Nvidia's Rubin Ultra NVL576 rack expected to be 600kW, coming second half of 2027

• Nvidia plans to launch the Rubin Ultra NVL576 rack in the second half of 2027, following next year's Rubin.

• The liquid cooled 'Kyber Rack' will consume some 600kW, Nvidia CEO Jensen Huang said at the company's GTC event.

• The Vera Arm CPU has 88 custom Arm cores, 176 threads, and 1.8TBps NVLink C2C. The Rubin Ultra includes fore reticle-sized GPUs, with 100 petaflops of FP4, and 1TB of HBM4e.

• The Rubin Ultra NVL576 offers 15 exaflops of FP4 inference and five exaflops of FP8 training, with the company claiming a 14x improvement over the GB300 NVL72.

• The rack has 4.6PBps of HBM4e, and 365TB of fast memory. It also has 1.5 PBps NVLink7, and 115TBps CX9.

• The following year will see the launch of the Feynman series of GPUs, named after Richard Feynman.

Nvidia announces latest DGX SuperPOD with Blackwell Ultra GPUs

• At its GTC event in San Jose, Nvidia debuted its latest SuperPOD system, itself a collection DGX systems.

• The Nvidia Blackwell Ultra DGX SuperPOD features the latest Blackwell Ultra GPUs, and comes in two flavors - DGX GB300 and B300.

• The DGX B300 can still be air-cooled and relies on the B300 NVL16 architecture. The GB300, meanwhile, combines the 72 Blackwell Ultra GPUs with 36 Grace CPUs and requires liquid cooling.

• Each DGX GB300 system also features 72 Nvidia ConnectX-8 SuperNICs, delivering networking speeds of up to 800Gb/s, double the performance of the previous generation. Eighteen Nvidia BlueField-3 DPUs combine with Nvidia Quantum-X800 InniBand or Nvidia Spectrum-X Ethernet.

• The Nvidia DGX SuperPOD with DGX GB300 or DGX B300 systems are expected to be available from partners later this year.

CoolIT releases new 1.5MW CDU

• Liquid cooling provider CoolIT Systems has launched a new high-capacity liquid-to-liquid cooling distribution unit (CDU).

• The company this week introduced the CHx1500, which it describes as the world’s highest-performing, most compact row-based CDU.

• The CHx1500 delivers 1500kW cooling capacity with a flow rate of up to 1.2 liters per minute per kilowatt (LPM/kW) at 5°C (41°F) approach temperature difference (ATD). It requires just over 12kW of power.

• The liquid-to-liquid CDU is reportedly able to cool up to nine Nvidia GB200 NVL72 racks or up to 63 “enterprise” racks.

• The rack-sized unit is front and back serviceable with hot-swappable critical components. Control of the unit is available through a 10” touchscreen or remotely through Redfish, SNMP, TCP/IP, Modbus, and several other protocols.

ExxonMobil announces Discovery 6 supercomputer to power oil and gas deposit mapping technology

• Oil and gas giant ExxonMobil has unveiled its Discovery 6 supercomputer, set to be installed in the first half of 2025.

• The system was developed through a partnership between HPE, Nvidia, and ExxonMobil, with the three companies saying Discovery 6 represents a “significant advancement” in supercomputing technology.

• The Discovery 6 will be combined with ExxonMobil’s elastic Full Wavefield Inversion (eFWI) technology to enable 4D seismic imaging of the Earth, allowing the company to locate oil and gas deposits for extraction “with unprecedented accuracy.

• Built by HPE, the Cray Supercomputing EX4000 machine consists of 4,032 Nvidia Grace Hopper Superchips, interconnected by HPE Slingshot technology and employing “energy-efficient 100 percent direct liquid cooling.”

• The system will have a 4x faster computational performance networking than its predecessor, Discovery 5, a 26.13 petaflops system that was installed in 2022 and ranked 46th on the most recent edition of the Top500 list of the world’s most powerful supercomputers.

Colovore launches liquid-cooled data center in San Jose, California

• Liquid-cooled data center firm Colovore has launched a new all-liquid facility in San Jose, California.

