Bridging the IT-Facility Divide: Navigating the Management Challenges of Liquid Cooling in Data Centers | Part 1

The IT-Facility Divide

In the current data center environment, there is a distinct demarcation between information technology (IT) and facility management. IT is primarily concerned with hardware, software, and networking components, while facility management focuses on physical infrastructure, such as power distribution and environmental controls. However, the advent of liquid cooling technology challenges this divide. In this first article of the series, we will trace the historical roots of the IT-Facility divide and examine how liquid cooling impacts this traditional structure. In subsequent articles, we will explore the operational models, the specific challenges faced by co-location data centers, and ultimately, the opportunities that arise when we bridge the IT-Facility divide.

The Historical Perspective

The delineation between IT and facility management in data centers emerged organically out of necessity, shaped by the evolution of technology and the demands of operational efficiency. In the early days of computing, mainframe machines were enormous, demanding sophisticated cooling and power supply systems. As the size of computers shrank dramatically with the advent of microprocessors and server technology, so too did the physical requirements of data centers.

This allowed for the development of a distinct realm of IT management focused primarily on the digital components of the data centers - the servers, the software, the data processing, and the network infrastructure. Meanwhile, facility management evolved to focus on the physical infrastructure that houses, powers, cools, and secures these IT elements. The specific skill sets, protocols, and priorities in each area solidified the divide, leading to the distinct IT and facility departments that we see in modern data centers today.

This historical evolution has established an effective system of specialization, allowing each group to develop expertise in their respective domains.

The relevance of the IT-Facility Divide in the industry

The historical separation between IT and facility management has not only proven to be efficient but is also critical to most data center environments. The separation has allowed for an environment of specialization, where IT professionals can focus on managing and optimizing the digital infrastructure, while facility management can ensure the physical environment's safety, efficiency, and resilience.

In the context of colocation facilities, this divide is even more pronounced. Colocation providers essentially offer the facility aspect as a service, taking responsibility for power, cooling, physical security, and other infrastructural concerns. In turn, their customers, typically businesses with significant IT needs, can concentrate solely on managing their digital assets, from servers to software to data.

This division of labor makes sense from both a logistical and security standpoint. It minimizes the risk of unauthorized access to the digital infrastructure, enhances the efficiency of operations, and allows for a higher degree of specialization within each domain. However, the advent of liquid cooling technologies, which blur the line between IT and facility management, is challenging this longstanding divide.

These technologies require a more integrated approach to data center management that traditional structures may not be adequately equipped to handle. It's a complex conundrum, a catch-22 situation that the industry must address as we navigate towards a future of sustainable and efficient data center cooling solutions.

A Challenge to the Status Quo

Liquid cooling presents a radical shift from traditional air cooling methods and is emerging as a critical element for the evolution of digital infrastructures. The technology operates on the principle of using liquids, which have high heat capacities, to absorb, transport, and dissipate the heat generated by IT equipment more efficiently than air.

However, the implementation of liquid cooling blurs the well-established IT-facility divide. Unlike air, which surrounds us in an abundant supply and can be managed with relative simplicity, liquids used for cooling demand careful handling and pose certain risks. These cooling fluids can penetrate the IT equipment's chassis and directly interact with the components, necessitating a more nuanced and integrated approach to management.

To better understand this, it's crucial to distinguish between the three main types of liquid cooling: Indirect, Direct, and Total liquid cooling. Indirect liquid cooling, exemplified by Door Heat Exchangers (Door HX), presents the least disruptive change. Here, the liquid coolant does not directly contact the IT equipment and the established IT-facility management responsibilities can still apply.

However, direct liquid cooling, like cold plates, brings the liquid coolant into the IT chassis. Total liquid cooling, such as immersion cooling, represents the most extreme form of this technology. It involves immersing the entire IT equipment in a bath of dielectric liquid coolant. With direct and total liquid cooling, the traditional lines between IT and facilities begin to blur, as the cooling medium now has a more intimate relationship with the IT hardware.

These cooling methodologies bring forth unique challenges and complex questions about managing such technologies, calling into question the existing division between IT and facility management, and raising new security and operational concerns. The industry must now navigate this shift, re-evaluating and redefining the roles of the IT and facility management teams in the era of liquid cooling. In our next article, we will delve deeper into how this transition might redefine roles and foster new collaborations.

Question: As we integrate liquid cooling into data centers, how might the roles of IT and facility management change? Could we see a new hybrid role emerge, or will teams adapt while keeping their specializations separate?
