Detailed Specifications

HPE 878578-001

InfiniBand EDR / 100 GbE QSFP28 Single‑Port Network Adapter

The HPE 878578‑001 (also known as 872725‑B21/CX555A) is a high-performance InfiniBand EDR / 100 GbE adapter equipped witha single QSFP28 port. Built on Mellanox ConnectX‑5 technology, this compact adapter delivers ultra-low latency and up to 100 Gb/s throughput. Designed for high-performance computing, storage clusters, AI/ML workflows, and enterprise fabrics, it optimally balances speed with minimal CPU overhead. Its stand‑up low-profile form factor ensures compatibility with dense rack deployments and a wide range of HPE ProLiant Gen9/Gen10 servers and storage systems.

Features

This adapter supports the IBTA 1.3 InfiniBand EDR standard and operates at 100 Gb Ethernet via RoCEv2 on a single QSFP28 port. With PCIe Gen3 ×16 interface, advanced features such as RDMA, GPUDirect, and MPI tag‑matching reduce CPU utilization and improve throughput in virtualization and storage environments. Its compact “stand‑up” low-profile design provides flexible deployment in servers where airflow and space are constrained. Compatible with InfiniBand EDR/FDR switches and 100 Gb Ethernet fabrics, this single-port card delivers enterprise-level connectivity in a streamlined footprint.

Advanced Options

This adapter delivers enterprise-grade performance with consistent 100 Gbps throughput and sub‑microsecond latency—ideal for HPC clusters and data center fabrics. The hardware offload features significantly reduce host CPU load,
