➀ Delta has showcased a next-generation switch, the DC-90640, designed for the 1.6TbE networking generation. The switch is capable of 102.4Tbps and is set to be released in 2025. It features a liquid-cooled design and supports 64 ports via 1.6T OSFP cages. The switch is powered by dual 4.5kW power supplies and is expected to support 30W modules. ➁ The switch is expected to use Broadcom's Tomahawk 6 switch chip, which is scheduled for 2025. It will also support PCIe Gen6 NICs for 800GbE, enabling 128x 800G connections per switch. ➂ The networking infrastructure is crucial for AI buildouts, as it requires many switches and high-bandwidth switches to reduce radix and minimize tail latencies.
