Unveils Revolutionary 10/40 Gigabit Ethernet Switches that scale to 64,000 ports

Bristol startup Gnodal has launched its first products, aiming at industry-leading performance, port density, and low power in high performance data centres.

The GS-Series of 1RU, top-of-rack (ToR) switches use Gnodal’s own PETA ASIC, each delivering 1.5 Terabits of non-blocking, ultra-low latency switching to the data center. These chips use a new architectural design that minimizes network congestion and delivers optimum performance with minimal cost and power consumption.

The GS-Series consists of three 1RU products:

• GS7200 – 72 ports of 10 GbE SFP+
• GS4008 – 40 ports of 10 GbE SFP+ and 8 ports of 40 GbE QSFP
• GS0018 – 18 ports of 40 GbE QSFP

The family offers flexibility in network scalability as the switches can be both edge and fabric devices and in multi-chassis networks, a link or entire switch can be removed from the fabric without disrupting the rest of the network and the fabric will automatically and dynamically adjust to the changing environment without management intervention.

The GS-Series is built to scale from 72 ports in a 1RU form factor to a massive network of up to 64,000 ports by combining other members of the family to create cost-effective, ultra-low latency, highly utilized fabrics. With an initial port-to-port latency as low as 150ns and additional hops at 66ns, multi-stage networks containing thousands of ports can be assembled with an overall system latency as low as 414ns. Highly efficient arbitration techniques enable the Gnodal fabric to dynamically load-balance traffic seamlessly, thereby allowing for near 100% bandwidth utilization, even in the event of end-point congestion. These techniques also prevent Head-of-Line (HOL) blocking typically found in traditional networks when building larger fabrics comprised of multiple chassis. In addition to unprecedented levels of performance, the products are also extremely power efficient, exhibiting typical power consumption under 1.6 Watts per twinax copper port and under 2.5 Watts per optical port.

Gnodal is also announcing the opening of a wholly-owned US Subsidiary, Gnodal Inc., with offices in Palo Alto, CA to focus on the North American market.

“The GS-Series creates a truly scalable family of Ethernet building blocks, enabling network expansion to occur without the traditional latency penalties associated with adding another switch to the fabric,” said Fred Homewood, CEO, Gnodal Limited. “We looked to address some of the historic challenges of Ethernet in congestion, scalability, power, and latency and have built the GS-Series to target these high performance data center requirements with our revolutionary technology. Our products finally enable large, low latency, flat fabrics to be built by allowing Gnodal Ethernet to extend the capabilities of the Ethernet standard with minimal complexity, offering an overall more efficient use of capital equipment in the data center.”

The GS-Series are orderable now and will begin shipping by the end of this quarter.
