Gennembrud for 100Gbit/s datakommunikation via kobber-interkonnektering

Aquantia har i samarbejde med GLOBALFOUNDRIES udviklet kobberinterkonnekterings-teknologi, der understøtter datahastigheder på 100 Gbit/s, hvilket kan sænke omkostninger i forbindelse med opkobling til high-performance datacentre (in english).

Aquantia’s technology delivers a quantum leap in data rate performance over a single lane of copper previously believed to be solely the realm of optical techniques. The availability of this technology will enable system vendors and data center operators to push towards higher performance and newer topologies in hyperscale architectures while keeping the reliability, low-cost and ease-of-use of electrical-based interconnects.

QuantumStream technology is aimed at inter and intra rack connectivity up to a few meters complementing longer reach optical connectivity solutions used in hyperscale data centers.

- To date, industry watchers have projected that only optical connectivity will serve the needs of 100Gbit/s and beyond. This presents a huge barrier since optical technologies are intrinsically higher cost, explains Faraj Aalaei, CEO of Aquantia.

- Our expertise in complex high-speed copper transceivers, coupled with the legacy of robust SerDes leadership with GLOBALFOUNDRIES’ 14nm technology will enable a continuous roadmap to the required 100G connectivity and provide our customers with the best combination to differentiate and stay ahead of evolving marketplace demands.

GLOBALFOUNDRIES has over 20 years of deep technical expertise in high-speed Serializer-Deserializer (SerDes) design. A SerDes integrated circuit is a fundamental building block responsible for the transport of data between switches, servers, routers and storage equipment in data centers and IT environments, over a variety of channels such as optical fibers, electrical copper cables, and backplanes.

GLOBALFOUNDRIES’ FX-14 ASIC platform, designed on the company’s most advanced 14nm Power Plus (LPP) process technology, delivers an optimized IP portfolio, including the latest generation of SerDes, which is capable of transporting data at speeds of up to 56Gbit/s.

Under the agreement, GLOBALFOUNDRIES provides access to its 56Gbit/s IP core to Aquantia’s team of experts. Aquantia combines the 56Gbit/s IP core with its patented Mixed-Mode Signal Processing (MMSP) and Multi-Core Signal Processing (MCSP) architectural innovations of high-speed interconnect over copper, which it has developed over the past decade to deliver a unique 100G interconnect high-performance SerDes solution.

In addition, Aquantia will provide access to its QuantumStream technology to GLOBALFOUNDRIES for incorporation into its customers’ ASICs, therefore expanding the ecosystem of solutions supporting this revolutionary interface.

The collaboration seeks to break through the perceived technical barriers in continuing the current electrical connectivity roadmap to 100Gbit/s. In addition, Aquantia’s QuantumStream technology is easily leveraged to deliver up to 400Gbit/s of bandwidth on conventional DAC cables, resolving one of the most significant challenges facing the networking and data center industries today.

An analysis of the deployment of switch and server connectivity in hyperscale data centers shows a large concentration of them are within a few meters. According to Crehan Research, the majority of direct server and storage Ethernet network connections in hyperscale data centers are currently within 3 meters.

Since interconnect solutions that are optimized for hundreds of meters or even a couple of kilometers would not be adequate for a few meters, this leads to the need for complementary solutions for connectivity over short-reach applications and long-reach connections.

Traditionally, electrical interconnects have delivered the lowest-cost and -power options for the short reach space whereas optical solutions have been deployed in longer reach applications thanks to low-loss of optical fibers.

Responding to a sweeping industry trend toward higher density switch and server configurations, a number of optical solutions have already been proposed for 100G. Aquantia’s QuantumStream technology, a complementary 100G solution for mass server and switch connectivity at shorter reaches over copper lane implementations is now possible for the first time.

- To meet the tremendous growth in bandwidth and data demands, GLOBALFOUNDRIES is continuing its commitment to investing in network and technology enhancements including a best-in-class high-speed SerDes solution that will bring tremendous benefits to our customers, says Mike Cadigan, senior vice president of global sales and business development at GLOBALFOUNDRIES.

- Aquantia’s innovative design expertise in high-speed copper interconnect technologies, combined with our world-class SerDes IP portfolio, will enable the continuation of electrical interconnect paradigms for hyperscale data centers.
