There are two primary applications for Aries Smart Cable Modules.

The first is to enable higher bandwidth and lower latency GPU-to-GPU and GPU-to-Switch multi-rack connectivity for larger AI clusters. As larger clusters of GPUs are deployed 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 certain number of GPUs due to power and thermal management constraints. Aries SCMs extend high-bandwidth PCIe 5.0. and CXL signal reach at 128 GB/s up to 7 meters to enable larger GPU clusters in a multi-rack architecture. Also, Aries SCMs improve cable routing, serviceability, and air flow with thin copper cables to maintain existing rack power and thermal density.

The second is to enable extended CXL reach for low-latency memory fabric connectivity in high-capacity in-memory compute architectures. Hyperscalers are deploying CXL memory expansion and pooling solutions to achieve higher application performance and the distances between the processor and expanded memory resources are increasing. Aries SCMs extend high-bandwidth PCIe 5.0 and CXL signal reach at 128 GB/s up to 7 meters to enable low-latency memory fabrics for scalable cloud infrastructure.
