Detailed Specifications
HPE Q1H70B HPE Ethernet 100Gb 1-Port QSFP28 Adapter
Overview
The HPE 874253-B21 is a server-class network interface adapter designed for high-bandwidth data centre and cloud applications. It delivers one QSFP28 port rated at 100 Gbps, enabling heavy east-west traffic flows, server uplinks or storage front-ends with reduced cabling. The adapter uses a PCI Express 3.0 ×16 host interface and supports advanced offload features such as RDMA and tunnel processing, helping reduce CPU overhead in virtualised and NIC-intensive environments. It installs in HPE ProLiant servers and integrates with the HPE networking and management ecosystem, making it suitable for modern rack-scale or hyper-converged deployments.
Key Features
Single QSFP28 port supporting up to 100 Gbps full-duplex
PCI Express 3.0 ×16 host interface for optimal throughput
Offload support for RDMA, tunnel processing and advanced packet handling
Designed for HPE ProLiant server integration and high-density deployments
Provides a future-proof path for 100 Gb Ethernet adoption
