Broadcom Switch Enables First Simultaneous 1 Gigabit Ethernet and 2.5 Gigabit Server Blade Connectivity Using Existing GbE Infrastructure

via PRNewswire

GARDEN GROVE, Calif., April 18 /PRNewswire-FirstCall/ -- (Server BladeSummit) Broadcom Corporation (Nasdaq: BRCM), a global leader in semiconductorsfor wired and wireless communications, today announced a new 16-port2.5 Gigabit single-chip switch that uses existing Gigabit Ethernet (GbE)network infrastructure to deliver simultaneous 1 Gigabit Ethernet (1GbE) and 2.5 Gigabit connectivity in blade servers. The new Broadcom(R) StrataXGS(R)III 2.5 Gigabit switch works in conjunction with Broadcom's popular NetXtreme(R) II converged network interface controller (C-NIC) to provide the industry's only 2.5 Gigabit end-to-end networking infrastructure solution that is optimized for blade servers.

IT managers need to add capacity to existing 1 GbE blade servers toeffectively handle the increase in the converged network traffic(i.e. IP-based storage, clustering, management and data networking) that iscreating a bottleneck in today's network. Broadcom's new 2.5 Gigabit switch addresses this problem by providing more than two times the bandwidth of 1 GbE,while offering features such as low latency, multi-layer switching, IPv6routing, and deep-packet inspection, which are crucial for network managementand quality of service (QoS).

"By delivering this new technology, Broadcom is responding to customer demand for a cost-effective speed upgrade to 2.5 Gigabit 'inside the box' forcurrently deployed 1 Gigabit blade servers," said John Mui , Product Line Manager of Broadcom's Network Switching Business Unit. "The real value is that Broadcom is enabling the additional speed, while protecting our customers' IT investment by utilizing the existing backplane hardware."

Announced today is the StrataXGS III BCM56580, a 16-port 2.5 Gigabit/1GbEmulti-layer single-chip switch that includes 4 ports of 10GbE. The device features auto-negotiation of both 1GbE and 2.5 Gigabit, which allows each portto simultaneously support either 1 GbE or 2.5 Gigabit speeds, and enables individual deployment of blades in a plug-and-play fashion. Also featuredwithin the BCM56580 is the Broadcom ContentAware(TM) engine, which providesdeep-packet inspection (Layers 2 - 7), allowing the switch to identify andprioritize various types of traffic including IP-based storage, clustering, management and data networking.

The StrataXGS III BCM56580 provides key features required for blade servers including:
