The StrataXGS Tomahawk II offers increased bandwidth capacity, scalability, and cost efficiency for mega data centers and high performance computing (HPC) environments. Manufactured in 16nm, Tomahawk II integrates 256 serdes running at over 25 Gbps, with large on-chip forwarding tables and packet buffer memory. With next generation BroadView instrumentation and control capabilities, Tomahawk II provides enhanced traffic load balancing, network visibility and control of traffic provisioning. Tomahawk II’s proven architecture and comprehensive feature-set will enable partners to develop and deploy solutions more quickly, accelerating the transition to high density 100GE interconnect.

"Our StrataXGS Tomahawk II comes just two years after Tomahawk with twice the bandwidth and resource capacity. We expect this to accelerate 100G adoption in the next wave of data centers, while delivering network scale and visibility for public/private cloud computing, storage and HPC fabrics," said Ram Velaga, senior vice president and general manager, Switch Products at
"The growth of data consumption has driven the need for greater bandwidth network solutions now emerging at 100G," said Bob Wheeler, principal analyst at The Linley Group. "The Broadcom Tomahawk II contains a rich feature set for switch deployments at 25GE, 50GE and 100GE that will improve both the economics and performance of cloud scale networks.
