HPE P17518-001
SN3700cM 100 GbE 32QSFP28 ONIE Power‑to‑Connector Airflow Managed Ethernet Switch
The HPE P17518‑001 SN3700cM is a high‑density, low‑latency 32‑port QSFP28 Ethernet switch offering wire‑rate performanceacross all ports. Operating at 100 GbE per port, this 1 RU airflow‑optimized switch is ideal for Top‑of‑Rack and storage‑oriented data center environments. Compatible with NVIDIA Cumulus Linux via ONIE, it delivers flexible multi-speed configurations and supports breakout cabling for 10G/25G deployments. Engineered for flash storage acceleration and virtualized environments, this platform delivers ultra-reliable switching with zero packet loss under mixed-speed, mixed‑size traffic loads.
Features
Architected for modern server and storage networks, the SN3700cM supports configurable port speeds—from 10/25 GbE via breakout cables up to 200 GbE per port using QSFP56 modules . Delivering up to 6.4 Tbps switching capacity across 32 QSFP28 ports, it guarantees wire‑rate forwarding under all traffic conditions with zero packet loss—even at mixed frame sizes and speed mixes . Layer 3-routing support includes ECMP, BGP, OSPF, RIP, VRF, and data center bridging features like PTP, DCBx, FCoE, and RDMA over Converged Ethernet (RoCE)
Advanced Options
Engineered for demanding storage and compute fabrics, the SN3700cM delivers robust enterprise-grade performance even under heavy mixed workloads. With 6.4 Tbps switch capacity and throughput up to ~4.76 Bpps, it handles full-mesh, bursty, and latency-sensitive flows with no packet loss
