Panmesia expands into UALink and Ethernet

The expansion into accelerator-centric interconnects based on open standards such as UALink and Ethernet broadens Pennesia’s range of interconnect technologies for AI datacentres.

UALink is an open interconnect standard jointly driven by global big tech companies including AMD, AWS, Google, Microsoft and Meta, along with Panmnesia and many other member companies. It is designed to enable high-speed connectivity between AI accelerators regardless of manufacturer.

Ethernet-based interconnect technologies are also being proposed and developed. A notable example is ESUN (Ethernet for Scale-up Networking), led by the Open Compute Project (OCP), a leading open standards body for AI infrastructure. Panmnesia is also an active member of OCP.

Under this project Panmnesia will develop controllers and switches supporting open interconnect standards such as UALink and Ethernet-based protocols.

It plans to configure the developed devices in an optimised topology to enable faster data exchange between them and conduct rack-level validation. The switch SoC supporting accelerator-centric interconnects such as UALink is expected to be available from the second half of 2027.

“Securing this project validates both our core interconnect technology capabilities and our ability to expand across the broader AI infrastructure landscape,” says Panmesia.
