Broadcom announced that Meta is now deploying the world’s highest bandwidth Ethernet switch chip in its data center network fabric — the Broadcom StrataXGS Tomahawk 4 switch series.
The Tomahawk family has consistently led the market in switching bandwidth. This has continued with the Tomahawk4 family shipping in volume for over one year, remaining the only 25.6Tbps solution in production today. Members of the Tomahawk4 family, currently in production include the Tomahawk4-50G, Tomahawk4-100G, and Tomahawk4-12.8T.
“Broadcom is pleased to support Meta and its ecosystem partners on the transition to a leading-edge 25.6Tbps networking fabric,” said Ram Velaga, senior VP and GM, Core Switching Group, Broadcom. “Our multi-year collaborative effort has resulted in the successful integration of multiple generations of the marketplace’s highest bandwidth Tomahawk switch chip into Meta’s industry-leading Wedge400 and Minipack2 networking platforms.”
The Tomahawk4 switch series currently provides the world’s lowest power per bit of throughput, enabling significant savings in operational expense and allowing for ultra-high density network equipment. The variety of SerDes speeds and bandwidth points provided by the Tomahawk4 devices, enable direct connection to high-volume 200Gbps, 400Gbps, and 800Gbps optics.
The Broadcom Tomahawk3, the Tomahawk4’s predecessor, has been shipping in production since 2018. It has been deployed in Meta’s previous and current generation platforms. The Tomahawk4 and Tomahawk3 are the foundation of numerous hyperscale data center fabrics worldwide with a broad ecosystem of ODMs, OEMs, and Network Operating System partners.
In addition to Tomahawk4, Minipack2 uses Broadcom’s 7nm Barchetta2, a 16×56-Gb/s full-duplex PHY, featuring demonstrated interoperability with Broadcom merchant switches and ASICs. This 400G/200G/100G retimer is designed with industry-leading 56-Gbps PAM4 Serdes architecture that supports greater than 30dB of insertion loss on both host and line interfaces.
