Fujitsu rolls out 'most powerful' 10GbE switch IC

Fujitsu Microelectronics Europe has introduced the new MB8AA3020, a 20-port 10GbE switch IC that the company claimed is the industry's most powerful. According to the company, the new 10GbE switch was designed to meet the performance demands of high-density backplane switching for advanced TCA (ATCA) and micro TCA, blade server and data center applications. The new 10GbE switch promises 400+Gbps non-blocking aggregate switching bandwidth through 3Mbyte of proprietary, multistream shared buffer memory with on-chip 10Gbps serial SerDes.

According to the company, the chip has been designed to provide high QoS for data center and carrier networks through state-of-the-art virtualization, backward congestion management notification (BCN) and priority PAUSE features. An on-chip micro-engine drives the simple-to-use management interface. The IC, which the company said has the smallest footprint in its class, also supports the CX4 interface and adaptive equalization with on-chip SerDes.

Fujitsu said its new switch chip embeds 20 high-bandwidth, full-duplex 10Gbps ports in a single, integrated 1,156-pin FCBGA package. The 10Gbps serial ports provide a twofold advantage, according to the company: One, they eliminate the need for expensive off-chip XAUI to XFI SerDes, allowing direct connections to optical XFP modules on any port and helping to significantly reduce cost, latency, power consumption, and board space; Two, the ports reduce the routing overhead inherent in running 4 x 3.125G lanes.

The high-density switch sets new standards of delivery for enterprise, data-center and carrier-switching-systems suppliers. It promises optimal switching capacity, low latency, a wide range of switching priorities, superior security and previously unavailable congestion-management capabilities. With the 10Gbps serial interface, the new chip will cost-effectively meet the requirements for backplane switching in the ATCA, micro-TCA and blade-server environments.

With a 300ns, pin-to-pin switching latency including SerDes in cut-through mode, the chip is suitable for high-density, latency-sensitive applications. An on-chip micro-engine embedded in the chip and the 2 x 10/100/1GbE management interface provides the high-level API for switch software, Fujitsu said, reducing the amount of software development required on the board.

"With the introduction of 10Gbps connectivity for blade servers, the increasing need for high-speed aggregation in the enterprise core, and the proliferation of Ethernet into service provider networks, 10Gbps Ethernet is now becoming an important market. It will account for a significant share of Ethernet switching equipment revenues by 2010," said Peter Middleton, principal research analyst with Gartner.
