New FocalPoint 24-port 10G devices deliver 360Mpps performance as full-featured IPv4, IPv6 routers

Arastra Inc. Selects Chip for New Datacenter Switch Family

CALABASAS, CA. – Nov. 05, 2007 – Fulcrum Microsystems today announced six new members of its industry-leading FocalPoint family of 10-Gigabit Ethernet switch chips – adding high-performance routing with its FM4000-series devices. With the industry’s highest port density and lowest latency, as well as a full suite of Datacenter Ethernet functions, FocalPoint is the first switch that can enable datacenter networks to scale into the thousands of nodes.

The FM4000 chips are designed for datacenter switching platforms for high-performance computing, server and storage host interconnect, and datacenter aggregation applications. They are complete layer 2/3/4 IP switch/routers with full line-rate performance on all ports with a total throughput of 360 million packets per second. Fulcrum’s unique design technology means that the FocalPoint FM4000 chips boast the lowest latency in the industry – 300 nanoseconds as a full layer 3/4 router. This provides a highly responsive network fabric that exceeds the performance of specialty fabrics such as InfiniBand and Fibre Channel, and is well suited for the millions of messages per second performance needed for high-performance clustered-computing applications.

The 24-port density of the chip – also an industry best – enables it to be the interconnect foundation for extremely large clustered systems. When used in fat tree (or Clos) network architectures, the density and low latency mean the network can scale to 3,456 non-blocking nodes in three tiers of switching – well beyond that when additional tiers or managed under-provisioning are introduced.

“Centralized computing, networked applications and broadband mobility are driving an explosion in the build-out of highly-efficient, highly-scalable data centers, and Ethernet is the most bandwidth-efficient interconnect solution available,” said Mike Zeile, Fulcrum Microsystems vice president of marketing. “The FocalPoint FM4000 series enables switch makers to build scalable 10-Gigabit switch fabrics; we see this becoming a multi-billion dollar market opportunity in just a few years.”

FocalPoint is also the first to deliver on the promise of convergence and server and storage virtualization, with a complete set of advanced congestion management and traffic pruning capabilities, such as class-based pause, and fully-configurable access control lists (ACLs) – all of which can operate at full line rate with no performance degradation.

The first company that is announcing a product based on the FM4000 switch silicon is Arastra, a networking company founded and backed by well-known Silicon Valley veterans including Sun co-founder Andy Bechtolsheim. “The next generation of servers will have 10 Gigabit Ethernet interfaces standard on the motherboard, creating a need for cost-effective low-latency 10G Ethernet switches in the datacenter,” said Mansour Karam, director of marketing for Arastra. “Our new Arastra 7100 datacenter switch family uses the Fulcrum FM4000 chip to deliver a high-performance scalable 10G network solution that enables 10 Gigabit Ethernet to each server, improving server efficiency and utilization.”

The FocalPoint FM4000 product family consists of the FM4224, which offers 24 ports of 10-Gigabit Ethernet; the FM4212, which offers 12 10-Gigabit Ethernet ports; the FM4208, which offers eight 10-Gigabit Ethernet ports; the FM4112, which offers eight 10-Gigabit Ethernet ports, and 16 Gigabit Ethernet ports; the FM4104, which offers two 10-Gigabit Ethernet ports and eight Gigabit Ethernet ports; and the FM4103, which features two 10-Gigabit Ethernet ports and four Gigabit Ethernet ports. All of the 10-Gigabit Ethernet ports are XAUI SerDes interfaces, and can operate at 10Gbps or 10/100/1000/2500 SGMII modes. Similarly, all Gigabit Ethernet ports can operate in 10/100/1000/2500 SGMII modes.
