NTT is launching two liquid cooling deployments in Japan to further the technology.
NTT Data is launching a demonstration data center to help verify the design and deployment of liquid systems, while NTT Communications is testing two-phase direct-to-chip cooling in an existing air-cooled facility.
NTT Data will provide liquid immersion cooling equipment, water-cooled racks, and servers, Hibiya Sogo Setsubi will build the verification facility, and Kuwana Kinzoku Kogyo will provide the chilled tower.
NTT Communications launched Green Nexcenter, a colocation service supporting direct-to-chip cooling, in October 2023. The company’s Yokohama 1 facility was the first site to offer the service.
Dell's new IR7000 supports up to 480kW per rack of computing power with Direct Liquid Cooling: flexible design with NVIDIA GB200 NVL4 or GB200 NVL72.
Dell has three example configurations of its new IR7000 server racks:
NVIDIA GB200 NVL4 with 144 B200 GPUs (30 trillion transistors)
NVIDIA GB200 NVL72 with 72 B200 GPUs
72 nodes of AMD EPYC 5th Gen CPU with up to 27,000 cores per rack
Dell's cutting-edge Integrated Rack Scalable Systems (IRSS) are designed for the most intensive AI workloads, with the company custom building the server racks to maximize space, enhance energy efficiency, and reduce costs.
Vertiv and Compass have partnered on a system that can switch from air to liquid cooling. The companies this week announced a partnership to develop a “first-of-its-kind” cooling solution with the ability to flex between air and liquid cooling to support high-density computing.
Vertiv is developing and manufacturing the technology, and the initial units will be deployed at a Compass facility in Q1 2025 as part of a planned multi-year, multi-billion dollar supply arrangement.
Vertiv CoolPhase Flex integrates liquid cooling capabilities with refrigerant-based air-cooling technologies and heat rejection in a single packaged system. It can be used initially as a direct expansion (DX) cooling system with integrated economization for air cooling, with liquid cooling capabilities engaged as more high-density computing is deployed.
At SC24 – this year’s edition of the US-based annual supercomputing conference – Nvidia made a slew of announcements, spanning hardware, AI for science, computer-aided engineering, and updated versions of the company’s CUDA-Q and cuPyNumeric solutions.
The GB200 NVL4 connects four Blackwell GPUs to two Grace CPUs.
Aimed at HPC and AI-hybrid workloads, the super chip features 1.3TB of coherent memory and, according to Nvidia, has 2.2X the simulation, 1.8X the training, and 1.8X the inference performance of its predecessor, the GH200 NVL4 Grace Hopper Superchip.
Despite the hype around Blackwell, Dion Harris, head of data center product marketing at Nvidia, said that Hopper will still continue to have “incredible value” amongst Nvidia customers.
The switch itself is made for HPE’s liquid-cooled supercomputing platforms. As such, and as something different from other 51.2T switches, it is completely liquid cooled designed to not use fans. That is a challenge since it has to cool not just the switch ASIC (Rosetta 2?) but also the optics.
The back of the switch interfaces with HPE’s HPC chassis. This is very similar to how blade chassis work if you are familiar with those switches.
On the front or rear, HPE has 24 optical cages. Pluggable optics at this speed generate enough heat that these need to be liquid-cooled in a switch like this as well.
It is great to see Slingshot move to the 51.2T and 400Gbps generation. At the same time, Broadcom’s 102.4T switches like the Delta DC-90640 are coming out in 2025.
Microsoft Azure has launched a cloud-controlled hybrid infrastructure platform called Azure Local for distributed locations.The technology giant has also revealed new DPU and HSM chips, plus other updates at its Microsoft Ignite 2024 event.
The HSM is a cloud security chip that gives users full administrative and cryptographic control, and means that Microsoft has no access or visibility of the keys stored within them.
The DPU is designed for "data-centric workloads with high efficiency and low power," and joins Azure's "processor trifecta" including CPUs and GPUs.
