Broadcom: Ethernet switch delivers maximum port count

Think about a single chip that provides 128 10-GbE ports. Not possible right? Well, Broadcom’s latest Ethernet switch chip, the StrataXGS Trident II BCM56850, does just that — and more. The IC yields a four-times increase in network virtualization scale, and a two-times increase in forwarding and classification tables — boosting effectivity of cloud-computing infrastructure networking. Each 10-G port includes the PHY, takes less than 1 W, and supports SFP+ and XLAUI interfaces.

In addition, fabrics of BCM56850 devices can be interconnected via the HiGig2 protocol to support multi-terabit chassis designs for large-scale enterprise and service provider applications. The chip’s SmartNV feature supports Infrastructure virtualization using advanced Layer 2 over Layer 3 network overlay technologies such as VxLAN and NVGRE. The chip’s Smart-Buffer technology uses on-chip packet buffer memory. As you might expect, this is not an inexpensive device (Broadcom is not releasing pricing) and its total of 1,280-Gbit/s network bandwidth is surely worth every penny.
