BCM56862A1KFSBG: High-Performance 25.6 Tbps StrataXGS Tomahawk 4 Ethernet Switch Series

The relentless growth of global data traffic, driven by cloud computing, AI, and hyperscale data centers, demands a new generation of networking infrastructure. At the forefront of this evolution is the BCM56862A1KFSBG, a cornerstone of Broadcom's StrataXGS® Tomahawk® 4 Ethernet Switch Series. This device is engineered to deliver an unprecedented 25.6 Terabits per second (Tbps) of switching capacity, setting a new benchmark for performance, scale, and efficiency in the networking industry.

Built on a cutting-edge 7nm process technology, the BCM56862A1KFSBG integrates a massive number of transistors into a highly efficient package. This allows it to support up to 128 ports of 200GbE, 64 ports of 400GbE, or a flexible mix of speeds including 10GbE, 25GbE, 50GbE, and 100GbE, providing unparalleled deployment flexibility for network architects. The chip is designed to be the heart of top-of-rack (ToR), spine, and super-spine switches, forming the fabric of modern data centers.

A key innovation of the Tomahawk 4 series is its advanced shared-buffer architecture. This technology intelligently manages packet buffering across all ports, dramatically minimizing packet loss during periods of congestion and microbursts. This results in significantly improved network performance and predictability for latency-sensitive applications like high-frequency trading, AI cluster training, and distributed storage.

Furthermore, the series boasts robust advanced telemetry and analytics capabilities. It provides deep visibility into network traffic with nanosecond-level precision, enabling operators to monitor performance, detect anomalies, and troubleshoot issues in real-time. This data is critical for automating network operations and optimizing resource utilization in software-defined networks (SDN).

Power efficiency is another critical differentiator. Despite its massive throughput, the 7nm design and architectural optimizations ensure that the Tomahawk 4 switch delivers industry-leading performance per watt. This is a crucial factor for hyperscalers who manage thousands of switches and for whom operational expenditure (OPEX) related to power and cooling is a primary concern.

In essence, the BCM56862A1KFSBG is not just a switch chip; it is the engine powering the next wave of digital transformation.

ICGOODFIND: The BCM56862A1KFSBG StrataXGS Tomahawk 4 switch is a transformative force in data center networking, offering record-breaking 25.6 Tbps bandwidth, intelligent buffering for zero congestion, and deep telemetry for a self-optimizing network, all while achieving remarkable power efficiency for sustainable scaling.
