Can Modern Data Centers Keep up With the Exponential Growth of AI?

Artificial intelligence’s exponential development has stirred controversy and concern amongst information heart professionals. How will amenities accommodate the fast-approaching high-density kilowatt necessities AI requires? As typical options develop into much less possible, they need to discover a viable – and inexpensive – various. 

Data Centers Are Facing the Consequences of AI Demand 

AI’s adoption fee is steadily climbing throughout quite a few industries. It elevated to about 72% in 2024, up from 55% the earlier yr. Most metrics recommend widespread implementation is not a fleeting development, indicating fashionable information facilities will quickly must retrofit to maintain up with its exponential development. 

The current surge in AI demand has long-term implications for the longevity of information heart info expertise (IT) infrastructure. Since a typical facility can final 15-20 years, relying on its design and modularization, many operators are ill-prepared for the sudden, drastic change they now face. 

For many years, operators have up to date {hardware} in phases to reduce downtime, so many older information facilities are crowded with legacy expertise. Despite a number of large technological leaps, basic IT infrastructure has modified little or no. Realistically, whereas 10-15 kW per rack could also be sufficient for now, 100 kW per rack could quickly be the new commonplace.

What Challenges Are Data Centers Facing Because of AI? 

Current information heart capability requirements could develop into insufficient inside just a few years. The useful resource drain will likely be important whether or not operators increase gear to carry out AI capabilities or combine model-focused into current {hardware}. Already, these algorithms are driving the common rack density increased.

Currently, an ordinary facility’s typical energy density ranges from 4 kW to six kW per rack, with some extra resource-intensive conditions requiring roughly 15 kW. AI processing workloads function persistently from 20 kW to 40 kW per rack, that means the earlier higher restrict has develop into the naked minimal for algorithm functions.

Thanks to AI, information heart demand is ready to greater than double in the United States. One estimate states it will enhance to 35 gigawatts (GW) by 2030, up from 17 GW in 2022. Such a big enhance would require intensive reengineering and retrofitting, a dedication many operators could also be unprepared to make.

Many operators are involved about energy consumption as a result of they want up-to-date gear or an elevated server depend to coach an algorithm or run an AI software. To accommodate the elevated demand for computing sources, changing central processing unit (CPU) servers with high-density racks of graphics processing models (GPUs) is unavoidable. 

However, GPUs are very power intensive – they devour 10-15 instances extra energy per processing cycle than commonplace CPUs. Naturally, a facility’s current techniques possible will not be ready to deal with the inevitable scorching spots or uneven energy hundreds, impacting the energy and cooling mechanisms’ effectivity considerably.

While typical air cooling works nicely sufficient when racks devour 20 kW or much less, IT {hardware} will not be capable of preserve stability or effectivity when racks start exceeding 30 kW. Since some estimates recommend increased energy densities of 100 kW are potential – and will develop into extra possible as AI advances – this problem’s implications have gotten extra pronounced. 

Why Data Centers Must Revisit Their Infrastructure for AI

The strain on information facilities to reengineer their amenities is not a worry tactic. Increased {hardware} computing efficiency and processing workloads require increased rack densities, making gear weight an unexpected problem. If servers should relaxation on stable concrete slabs, merely retrofitting the area turns into difficult. 

While constructing up is far simpler than constructing out, it might not be an choice. Operators should contemplate options to optimize their infrastructure and save area if establishing a second flooring or housing AI-specific racks on an current higher stage is not possible. 

Although information facilities worldwide have steadily elevated their IT budgets for years, reviews declare AI will immediate a surge in spending. While operators’ spending elevated by roughly 4% from 2022 to 2023, estimates forecast AI demand will drive a ten% development fee in 2024. Smaller amenities could also be unprepared to decide to such a big soar. 

Revitalizing Existing Infrastructure Is the Only Solution

The necessity of revitalizing current infrastructure to fulfill AI calls for is not misplaced on operators. For many, modularization is the reply to the rising retrofitting urgency. A modular resolution like information heart cages can’t solely defend important techniques and servers, they will help air circulation to maintain techniques cool and supply an ease to scale as extra servers are wanted. 

Accommodating coaching or operating an AI software – whereas managing its accompanying huge information – requires an alternate cooling methodology. Augmented air may fit for high-density racks. However, open-tub immersion in dielectric fluid or direct-to-chip liquid cooling is good for delivering coolant on to scorching spots with out contributing to uneven energy hundreds. 

Operators ought to contemplate growing their cooling effectivity by elevating the aisle’s temperature by just a few levels. After all, most IT gear may tolerate a slight elevation from 68-72 F to 78-80 F so long as it stays constant. Minor enhancements matter as a result of they contribute to collective optimization. 

Alternative energy sources and methods are amongst the most essential infrastructure concerns. Optimizing distribution to reduce electrical energy losses and enhance power effectivity is important when AI requires wherever from 20 kW to 100 kW per rack. Eliminating redundancies and choosing high-efficiency options is important. 

Can Data Centers Adapt to AI or Will They Be Left Behind?

Data heart operators could also be keen to contemplate AI’s surging demand as an indication to overtake most of their current techniques as quickly as potential. Many will possible shift from typical infrastructure to fashionable options. However, tech giants operating hyperscale amenities can have a a lot simpler time modernizing than most. For others, retrofitting could take years, though the effort will likely be obligatory to take care of relevance in the business.
