- Liquid cooling is not non-compulsory anymore, it is the one method to survive AI’s thermal onslaught
- The bounce to 400VDC borrows closely from electrical car provide chains and design logic
- Google’s TPU supercomputers now run at gigawatt scale with 99.999% uptime
As demand for synthetic intelligence workloads intensifies, the bodily infrastructure of data centers is present process fast and radical transformation.
The likes of Google, Microsoft, and Meta at the moment are drawing on applied sciences initially developed for electrical automobiles (EVs), notably 400VDC methods, to deal with the twin challenges of high-density energy supply and thermal administration.
The rising imaginative and prescient is of information heart racks able to delivering as much as 1 megawatt of energy, paired with liquid cooling methods engineered to handle the ensuing warmth.
Borrowing EV know-how for knowledge heart evolution
The shift to 400VDC energy distribution marks a decisive break from legacy methods. Google beforehand championed the trade’s transfer from 12VDC to 48VDC, however the present transition to +/-400VDC is being enabled by EV provide chains and propelled by necessity.
The Mt. Diablo initiative, supported by Meta, Microsoft, and the Open Compute Venture (OCP), goals to standardize interfaces at this voltage degree.
Google says this structure is a practical transfer that frees up helpful rack area for compute sources by decoupling energy supply from IT racks by way of AC-to-DC sidecar items. It additionally improves effectivity by roughly 3%.
Cooling, nevertheless, has turn out to be an equally urgent subject. With next-generation chips consuming upwards of 1,000 watts every, conventional air cooling is quickly changing into out of date.
Liquid cooling has emerged as the one scalable answer for managing warmth in high-density compute environments.
Google has embraced this method with full-scale deployments; its liquid-cooled TPU pods now function at gigawatt scale and have delivered 99.999% uptime over the previous seven years.
These methods have changed massive heatsinks with compact chilly plates, successfully halving the bodily footprint of server {hardware} and quadrupling compute density in comparison with earlier generations.
But, regardless of these technical achievements, skepticism is warranted. The push towards 1MW racks relies on the idea of repeatedly rising demand, a pattern that won’t materialize as anticipated.
Whereas Google’s roadmap highlights AI’s rising energy wants – projecting greater than 500 kW per rack by 2030 – it stays unsure whether or not these projections will maintain throughout the broader market.
It’s additionally value noting that the combination of EV-related applied sciences into knowledge facilities brings not solely effectivity features but additionally new complexities, notably regarding security and serviceability at excessive voltages.
Nonetheless, the collaboration between hyperscalers and the open {hardware} group alerts a shared recognition that present paradigms are now not enough.
