Upscale AI, a Santa Clara networking startup backed by Nvidia, launched a platform on Thursday that lets data centres link AI chips made by different suppliers, Reuters reported.
The product, called Token Fabric, was revealed in a company announcement today. Upscale said it is built on open standards and works with graphics chips, custom AI chips, and network cards from any vendor.
Large AI systems distribute work across thousands of chips that must constantly exchange data. Networking gear links chips within a single server rack, known as scale-up. It also links racks across a building, known as scale-out. When data moves too slowly, costly chips sit idle.
Many of today’s biggest systems use one vendor’s own links, such as Nvidia’s NVLink. Upscale instead backs shared standards, including UALink and Ethernet for Scale-Up Networking (ESUN), so that chips from rival makers can sit on the same network.
Token Fabric combines SkyFabriX, Upscale’s own scale-up switch chip, with scale-out switches built on Nvidia’s Spectrum-X Ethernet chips.
Two software layers, SkyOS and SkyCMD, run and monitor the whole network. According to Reuters, the software can identify bottlenecks and flag hardware that may need replacement.
“The network is the backbone of the AI factory, keeping accelerators connected and productive as systems scale,” Gilad Shainer, Nvidia’s senior vice president of networking, said in the statement.
