AWS Invests in Liquid Cooling for AI Servers
At AWS re:Invent in Las Vegas, Amazon Web Services (AWS) announced major updates to its data centers, focusing on efficiency, sustainability, and AI performance. The key highlight is the adoption of liquid cooling for its AI-focused Trainium2 chips and NVIDIA GB200 NVL72 systems, addressing the intense heat of next-gen workloads.
The new flexible cooling system integrates both air and liquid methods, ensuring cost-effective performance across diverse hardware.
AWS also simplified its electrical and mechanical systems, improving reliability to 99.9999% while cutting electrical disruptions by 89%. By reducing energy conversion steps, AWS boosts efficiency with a projected 6x increase in rack power density over two years.
To optimize operations, AWS uses AI-powered tools to configure rack positioning and streamline power usage. New control systems with real-time telemetry enhance diagnostics and troubleshooting.
AWS’s modular upgrades will retrofit existing facilities to meet growing AI demands while lowering its carbon footprint, maintaining its lead in cloud innovation.
