What port configuration does HPE R3A97-63001 provide?

32 QSFP28 ports supporting 100GbE native with 40GbE breakout compatibility. Each port delivers full-duplex wire-speed, enabling 6400Gbps bidirectional throughput ideal for spine roles in 100G fabrics.

What is the switching performance of this switch?

6400Gbps non-blocking switching capacity with 5714Mpps forwarding. Sub-450ns latency ensures lossless RoCEv2 for AI training clusters, supporting millions of flows with Spectrum-3 ASIC architecture.

Does it support open networking operating systems?

Yes, ONIE bootloader allows installation of Cumulus Linux, SONiC, or other ONIE-compatible NOS. This provides disaggregated control plane flexibility for cloud providers avoiding vendor lock-in.

What airflow direction is used?

Power-to-connector (back-to-front) airflow optimizes cooling for high-density datacenter racks. Intake fans pull air across PSUs first, then components, maintaining optimal temperatures under full load.

Is it suitable for AI/ML workloads?

Optimized for RoCEv2 fabrics with adaptive routing, PFC, and ECN. Handles GPU-direct traffic patterns with zero packet loss, scaling to thousands of nodes in large-scale training clusters.

What redundancy features are included?

Dual hot-swappable PSUs with 1+1 power redundancy, redundant fan modules, and MLAG for hitless failover. Supports hitless ISSU for zero-downtime upgrades in production fabrics.
