Detailed Specifications

HPE 879492‑B21 InfiniBand FDR / 50 Gb Ethernet 2‑Port 547FLR‑QSFP Adapter

Overview

The HPE 879492‑B21 is a high‑performance network adapter that supports both InfiniBand FDR and Ethernet at up to 50 Gb/s per port. It is designed for use in HPE servers that support FlexibleLOM (FLR) 547‑series slots, offering ultra-low latency and high throughput for clustered computing, high‑performance computing (HPC), and storage‑intensive workloads. The dual QSFP+ interface provides redundancy, load balancing, or failover capabilities. With RDMA support, it minimizes CPU overhead and maximizes data transfer efficiency in demanding environments.

Key Features

  • Dual-port QSFP+ interface for high-speed links

  • Supports 50 Gb/s InfiniBand FDR and 40/50 Gb/s Ethernet

  • FlexibleLOM 547FLR form factor for HPE ProLiant servers

  • RDMA over Converged Ethernet (RoCE) support for low-latency communication

  • Dual-port for redundancy or link aggregation
