Josh Claman, CEO of Accelsius – Interview Sequence


Josh Claman is the CEO of Accelsius, he’s an professional international government with over 30 years of expertise in knowledge heart know-how. He’s pushed progress and innovation at NCR, AT&T, and, as a Dell Government, he managed vital enterprise items throughout Europe and the Americas, together with as Common Supervisor of Dell UK. Publish-Dell, he has led ventures in 3D printing and digital well being, championing transformative tech. He holds levels with honors from the College of Illinois and superior enterprise {qualifications} from the College of South Carolina and Oxford College. 

Accelsius was fashioned in 2022 to develop and commercialize a cooling answer system primarily based on years of scientific thermal analysis carried out by Bell Labs. Based by Innventure — a know-how commercialization firm that makes a speciality of figuring out, funding, and scaling disruptive applied sciences — our specialists have created a brand new liquid cooling system that’s serviceable, scalable and resilient: NeuCool.

Are you able to inform us about the way you grew to become the CEO of Accelsius to commercialize its liquid cooling know-how?

Over the previous 18 months, the information heart trade acknowledged that conventional, brute drive air cooling methods had reached their limits for knowledge facilities as new rising AI, machine studying and different compute-intense purposes began flooding knowledge facilities from Hyperscalers to enterprise and COLO operations.  To maintain tempo, chip and server efficiency and ensuing wattages, and the related thermals,  had been rising at an unanticipated price. Innventure, which funds progressive and sustainable know-how corporations, recognized an IP from Nokia Bell Labs that delivered a two-phase, direct-to-chip answer that had the potential with additional superior engineering improvement and productization to revolutionize the trade.

Innventure purchased the IP and requested me to return on board to construct the corporate and commercialize the NeuCool know-how into an enterprise-class answer. Quickly after that, ChatGPT was launched only a few months later. This accelerated us into an amazing progress part with high-TDP, AI chips that demanded liquid cooling.

How does Accelsius’ two-phase, direct-to-chip liquid cooling system differ from conventional air cooling strategies?

Air cooling is a standard however remarkably energy-inefficient answer used to chill knowledge facilities, notably in dry, scorching climates. As chips turn into extra highly effective and compute calls for develop, air cooling turns into more and more unsustainable and in-efficient. Air is just not a great conductor of warmth in contrast with liquid, which has as much as 4,000 occasions larger quantity of warmth rejection in contrast with air.

With NeuCool, Accelsius direct-to-chip know-how, the A1 safety-rated liquid coolant is pumped to Vaporators (or engineered chilly plates) instead of the heatsinks on digital parts in an air-cooling configuration. Whereas a lot of the warmth (80%) is taken away by the NeuCool 2 part Vaporators on the chip-level (CPU, GPU) and through the whole cooling loop, followers are nonetheless wanted to assist take away warmth on the board stage, however at a really low quantity and velocity typically.

Direct to chip liquid cooling has an estimated 50% financial savings in vitality prices and CO2 emissions compared to conventional air cooling.

Are you able to clarify the environmental advantages of your cooling know-how, notably when it comes to CO2 emissions and water utilization? 

We use as much as half as a lot electrical energy as an air-cooled knowledge heart – which suggests we cut back CO2 emissions by the identical quantity. We additionally eat zero water in our system, resulting in larger environmental impacts.

How does Accelsius Ascent Mannequin assist knowledge heart operators transition from air to liquid cooling?

Many new knowledge heart and edge computing build-outs are being architected and constructed to facilitate liquid cooling from the beginning. For brownfield or present knowledge facilities, NeuCool is uniquely in a position to be simply retrofitted with the acquainted type issue of a direct-to-chip answer.

The Accelsius Ascent Mannequin is a collaborative program that allows, empowers and actively guides knowledge heart operators by way of a progressive transition to liquid cooling. This distinctive program ensures that clients systematically obtain most assist, worth and all key advantages of the NeuCool System.

We guarantee a easy transition into liquid cooling from air cooling probably reaching its limits. The method entails modifications or retrofits to the server, rack and even facility. Our Kickstart program, a part of the Ascent mannequin, gives clients keen to strive liquid cooling an opportunity to plan, check and acquire expertise in liquid cooling and forecast a hybrid IT setting for a easy transition away from air cooling.

What challenges did you face whereas commercializing your know-how, and the way did you overcome them?

The historic provide chain disaster impacted our sector notably onerous, and this was one thing I used to be keenly conscious of as I used to be working to scale Accelsius in 2022. We’ve prioritized a multi-layer AVL that may defend us sooner or later, and have additionally dedicated to having 85% of our prime  distributors be NAM primarily based to allow a extra accountable provide chain.

We even have a dynamic manufacturing and meeting mannequin which blends decrease quantity, early stage in-house manufacturing with an built-in tier 1 international manufacturing companion, which provides us extra management and suppleness.

How do you see the position of liquid cooling evolving as AI and machine studying applied sciences proceed to advance?

As AI and ML developments enhance, direct to chip liquid cooling will ultimately turn into the de-facto cooling know-how in knowledge facilities. Leaders at NVIDIA and Intel have already declared this in current bulletins,  supported by this weblog right here.

What recommendation would you give to different entrepreneurs seeking to sort out complicated technical challenges within the {hardware} know-how area?

Don’t get too far forward of your self and run out of runway: this is without doubt one of the fundamental causes onerous tech companies fail.

Whereas the phrase “Transfer sluggish, don’t break issues” works nicely for corporations that emphasize velocity and experimentation, the precise reverse is true for these pursuing operational innovation.

It is very important do not forget that simply because a know-how or new manner of doing enterprise is novel doesn’t imply it’s all the time applicable for the customer or the market. Operational innovation outcomes from a cautious strategy constructed with iterative steps quite than transformational ones.

Are you able to share any success tales or case research the place Accelsius’ know-how has made a major impression on knowledge heart operations?

One noteworthy companion is Texas Superior Computing Middle (TACC). We now assist Vista, which is a brand new modern, high-performance supercomputer, that manages TACC’s AI workloads. Vista makes use of NVIDIA GH100 Grace Hopper Superchips with TDPs as much as 1000 watts per socket.

As per confidentiality requirements, we plan to launch further buyer profiles quickly.

What do you assume are the most important misconceptions about liquid cooling know-how within the trade at the moment?

There are just a few misconceptions about liquid cooling within the trade that I’m completely satisfied to handle.

First, we now have seen some hesitation in combining liquids and servers inside knowledge heart racks. Our direct-to-chip structure is closely engineered to forestall leakage, subsiding this widespread concern. Within the uncommon occasion that there’s a leak, the dielectric fluid we use will not destroy or harm servers.

One other frequent false impression is that liquid cooling applied sciences are tough to implement into present brownfield knowledge facilities. If finished accurately, direct-to-chip cooling know-how ought to match into conventional racks  with out the necessity for particular mounting or tough retrofitting.

How does Accelsius plan to scale its operations to fulfill the rising demand for superior cooling options?

We have now a sturdy product portfolio, enabling modular constructing of liquid cooling options from one rack to many – with growing warmth elimination functionality as rack densities proceed to develop. We even have an expansive companion eco-system that allows us to assemble, deploy, combine and repair at quantity and throughout a large geographic protection space. Lastly, in 2024 we have launched our presence in Europe, and can proceed to increase our providers there.

Thanks for the nice interview, readers who want to study extra ought to go to Accelsius
