Broadcom expands market for merchant switch silicon


Las Vegas—Broadcom Corp. recently launched two products in its StrataXGS 4 next generation family of single-chip 65-nm switches.

The StrataXGS 4 multi-layer switch family in 65nm includes two products: the BCM56624 and BCM56720, which are designed to enable high-density system OEMs to build single high-density systems that meet the cost, power, performance and scalability requirements of service provider, data center and enterprise markets using a merchant silicon product.

Broadcom's 4th generation StrataXGS architecture utilizes a low power, 65nm CMOS process technology to enable the scalability necessary for data center 3.0 applications, the security required for enterprise networks, as well as the protocols and quality of service (QoS) needed to implement next generation service provider networks.

A third product, the BCM56820 was announced in November 2007 and completes the product family.

The BCM56624 is a 48-port Gigabit Ethernet (GbE) plus 4-port 10GbE product that provides carrier-class features such as IPv4 and IPv6 routing, as well as advanced metro encapsulation protocols and advanced security mechanisms such as IPFix and large access control lists (ACLs) for user and flow-based authentication.

The BCM56624 also includes advanced QoS features for service provider applications with a new dynamic adaptive memory buffer technology that provides better QoS and network performance. The BCM56720 is a fourth generation StrataXGS HiGig switch fabric that provides half a terabit of packet switching capacity on a single chip and scales to achieve multi-terabits of capacity on a single backplane.

Broadcom's SAFC technology is a key feature in all StrataXGS 4 products that makes it possible to build converged networks. SAFC provides reliable delivery of latency sensitive network traffic, such as storage, and extends priority access to time-critical applications including clustering, voice and video. Data center traffic can now be converged onto a single unified network fabric eliminating the need for separate networks, and results in a data center that is smaller, consumes less power and is easier to manage and cool.

Pricing: The BCM56624 is priced at $795/per 1000.
Datasheets: BCM56624 and BCM56720.