• Launched in 2013, Colovore carved out an early niche for liquid-cooled racks capable of up to 35kW. The company launched its original single-story, 24,000 sq ft (2,230 sqm) facility at 1101 Space Park Drive in Santa Clara, California in 2014, with the last 2MW expansion announced in February 2022.

• The company announced plans to build a second 9MW facility, known as SJC02, on a neighboring plot in November 2022. The facility, located at 3060 Raymond Street, can support densities up to 250kW per cabinet through a combination of rear door and direct-to-chip liquid cooling.

• Previously owned by Digital Realty Trust and Silicon Valley real estate development firm Pelio & Associates, investment firm King Street acquired the company last year.

• Colovore recently filed to develop a facility in the Hutto area of Austin, Texas, but is yet to officially announce the project.

Accelsius offers $100,000-per-rack insurance against cooling leak damage

• Liquid cooling firm Accelsius has launched a new cooling support program that provides insurance against leak damage.

• The two-phase, direct-to-chip liquid cooling provider has launched NeuGuard, a new support program. It offers a range of standard and optional support and white-glove professional services.

• Backed by CNA, one of the largest US warranty insurers, NeuGuard offers a custom multi-year warranty, flexible support, and up to $100,000 per rack coverage for internal damage from NeuCool leaks.

• Accelsius also now offers server-level warranties for leading OEMs globally. Following testing and validation by key OEM providers, SKU-level warranties are being introduced, offering client coverage alongside the NeuGuard offering.

• NeuCool’s system sees vaporators (also known as cold plates) mounted directly to targeted hot-spot chips. Dielectric refrigerant flows through the vaporators, where it nucleates into a vapor, which then travels to a CDU and condenses back into a liquid in a closed-loop system, then returning to the vaporator for additional cooling.

• Direct-to-chip systems usually rely on water, which has a high heat capacity, but Accelsius is using a dielectric coolant, and allowing it to boil in the circulating system, to remove more heat.

OData announces new data center in São Paulo, Brazil

• Latin American operator OData is developing a new data center in São Paulo, Brazil.

• The Aligned Data Centers company this week announced DC SP04, a new data center to be located in the city of Osasco, São Paulo.

• The company aims to invest more than $450 million on the 48MW facility. DC SP04 is scheduled to become operational in April 2025.

• The data center will be the first OData facility in Brazil to feature Aligned’s Delta Cube (Delta³) cooling system, with DC SP04 able to offer densities of up to 50kW per rack.

• OData is a subsidiary of Aligned Data Centers, which acquired the firm in May 2023. The company has operational facilities across the Latin American market, including Brazil, Chile, Colombia, and Mexico – with more in development.

• “Delta³ enables us to cool hyperscale IT environments efficiently, saving both energy and space. The system also seamlessly integrates with liquid cooling solutions, enabling OData to provide customers with high-density computing environments that can scale easily to accommodate AI, cloud, and high-performance computing deployments,” added Kelvin Tamura, design director at OData.

• Aligned launched a liquid cooling system in January 2024 called DeltaFlow~ that can be integrated with Delta³.

Up to 5GW data center with behind-the-meter hydrogen power promised for Laredo, Texas

• A data center campus of up to 5GW that utilizes its own behind-the-meter power supply is being planned for 50,000 acres of land in Texas.

• The data center will be built in phases, with the first 300MW and 1 million sq ft (92,903 sqm) of space set to launch in 2026. The company has not put a timescale on when it expects to reach the full 5GW build-out.

• It is claimed the facility will run on clean energy, eventually hydrogen power from another Energy Abundance Development Corporation project, Hydrogen City, which is being planned on an adjacent site. The first phase of this project is not set to come online until 2028.

• Energy Abundance recently rebranded from its old identity, Green Hydrogen International, and says its management team has extensive experience in large-scale global energy development and behind-the-meter project engineering, having developed, built, and financed over 3GW of power projects globally.

• "Many of these new data centers will require new power-dense racking and direct-to-chip liquid cooling designs, making off-grid, high-output new-build infrastructure like Data City vital for winning the AI race," said former McKinsey senior partner and Energy Abundance board member Andy Steinhubl.
