Solving AI’s Three Big Problems Through Photonic Fabric™ Technology
By Uday Poosarla, Senior Director, Product Management, Photonic Fabric Business Unit, Marvell
Three critical constraints are shaping the evolution of AI infrastructure:
- The scale-up network: Scale-up domains are increasing in size, processor count, and complexity. As these systems extend beyond a single rack, maintaining high bandwidth and low latency becomes significantly more challenging.
- The memory wall: There is a widening gap between the memory capacity and bandwidth AI workloads require and what existing memory subsystems can deliver efficiently.
- Performance per watt: Energy efficiency is becoming a defining constraint, both for controlling operating costs and staying within data center power limits.
Together, these challenges point to a common problem: the increasing difficulty of moving data efficiently across AI systems, from compute to memory across the scale-up domain.
The Marvell® Photonic Fabric™ technology platform addresses these challenges by combining the advantages of optical interconnect with system-level design innovation.

Dr. Hamid Azimi Wins ISIG Lifetime Hall of Fame Award
By Michael Kanellos, Director of Content Marketing, and Vienna Alexander, Marketing Content Professional
At the International Semiconductor Industry Group (ISIG) Executive Summit in Silicon Valley, Marvell Senior Vice President of Foundry and Advanced Packaging Dr. Hamid Azimi received the 2026 Hall of Fame award. This recognition celebrates leaders whose lifetime contributions have had a lasting impact, significantly advancing the semiconductor industry.
Over a career spanning more than 30 years, Dr. Azimi has led teams that have achieved numerous industry-leading advances in packaging. He was part of the team that developed the first flip-chip packaging with Ajinomoto Build-Up Film (ABF) substrates, a combination that enables engineers to design packaging containing far more and much smaller interconnects to improve signal integrity and power flow. Hamid and his team also enabled EMIB (Embedded Multi-Chip Interconnect Bridge) technology from scratch to high volume manufacturing. EMIB is the first 2.5 interposer-less panel level technology that enables ultra-large packages for AI data center products; he also has been a pioneer in glass substrates, a potential technology that could further enhance the capability of future generations of devices. Originally from a small village that “probably doesn’t even register on Google Maps,” Dr. Azimi holds over 40 patents. He earned a Ph.D. and M.S. in Materials Science from Lehigh University and a B.S. in Materials Engineering from Sharif University of Technology.

Scale-up Network Solutions for AI Infrastructure
By Preet Virk, Senior Vice President and General Manager, Photonic Fabric Business Unit
Modern AI infrastructure is built around multi-rack systems where thousands to tens of thousands of accelerators operate as a single logical compute element. As agentic AI and Mixture of Experts (MoE) models accelerate AI adoption, they are driving unprecedented scale and communication demands across data center infrastructure. These systems are connected by scale-up and scale-out networks that must deliver high bandwidth, low latency and efficient power. As these networks extend across racks, maintaining that performance becomes a primary challenge.
As AI systems grow in complexity and scale, the network becomes the backbone of the compute system. Large-scale clusters require massive XPU-to-XPU communication, driving an evolution beyond legacy protocols like PCIe® to encompass UALink™ (Ultra Accelerator Link), ESUN (Ethernet scale-up networking) and NVLink.
Meeting these requirements demands a new approach to connectivity. Marvell provides a comprehensive AI connectivity portfolio spanning scale-up, scale-out, scale-across and DCI (data center interconnect) network architectures. For scale-up networking, Marvell delivers copper and optical interconnects connecting XPUs, switches and memory. Within the rack, Marvell copper solutions provide low-latency, power-efficient short-reach connectivity, while Marvell optical interconnects enable high-performance scaling beyond the rack. This enables XPUs to operate as a more efficient, unified system as scale-up domains expand.

MACsec: A Shift in Security for Scale-across Networking
By Joseph Chon, Senior Director, Product Marketing, Data Center Interconnect, Marvell
MACsec is moving to the module in scale-across networks.
Media Access Control security (MACsec) is a foundational technology for protecting data in motion. It encrypts and authenticates Ethernet traffic to guard against eavesdropping, denial-of-service attacks, intrusion and other security threats while also strengthening overall data integrity. Embodied in silicon, MACsec further establishes a robust root of trust for managing encryption keys and securing the boot process.
What’s changing is where the silicon for delivering MACsec gets located.
To date, the MACsec circuitry for long-distance scale-across networks has typically been embedded in the switch ASIC, where space and silicon real estate are at an absolute premium. Embedding MACsec into the tight confines of the ASIC raises the cost of integrating the technology. It also makes infrastructure less flexible: some upgrades require taking the system offline, reducing overall capacity.
