HPE829334-B21

100 GbE Omni-Path OP101 QSFP28 Single-Port Network Adapter(Refurbished)

The HPE 829334-B21 is a high-throughput refurbished Network Adapter featuring a single 100 GbE QSFP28 port basedon Intel Omni-Path Architecture. Designed for HPC clusters, AI workloads, and storage fabrics, it provides ultra-low latency and up to 100 Gbps bidirectional bandwidth over PCI Express 3.0 x8. Compatible with HPEProLiant Gen9/Gen10 servers×including DL360, DL380, DL560, DL580, ML350, and Apollo XL450×it delivers enterprise-grade performance in a low-profile form factor. Ideal for latency-critical and high-bandwidth compute environments seeking fabric speed without PCIe congestion.

Features

Operating over PCIe Gen3 x8, the OP101 controller provides wire-speed networking through a single QSFP28 interface. Built atop Intel Omni-Path architecture, it ensures deterministic latency and fabric-level integration in HPC and converged compute infrastructures. The adapter supports RDMA via OPA, enabling zero-copy data transfers across nodes with minimal CPU overhead. Its low-profile half-height form allows installation even in dense server configurations, preserving additional PCIe slots and optimizing airflow

Advanced Options

Engineered for mission-critical fabric environments, the 829334-B21 delivers consistent, high-bandwidth connectivity with minimal latency.Utilizing MSI-X interrupt processing and hardware acceleration, it reduces host CPU usage while maintaining robust throughput.
