描述 Description

Server interfaces in the enterprise and service provider data centers are starting to transition from 10 to 25GbE. At the same time SDN is taking hold in these market segments, bringing with it many new requirements such as novel?overlays, instrumentation and telemetry. Trident 3?introduces dataplane programmability and 25 Gbps SerDes?into the industry-leading Trident? line to address these evolving markets.??With support for up to 32 ports of 100GbE, the StrataXGS? Trident 3?switch series can be used to build highly scalable, low-power, feature-rich Top-of-Rack (ToR), Aggregation and Spine switches. The programmable pipeline allows new features to be added after deployment by means of in-field upgrade, providing capex investment protection for operators. Trident 3 programmability enables the latest, cloud-scale?instrumentation and telemetry features, for example in-band telemetry. Trident 3 programmability can also be used to add new software-defined forwarding?and database reconfiguration features.??In addition, fabrics of BCM56870?devices can be interconnected via the HiGig2? protocol to support multi-terabit chassis designs for large-scale data center, enterprise and service provider applications. The StrataXGS Trident 3 switch with integrated FleXGS? Programmability technology has been designed to address performance, capacity and service requirements for next-generation data centers and cloud computing applications.
