Detailed Specifications

HPE 877688-001

InfiniBand EDR 100 Gb/s 1‑Port QSFP28 Network Adapter

The HPE 877688‑001 (also associated with SKU/CX555A/878578‑001) is a high-performance InfiniBand EDR (100 Gb/s) single-portQSFP28 network adapter optimized for HPC, storage fabrics, and enterprise data centers. Based on Mellanox ConnectX‑5 technology and featuring a PCIe 3.0 ×16 host interface, it delivers ultra-low latency and high-throughput connectivity. Compatible with both InfiniBand and RoCE-based Ethernet fabrics, this compact “stand‑up” form factor adapter integrates seamlessly into dense server environments, making it ideal for accelerating AI/ML workloads, SAN interconnects, and scalable cluster deployments

Features

This adapter supports both InfiniBand EDR and 100 Gb Ethernet protocols via a single QSFP28 port. The Mellanox ConnectX‑5 chipset enables advanced offload features including RDMA, RoCEv2, GPUDirect, and MPI tag‑matching, significantly reducing CPU overhead and improving data transfer efficiency Designed for PCIe 3.0 ×16 slots, its low‑profile “stand‑up” design fits compact server chassis while maintaining optimal thermal performance. It's compatible with HPE ProLiant, Apollo, and similar systems certified for high-speed fabrics.

Advanced Options

Engineered to deliver enterprise-grade reliability, the HPE 877688‑001 adapter sustains consistent 100 Gb/s performance with sub‑microsecond latency—critical for HPC, storage, and mission‑critical data center tasks

Product Key Features

  • 1 × QSFP28 port supporting 100 Gb/s InfiniBand EDR and 100 GbE

  •  Mellanox ConnectX‑5 chipset with RDMA, RoCEv2, and GPUDirect

  •  PCI Express 3.0 ×16 host interface

  •  Ultra-low latency networking for high-performance computing

  •  Compact stand‑up, low-profile form factor

  •  Compatible with InfiniBand and 100 Gb Ethernet fabrics

Reliability & Performance

. Its hardware-assisted RDMA and GPUDirect features streamline data paths and reduce CPU load, enhancing overall system efficiency. Despite its high performance, the adapter consumes modest power (typically ≤ 15 W), depending on optical or DAC usage, and is designed to operate reliably under sustained loads within standard data center temperature ranges (0 °C to 55 °C)

Key Features :

    • Single QSFP28 port for 100 Gb/s InfiniBand EDR or Ethernet

    • ConnectX‑5 hardware with RDMA, GPUDirect, and MPI offloads

    • PCIe 3.0 ×16 host interface

    • Stand‑up, low-profile card design

    • Ultra‑low latency networking

    • Support for both InfiniBand and 100 Gb Ethernet fabrics
