HPE 879491‑001 Ethernet InfiniBand 40/50 Gb 2‑Port 547FLR‑QSFP Adapter
Overview
The HPE 879491‑001 is a high‑bandwidth network adapter engineered for demanding server environments such as HPC, AI compute clusters or storage‑fabric nodes. It features two QSFP‑type ports supporting either 40 Gb/s or 50 Gb/s link speeds, enabling extremely high throughput for inter‑rack or server‑to‑server connectivity. The adapter installs in the dedicated 547 FLR slot of supported server platforms, preserving standard PCIe expansion slots. Advanced offload features and low‑latency architecture make it suited for both InfiniBand and Ethernet fabrics. With support for dual high‑speed uplinks and flexible media, it enables direct server interconnect or uplink to aggregation switches in data‑centre topologies.
