BCM56960中文资料High-Density 25/100 Gigabit Ethernet StrataXGS® Tomahawk Ethernet Switch Series数据手册Broadcom规格书

描述 Description

Broadcom's BCM56960 Series, also known as the StrataXGS® Tomahawk switch series, can help build highly scalable, feature-rich, top-of-rack (ToR), blade or aggregation switches to enable cloud-scale networking. StrataXGS Tomahawk is the first series of switches to offer 25 Gb/s SerDes in support of 25/50/100GbE. It provides a total switching capacity of 3.2 Tb/s ranging from 32 ports of 100 GbE to 128 ports of 25 GbE, with the flexibility to configure port type and speed to suit any high-performance networking application.
 The StrataXGS Tomahawk switch series includes BroadView™ instrumentation, which 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. This includes extensive application flow and debug statistics, link health and utilization monitors, streaming network congestion detection and packet-tracing capabilities.
 * RoCE/RDMA functionality is only available as a technical preview and is not intended for a production environment
