Arista steps up its Ethernet challenge to Nvidia’s AI scale-up networking fabric
Arista sees Ethernet as the scale-up networking fabric of choice for AI and continues to build up its alternative to proprietary interconnects such as Nvidia’s NVLink technology.
Arista sees Ethernet as the scale-up networking fabric of choice for AI and continues to build up its alternative to proprietary interconnects such as Nvidia’s NVLink technology.
The short version
- All are based on standard Ethernet technologies: “Scale-up based on ESUN Ethernet, and scale-out based on Ethernet with UEC features,” Hardev Singh , vice president and general manager of Arista’s cloud and AI group, told Network World .
- “ Arista’s positioning contrasts with Nvidia proprietary NVLink and InfiniBand stacks,” Singh said.
- The Ethernet for Scale-Up Networking (ESUN) initiative was formed by the nonprofit Open Compute Project and promises to advance the networking technology to handle scale-up connectivity across accelerated AI infrastructure.
What happened
ESUN backers include AMD, Arista, ARM, Broadcom, Cisco, HPE Networking, Marvell, Meta, Microsoft, Nvidia, OpenAI and Oracle. The Ultra Ethernet Consortium ( UEC ), meanwhile, includes AMD, Arista, Broadcom, Cisco, Eviden, HPE, Intel, Meta, and Microsoft.
Why it matters
Its charter is to bring together industry leaders to build a complete Ethernet-based communication stack architecture for high-performance networking.
