Interop Las Vegas 2011, BRISTOL, ENGLAND & PALO ALTO, USA: Gnodal Ltd, a systems company delivering industry-leading performance, port density, and low power to the high performance data center, unveiled the GS-Series of 1RU, top-of-rack (ToR) switches built upon its own PETA ASIC, each delivering 1.5 Terabits of non-blocking, ultra-low latency switching to the data center.
Gnodal’s product family creates a paradigm shift in the way high performance data center networks are designed. Gnodal switch products derive their extreme performance capability from a revolutionary 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
Combining multiple units, the family offers the ultimate flexibility in network scalability due to the ability of the switches to act as both an edge and fabric device. Furthermore, 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 an industry-leading 72 ports in a sleek 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 a mere 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 percent 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.
