SemtechのTri-Edge™がAlibabaデータセンターを強化

今後数年間、データセンターのトラフィックは大幅に増加し続けるでしょう。クラウドサービス、IoT、増え続けるブロードバンドへの需要により、大規模データセンターや無線事業者は200Gや400Gへの移行を大々的に進めています。また、データセンター機器を接続するための重要な構成要素である光モジュールでも、高密度化、低消費電力化、低レイテンシー化など、これらの帯域需要に対応するための進化が求められています。

To support demand, data centers will require networking at higher speeds with higher capacity servers, switches and interconnects that use PAM4 signaling. Semtech’s Tri-Edge™ is a new approach to PAM4: Tri-Edge PAM4 clock and data recovery (CDR) technology was the first low power solution available on the market for optical communication links that addresses multiple markets, from data centers and high-performance computing (HPC), to 5G wireless fronthaul/backhaul, and links from 100m to 10km.

Alibaba Cloud: APAC's Cloud Services Leader

According to IDC, Alibaba Cloud was China’s leading provider of public cloud services by revenue in 2019. Alibaba Group is the world’s third leading and Asia Pacific’s leading IaaS provider by revenue in 2020 in U.S. dollars, according to Gartner’s April 2021 report. Alibaba Group’s goal is to build the future infrastructure of commerce, making it easy to do business anywhere. Established in 2009, Alibaba Cloud is the digital technology and intelligence backbone of Alibaba Group, offering a complete suite of cloud services to customers worldwide, including elastic computing, database, storage, network virtualization services, large-scale computing, security, management and application services, big data analytics, a machine learning platform and IoT services.

Alibaba and Tri-Edge

To enhance its Cloud offerings, Alibaba has recently completed qualification of its 200G SR4 optical module with best in class power and latency performance based on Semtech Tri-Edge CDRs (GN2558 and GN2559) and has now begun deployments.

According to Dr. Chongjin Xie, senior director and chief communication scientist at Alibaba, “The 200G SR4 optical modules leveraging Semtech’s Tri-Edge chipset fully met our exacting requirements for deployment in our data centers, including full interoperability with other optical modules and Alibaba’s switch designs. Semtech’s innovative Tri-Edge technology enables Alibaba to meet its cost, power and latency requirements for our next generation data centers.”

The deployment of Semtech’s Tri-Edge PAM4 CDRs in Alibaba’s next generation PAM4 data center represents a milestone achievement for Semtech and further demonstrates that Semtech’s Tri-Edge technology is a robust and proven solution for data center optical transceivers, enabling best in class power and latency performance. The Tri-Edge platform of analog PAM4 CDRs with fully integrated laser drivers and transimpedance amplifiers (TIAs) also lowers the cost of optical modules and AOCs. Semtech is at the initial stages of rolling out a complete Tri-Edge roadmap, which will include longer reach and higher bandwidth versions in the future.

The production released GN2558 and GN2559 is Semtech’s Tri-Edge CDR chipset that enables next generation data center connectivity over multi-mode fiber, offering the lowest power, latency and cost. These Tri-Edge CDRs have garnered multiple design wins in data center, high-performance computing and enterprise applications.
