Broadcom Corporation has announced a new 16-port 2.5 Gigabit single-chip switch based on Gigabit Ethernet (GbE) network infrastructure to deliver simultaneous 1 Gigabit Ethernet (1GbE) and 2.5 Gigabit connectivity in blade servers.

The new Broadcom StrataXGS III 2.5 Gigabit switch works in conjunction with Broadcom's NetXtreme II converged network interface controller to provide what the company says is the industry's only 2.5 Gigabit end-to-end networking infrastructure solution that is optimised for blade servers.
Broadcom asserts that IT managers need to add capacity to existing 1 GbE blade servers to effectively handle the increase in the converged network traffic (i.e. IP-based storage, clustering, management and data networking) that is creating a bottleneck in today's network.
Broadcom claims its new 2.5 Gigabit switch addresses this problem by providing more than two times the bandwidth of 1GbE, while offering features such as low latency, multi-layer switching, IPv6 routing, and deep-packet inspection, which are crucial for network management and quality of service.
"By delivering this new technology, Broadcom is responding to customer demand for a cost-effective speed upgrade to 2.5 Gigabit 'inside the box' for currently deployed 1 Gigabit blade servers," says John Mui, product line manager of Broadcom's Network Switching Business Unit.
The StrataXGS III BCM56580 provides blade server features such as cut-through switching for reduced overall system latency; Integrated SerDes and on-chip buffer and table memory to reduce bill of materials (BOM) cost and save board space; eight classes of service per port for traffic prioritisation; full IPv6 routing support.
