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 5.0 speeds, passive PCIe DAC reach is limited to 3 meters
- Passive PCIe DACs and general-purpose AECs lack advanced cable and fleet management features essential to managing data center infrastructure
Solution: Aries PCIe/CXL Smart Cable Modules
- Aries SCMs extend high-bandwidth PCIe 5.0 and CXL signal reach beyond the rack at 128 GB/s for up to 7 meters to enable larger GPU clusters in a multi-rack architecture
- Aries SCMs improve cable routing, serviceability, and air flow with thin copper cables
- Aries SCMs offer system-wide visibility and management features with Astera Labs’ COSMOS software that enables enhanced security, quick debug, and flexible firmware upgrade.
- Aries SCMs are compatible with leading cable assembly suppliers to support multi-sourced cable solutions – enabling a flexible supply chain.