Microsoft has also launched Azure Local, a platform enabled by Azure Arc that brings Azure services to hybrid, multi-cloud, and Edge locations.
Microsoft and Atom Computing are planning to ship a commercial quantum machine that can outperform classical computing by the end of 2025.
The machine is being co-designed by Microsoft and Atom and, according to Microsoft, will be the world's largest commercial offering and will use entangled logical qubits that can detect and correct.
The Liquid Cooling Coalition recently presented a new ISO 31000 series risk assessment model assessing the top 200 risks in liquid cooling of electronics in data centers for peer review and feedback.
CoolIT Systems this week introduced the CHx1000, a new liquid-to-liquid coolant distribution unit (CDU) claimed as the world’s highest-density offering.
The company said the new cooling unit is purpose-built to cool the Nvidia Blackwell GPUs, delivering 1000kW cooling capacity with a flow rate of up to 1.5 liters per minute per kilowatt (LPM/kW) at a 3°C (37.4°F) approach temperature.

Sabey has partnered with liquid cooling hardware provider Seguente to offer high-density colocation across its portfolio.
The system uses a passive two-phase liquid cooling method with ultra-low global warming potential dielectric fluids, is waterless and pumpless, and can reportedly offer densities up to 250kW.
Meanwhile, Brazilian operator Elea has announced it has ordered hundreds of CDUs from Vertiv to support liquid cooling for AI applications at its São Paulo sites.
Eaton has launched a new air-cooled rack for Edge environments.
The company has launched a 5.5kW model of its SmartRack family of self-contained cooling rack enclosures.
Featuring a pre-installed, 12U cooling unit mounted at the bottom of a 42U heavy-duty custom rack, the SmartRack 5.5 kW can be deployed out of the box with an HVAC professional. It offers 27U of rack space for IT equipment.
Johnson Controls recently launched a new air conditioning unit.
Featuring a vertical downflow and draw-through layout, the York Mission Critical Vertical Computer Room Air Handler (MCV CRAH) can offer cooling in above-floor or under-floor data center applications. It is available in multiple capacities from 105kW to 550kW.
Accelsius, which provides two-phase, direct-to-chip liquid cooling, has raised $24 million as part of a Series A funding round.
The company this week also announced a partnership with iM Data Centers. IM will deploy Accelsius' NeuCool liquid cooling tech in its Miami data center, due to open in Q1 2025.
The 100,000 sq ft facility will initially offer 10MW, eventually scaling to 40MW.
Amazon plans to invest $4 billion in Anthropic.The deal follows a previous $4bn investment in the generative artificial intelligence startup.
Anthropic said in 2023 that it would collaborate in the development of future Trainium and Inferentia chips.
Earlier this month, Anthropic's Amodei said that $100 billion data centers were on the horizon to train the next generation of AI.
Nvidia's data center revenue for the latest quarter was $30.8 billion, up 17 percent from Q2 and up 112 percent from a year ago.
The world's most valuable company posted total revenues of $35.1bn, up 94 percent year-over-year.
For its data center revenue, $3.1 billion was spent on networking components.
The company forecasts total fiscal fourth-quarter sales of about $37.5bn, up 70 percent. That was above average analyst projections of $37.1bn, compiled by Bloomberg, but below some projections that were as high as $41bn.
Colovore is to expand its footprint of liquid-cooled colocation data centers beyond Silicon Valley and into Reno and Chicago.
On its website, Colovore said RNO01, in Reno, Nevada, is pre-leasing now for a 2026 launch date.
Colovore has reached out to say Reno is targeted as Q4 2025 and Chicago for Q4 2026, and confirmed Chicago will also be 20MW.
The company announced plans to build a second, 9MW facility known as SJC02, on a neighboring plot in November 2022.
Cerebras, Lambda Cloud, and Cirrascale, amongst others, are known customers of Colovore.
