Broadcom Corp. has released the StrataXGS 4 family of single-chip 65nm switches that enables 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 solution.

The fourth 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 QoS needed to implement next generation service provider networks.

The StrataXGS 4 multi-layer switch family in 65nm includes two new products: the BCM56624 and BCM56720. A third product, the BCM56820 was announced in November 2007 and completes the product family. StrataXGS 4 products offer a new solution to OEMs designing modular, stackable and fixed form factor equipment for the service provider, data center and enterprise markets.

Using a platform approach for design flexibility, StrataXGS 4 products allow OEMs to meet the requirements of on-demand networks including the seamless migration of servers and storage subsystems across the data center, while eliminating the cost of deploying and maintaining separate, disparate fabrics such as Fibre Channel, InfiniBand and others. For service providers, the StrataXGS 4 architecture facilitates a converged network by collapsing voice, video and data onto a single IP backbone that supports both wired and wireless connectivity.

Feature-rich switches
The BCM56624 is a 48-port GbE plus 4-port 10GbE solution 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. It also features large external address and security tables that scale to meet the demands of high performance equipment at the core of the network.

Meanwhile, the BCM56720 is a 4th 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. It is compatible with the new StrataXGS 4 series of products as well as products from earlier StrataXGS architectures. This switch fabric also raises the bar for stacking capability using the company's HiGig stacking protocol and service aware flow control (SAFC) to provide OEMs with high performance stackable solution.

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.

"Our StrataXGS 4 products are built upon the success of three generations of field-proven StrataXGS architecture and we anticipate that they will fuel a new class of high-density systems that would benefit next generation networks, and ultimately, millions of end-users worldwide," said Martin Lund, VP and general manager of Broadcom's network switching line of business.

Broadcom's StrataXGS 4 switch products, including the BCM56624, BCM56720 and BCM56820, are sampling in volume to customers. Pricing is available upon request.
