Unified Testing and Realistic Workload Emulation for AI Fabrics
The AresONE 1600GE is a scalable 1.6T Ethernet AI workload emulation platform designed to validate next‑generation AI fabrics operating over emerging 224G SerDes lanes from 200GE to 1600GE. It unifies physical‑layer validation, AI workload emulation, and traffic and protocol testing in a single platform. Running Keysight Data Center Builder (KAI DC Builder) on AresONE 1600GE enables Collective Benchmarks to evaluate AI cluster communication performance and assess the network’s impact on job completion time, isolation, load balancing, and congestion control. Together, AresONE 1600GE and KAI DC Builder emulate realistic AI workloads, including multiple full‑stack RoCEv2 connections and diverse collective communication patterns.

Frequently Asked Questions
Validating AI fabrics built on 224G SerDes requires more than traditional traffic generation. As AI workloads scale, network devices must handle higher switch radix, microburst driven congestion, and intricate collective communication patterns. Testing needs to reflect real AI workload behavior, not just synthetic traffic, to ensure fabrics perform correctly both pre and post deployment.
AresONE 1600GE addresses these challenges with realistic AI workload emulation, including full stack RoCEv2 connections and collective communication patterns. By running KAI Data Center Builder software on the AresONE 1600GE hardware platform, engineers can evaluate AI cluster communication performance, measure the network’s impact on job completion time, and assess performance isolation, load balancing, and congestion control. This enables teams to fine tune next generation AI fabrics under realistic conditions, reducing deployment risk and improving test accuracy.
At 1.6T Ethernet speeds over 224G electrical lanes, slight impairments in optical or electrical paths, PCS behavior, or Forward Error Correction (FEC) implementation can impact reliability at scale. Validating physical layer integrity requires visibility into link behavior, coding accuracy, and FEC correction events—not just basic bit error metrics.
AresONE 1600GE provides comprehensive physical layer validation, including optical and electrical link testing, FEC and physical coding behavior analysis, PCS lane statistics, symbol error injection, and BER/FLR measurements across all supported speeds from 200GE to 1600GE. This helps engineers detect issues early, correlate physical layer performance with protocol behavior and AI workload outcomes, and ensure devices are ready for real world AI data center environments.
As AI data centers expand, the ability to test multiple high speed Ethernet configurations — 200GE, 400GE, 800GE, and 1600GE — is essential for validating a wide range of GPUs, NICs, accelerators, and switching devices. Labs need a platform that supports flexible topologies, high density port configurations, and realistic workload profiles.
AresONE 1600GE delivers this through its high density OSFP 1600 hardware architecture, supporting fan out configurations of 1×1600GE, 2 x 800GE, 4 x 400GE, or 8×200GE over 224G SerDes lanes. Combined with Keysight Data Center Builder (KAI DC Builder) software, it enables scalable AI workload emulation and collective benchmarks across large clusters. The rack-mount platform supports automated, repeatable testing, seamless integration across lab and data center environments, and unified physical layer through Layer 2/3 validation — allowing teams to scale test coverage without adding extra hardware or complexity.
