Deliver high data throughput with multi-rack PCIe® connectivity for large AI clusters required to address the growing complexity and size of AI models.
Challenges:
- Larger clusters of GPUs are required to address the increasing bandwidth and memory demands of AI workloads
- AI infrastructure must scale GPU clusters across racks as server racks can only accommodate a limited number of GPUs due to power and thermal management constraints
- At PCIe 7 speeds, copper cables require signal conditioning to close multi-rack links
- Passive copper cables lack advanced cable and fleet management features essential to managing data center infrastructure
Solution: Aries PCIe Smart Cable Modules
- Aries PCIe Smart Cable Modules extend high-bandwidth PCIe 7 signal reach beyond the rack at 128 GT/s to enable larger GPU clusters in a multi-rack architecture
- Active electrical cables (powered by Aries PCIe Smart Retimer technology) extend reach up to 6 meters with full signal conditioning, while active copper cables (powered by Aries PCIe Smart Redriver technology) extend reach up to 3 meters with signal amplification
- Aries PCIe Smart Cable Modules offer system-wide visibility and management features with Astera Labs’ COSMOS software that enables enhanced security, quick debug, and flexible firmware upgrade
- Compatibility with leading cable assembly suppliers supports multi-sourced cable solutions and enables a flexible supply chain
