OCP Global Summit: Nvidia, Arm, Kioxia and Cooler Master unveil AI data center hardware

At the Open Compute Project summit in San Jose, Nvidia contributed rack and compute tray designs for its Vera Rubin platform via MGX, using fully liquid-cooled, fanless and cable-free systems. Arm proposed a use-case methodology for measuring CPU performance in agentic AI, Kioxia launched LD4 SSDs up to 30.72TB, Cooler Master showed a 2,500 kW CDU, and Flex expanded its modular data center portfolio.

• Nvidia submits Vera Rubin rack and tray designs to OCP via MGX, fully liquid-cooled with no fans or cabling
• Arm: AGI CPU delivers up to 2.2x better reasoning performance per rack versus AMD Epyc Turin
• Kioxia LD4 SSDs use 8th-gen BiCS FLASH QLC NAND with 15.36TB and 30.72TB capacities
• Cooler Master's 2,500 kW CDU supports up to 990 gallons per minute, mass production in Q4 2026
