HPE 764617-B21

544+QSFP 10 Gb/40 Gb 2‑Port Network Card

The HPE 764617‑B21 Network Adapter is a high-capacity, dual-port card engineered for speed and flexibility. It supports both InfiniBand FDR and 40 Gb Ethernet protocols, providing up to 56 Gbps total bi-directional throughput per port. This module is ideal for HPC clusters, data center connectivity, and latency-sensitive workloads. The QSFP interface ensures support for both 10 Gb and 40 Gb links, while its dual-port design offers redundancy or high-density networking options. Refurbished and tested, it delivers enterprise-level performance at a cost-effective price—perfect for scaling infrastructure or upgrading existing networks.

Features

This adapter offers versatile dual‑mode operation: running as either InfiniBand FDR for sub-microsecond latency or 40 Gb Ethernet (40GBase‑X) for high data throughput. Each QSFP port can auto-negotiate to 10 Gb or 40 Gb speeds depending on media and configuration, making it flexible in mixed‑speed environments. The card receives minimal power (approx. 13.6 W typical / up to 14.2 W max), helping reduce thermal and energy overhead in dense rack servers . Fully MSA-compliant, it supports standard QSFP modules and cabling, enabling quick integration with HPE ProLiant and Apollo platforms.

Advanced Options

Built to deliver consistent performance in demanding networking environments, the P/N 764617‑B21 card is ideal for high-performance computing and enterprise grade Fibre Channel or Ethernet deployments. Its support for InfiniBand FDR ensures ultra-low latency messaging and throughput
