Vertiv Holdings (NYSE:VRT) had dropped 8% by late Thursday morning trading after Amazon Web Services (NASDAQ:AMZN) provided details of its in-house cooling system for its data centers powered by Nvidia (NASDAQ:NVDA) GPUs.
David Brown, AWS’ vice president of compute and machine learning services, revealed his company’s In-Row Heat Exchanger cooling system in a blog and video post.
Vertiv also provides cooling technology for data centers, with one of its latest offerings being the CoolPhase Flex.
AWS’ new P6e-GB200 UltraServers, which are powered by Nvidia Grace Blackwell superchips, are specifically designed to handle the most sophisticated artificial intelligence models, Brown said.
“Whereas P6-B200 instances use our proven air-cooling infrastructure, P6e-GB200 UltraServers use liquid cooling, which enables higher compute density in large NVLink domain architectures, delivering higher system performance,” Brown said. “P6e-GB200 are liquid cooled with novel mechanical cooling solutions providing configurable liquid-to-chip cooling in both new and existing data centers, so we can support both liquid-cooled accelerators and air-cooled network and storage infrastructure in the same facility. With this flexible cooling design, we can deliver maximum performance and efficiency at the lowest cost.”
AWS announced the general availability of its P6e-GB200 UltraServers on Wednesday.
