Building on its widely deployed StrataXGS Trident and StrataDNX products, the new StrataXGS Tomahawk Switch Series is the industry's highest performance Ethernet switch, delivering 3.2 Terabits per second (Tbps) switching capacity, unparalleled port density and SDN-optimized engines in a single chip.

With more than 7 Billion integrated transistors, the StrataXGS Tomahawk Series enables the transformation of next-generation cloud fabrics to all-25Gbps per-lane interconnect, increasing link performance by 2.5X.

With dense 100GE connectivity and authoritative support for new 25GE and 50GE protocol standards, the StrataXGS Tomahawk Series significantly bolsters the bandwidth capacity, scalability, and cost efficiency of today's mega data centers and high performance computing (HPC) environments.

By deploying StrataXGS Tomahawk based switches, data center networks currently running 10GE at the top-of-rack (leaf) level and 40GE at the end-of-row (spine) level can upgrade to 25GE and 100GE interconnect, respectively, to accommodate growth in distributed server/storage workloads without increasing network equipment footprint or cabling complexity. A three-tier data center fabric of StrataXGS Tomahawk switches, using standard, compact, CAPEX-efficient form factors, can deliver over 15X higher network bandwidth capacity3.

In lieu of upgrading server-to-switch connections to 40GE, a StrataXGS Tomahawk based network driving 25GE to the server reduces cabling elements within the rack by as much as 75 percent, while quadrupling the number of server and storage nodes that can be interconnected in a leaf-spine topology.

This dual-pronged improvement in bandwidth efficiency and port density compared to existing 40GE solutions gives modern data centers unprecedented ability to scale out their networks and achieve significant return on investment.

Optimized for Software Defined Network (SDN) application ecosystems, Broadcom's new BroadView instrumentation feature set enables data center operators to have full visibility of network and switch-level analytics.

With extensive application flow and debug statistics, link health and utilization monitors, streaming network congestion detection and packet tracing capabilities, the StrataXGS Tomahawk Series provides operators the telemetry to troubleshoot large-scale networks, apply controls for optimal performance, respond to potential problems before they happen and drive down OPEX.

Featuring new FleXGS packet processing engines, the StrataXGS Tomahawk Series enables operators to adapt to changing workloads and control their networks, with an extensive suite of user configurable functions for flow processing, security, network virtualization, measurement/monitoring, congestion management and traffic engineering.

Among other benefits, FleXGS engines provide in-field configurable forwarding and classification database profiles, more than 12X greater application policy scale compared to previous generation switches, increased flexibility of packet lookups and key generation, and rich load balancing and traffic redirection controls. All these configurable capabilities are accessible to the network control plane via industry-proven software APIs and come without sacrificing network data plane throughput or latency.
