The Dell Networking H1024-OPF and H1048-OPF Edge switches deliver 100 Gbps port bandwidth with latency that stays low even at extreme scale. These 24- or 48-port 1U switches are based on Intel® Omni-Path Architecture.

Accelerate HPC workloads at any scale

The Dell Networking H-series switches are purposebuilt for HPC, delivering more networking bandwidth, lower end-to-end latency, higher message rates and better fabric resiliency, while reducing capital and operational costs.

Rapidly move priority information

Eliminate performance bottlenecks for compute and storage-intensive workloads. The Dell H-series networking switches deliver high compute traffic throughput and low end-to-end latency:

• 100Gb/s per port, 25GB/s fabric bandwidth
• 100 to 110ns port-to-port switch latency includes error detection and correction

Boost network performance with up to 1.2 terabytes of aggregate bandwidth. The Dell H-series provide hardware-based error detection and correction features, including:

• Packet Integrity Protection (PIP) allows for rapid and transparent recovery of transmission errors on an Intel® OPA link without any additional latency, compared to alternate error recovery approaches such as Forward Error Correction (FEC).
• Traffic Flow Optimization (TFO) optimizes Quality of Service (QoS) by reducing the variation in latency seen through the network by high priority traffic in the presence of lower priority traffic.
• Dynamic Lane Scaling (DLS) is designed to maintain link continuity in the event of a failure of one of more physical lanes (each link contains four lanes). This enables a workload to continue to completion.

Reach more nodes faster in fewer hops

Dell Networking H-series, 48-port fabric switches can dramatically lower fabric acquisition costs and simultaneously reduce space and power requirements.

The Dell H1048-OPF 48-port switch delivers a 33% increase in ports per switch compared to a standard 36-port switch.

Extreme scalability and flexibility

Scale systems confidently with networking engineered for top performance today, and flexibility for tomorrow's compute and storage requirements. The H-series 48- port edge switch scales up to 27,648 end points at full bi-sectional bandwidth in a 5-hop fat-tree edge/core design, up from the 11,664 nodes that was possible with a standard 36-port switch.
