HPE P37219-B21

InfiniBand FDR / Ethernet 10 Gb / 40 Gb 2‑Port 544+ FLR‑QSFP Network Adapter

The HPE P37219‑B21 is a dual‑port Network Adapter offering 40 Gbps InfiniBand FDR and 10 GbE Ethernet connectivity via QSFP interfaces, in a flexible FLR‑QSFP PCIe form factor. Based on Mellanox ConnectX‑3 Pro generation, this card supports both protocols, enabling converged fabrics in HPE Gen8–Gen10 servers. Ideal for mixed-speed HPC clusters, virtualized environments, or storage fabrics, the adapter delivers dual‑lane redundancy and high throughput for demanding workloads.

Features

Featuring two QSFP ports operating up to 40 Gbps each (for InfiniBand FDR) or 10 Gbps Ethernet (with appropriate breakout), the adapter uses PCIe 3.0 ×8 FLR-compatible interface to enable streamlined installation in blade or server systems. It supports link speeds of 10 GbE or FDR via QSFP modules or DAC/AOC cables, allowing network flexibility. Power consumption typically ranges around 8.7 W (max 10.6 W) for Ethernet mode and ~13.6 W (max 14.2 W) for full InfiniBand operation Compatible with Linux, VMware, and Windows environments via mlx4 drivers, the adapter features onboard virtualization offloading, link aggregation, and status indicators via DDM-based diagnostics.

Advanced Options

Built with the proven ConnectX‑3 Pro architecture, the P37219‑B21 delivers reliable low‑latency connectivity for HPC and converged networking needs. The ability to run both InfiniBand FDR and Ethernet on the same hardware offers deployment flexibility and simplified inventory.
