial modeling and artificial intelligence. It enables researchers and businesses to tackle complex problems and analyze vast amounts of data in a fraction of the time it would take with traditional computing methods. HPC has revolutionized the way we approach data analysis and has opened up new possibilities for innovation and discovery in various fields.

Liquid Cooling: Liquid cooling is a technology used to cool down computer components, such as processors, graphics cards, and other components that generate a lot of heat. It works by circulating a liquid coolant, such as water or a special coolant, through a series of pipes and radiators. The liquid absorbs the heat from the components and then dissipates it into the air. This technology is becoming increasingly popular in the computer industry due to its ability to provide more efficient cooling than traditional air cooling methods. Liquid cooling can also be used to overclock components, allowing them to run at higher speeds than their rated speeds. This technology is becoming increasingly popular in the gaming industry, as it allows gamers to get the most out of their hardware.
