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
