#OFC24: Intel's Optical I/O Chiplet Co-Packaged with Server CPU

At #OFC24, Intel demonstrated an advanced Optical Compute Interconnect (OCI) chiplet co-packaged with a prototype of a next-generation Intel CPU.

The OCI chiplet contains a single Silicon Photonics Integrated Circuit (PIC) with integrated lasers, an electrical IC with RF Through-Silicon-Vias (TSV), and a path to incorporate a detachable/re-usable optical connector.  The 4 Tbps bidirectional chiplet is compatible with PCIe Gen5, supporting 64 lanes of 32 Gbps data in each direction over 10’s of meters, realized as eight fiber pairs each carrying eight DWDM wavelengths.

Christian Urricariet, Senior Director of Product Marketing, from Intel's Silicon Photonics Products Division explains:

- Intel demoed its first Optical Compute Interconnect(OCI) chiplet, a high-density optical interconnect solution for compute elements like CPU or GPU clusters.

- The capabilities of the OCI chiplet, which can support up to 4 terabits per second bi-directionally, and its integration with next-generation Intel CPUs.

- The performance of the OCI technology, showcasing its ability to run over standard, widely deployed single-mode fiber (SMF-28), without requiring Polarization Maintaining Fiber (PMF) like other technical approaches in the market.

Digital Realty to Host NVIDIA AI Supercomputer in Denmark

Digital Realty has been selected to host one of the world's most powerful AI supercomputers at an AI-ready data center in Copenhagen, Denmark. 

The Novo Nordisk Foundation and the Export and Investment Fund of Denmark (EIFO) are joining forces to provide Danish researchers from both the public and private sectors with access to an NVIDIA-powered AI supercomputer. This initiative will not only offer them the supercomputer's capabilities but also access to NVIDIA's software platforms, training, and expertise.

This advanced NVIDIA DGX SuperPOD supercomputer boasts 191 NVIDIA DGX H100 systems, which incorporate more than 1,500 NVIDIA H100 Tensor Core GPUs. These are linked together using NVIDIA's Quantum-2 InfiniBand networking technology. Additionally, the supercomputer comes with NVIDIA AI Enterprise software, which includes pretrained models, optimized computing frameworks, and libraries for faster data science. Housed within Digital Realty's state-of-the-art, AI-optimized infrastructure, this powerful setup empowers the newly established National Center for AI Innovation in Denmark. This center aims to push forward research and innovation across various sectors such as healthcare, life sciences, and climate studies.

The supercomputer will be housed in one of Digital Realty's state-of-the-art data centers in Copenhagen, which have been powered by 100% renewable energy since 2020. Digital Realty has more than one gigawatt of renewable energy under contract globally and is a signatory to the EU Climate Neutral Data Centre Pact, committing to carbon neutrality for its European data centers by 2030.

Chris Sharp, Chief Technology Officer at Digital Realty, commented, "Digital Realty is at the forefront of crafting the digital future, transcending mere infrastructure development to become architects of tomorrow. Our commitment to delivering state-of-the-art, AI-ready infrastructure is not just about accelerating AI adoption – it's about pioneering the next wave of innovation. We envision Digital Realty as more than a meeting place for AI; we aim to establish it as the premier nexus for private AI, where enterprises and data converge. Here, scientific breakthroughs are realized, industries are transformed, and the future is molded by the synergy of technology and imagination."

"We are delighted to be working with Digital Realty," said Mads Krogsgaard Thomsen, Chief Executive Officer of the Novo Nordisk Foundation. "With their superb track record of operational excellence and tangible commitment to sustainability, they are the ideal partner to host the supercomputer and help take this exciting initiative forward."

Dell'Oro: Campus NaaS market to double in 2024

Dell'Oro Group projects that Campus Network as a Service (CNaaS) revenues will double in 2024 in the midst of a LAN equipment market contraction.

"Campus NaaS uses cloud-managed equipment to simplify LAN connectivity for enterprises," said Siân Morgan, Wireless LAN Research Director at Dell'Oro Group. "CNaaS vendors are changing the way companies consume Wi-Fi in their network, and we expect this model of service to grow faster than the overall LAN market for the next five years. CNaaS startups such as Nile, Join Digital, and Shasta Cloud have begun partnering with service providers to extend the reach of their innovative offers.

"Public Cloud-Managed LAN equipment has always grown faster than the overall LAN equipment market, but that growth differential is narrowing. The next wave of high growth in the LAN equipment market will come from CNaaS. We've identified 13 vendors with CNaaS, and with the new CNaaS Service Packs that HPE has released, the company has the largest breadth of available offers," add Morgan.

Additional highlights from the Campus NaaS and Public Cloud-Managed LAN Advanced Research Report:

  • On average, unit pricing for LAN equipment is forecasted to decline over the next five years now that lead times have returned to normal.
  • Recurring license revenues outgrew expectations in 2023, promising to contribute considerable revenues to both Public Cloud-Managed LAN and to CNaaS.
  • The market has converged on three types of Campus NaaS offers: Enabler, Turnkey, and LAN-as-a-Utility. Each type of Campus NaaS has different characteristics and growth drivers.
  • The CNaaS model is expected to flourish in two particular use cases which benefit from a recurring cost structure and a fully-managed network.
