Broadcom Corp. has released a 1010GbE switch that provides 240Gbits of multilayer switching capacity on a single chip. The chip uses 65nm process technology to achieve low power consumption and thus enable 'green' data centers. Broadcom says its new 10GbE switch provides data centers with greater density at a lower power. This enables cooler operations that better support a fluctuating volume of users due to rich multimedia content associated with Web 2.0, online video-on-demand, social networking and interactive gaming.

BCM56820 is the latest member of the StrataXGS Ethernet switch family and supports the scalability necessary for Web 2.0 support, the reliability and security required for enterprise applications, as well as the bandwidth and quality of service (QoS) needed to deliver rich multimedia content such as IPTV.

One key feature of the BCM56820 is Broadcom's service aware flow control (SAFC) technology, which enables data center Ethernet (DCE). In this converged 10GbE-based fabric, SAFC greatly improves performance in data centers by ensuring that there is no loss of data on the network. It guarantees reliable delivery of sensitive network traffic such as storage, while extending priority access to time-critical applications like clustering and video.

Broadcom's StrataXGS BCM56820 series includes two new products: BCM56820 and BCM56821.

The series features Broadcom's multistage ContentAware engine supporting deep packet inspection and classification for traffic flow identification and policy application. The device also offer Layer 2 (L2), VLAN switching and Layer 3 (L3) routing support including IPv6 and advanced QoS for converged networking applications including per-priority pause/priority flow control (PPP/PFC). With improved Broadcom HiGig stacking technology, the series enables increased scalability. Other features include non-blocking performance, switching over 375 million packets per second.

Available in 24-port and 20-port versions, each port of the device can support Fast Ethernet, GbE, 2.5GbE or 10GbE connectivity

The BCM56820 low power 10GbE chip is currently shipping to early access customers. Pricing is available upon request.

The product features a widely adopted software API, which is common across the entire product line and supported by multiple third-party software vendors, as well as Broadcom's FASTPATH application layer software. Reference designs are also available.
