HPE Q2P91A Ethernet 10Gb 2‑Port 530T Adapter
Overview
The HPE Q2P91A is a dual‑port 10 Gigabit Ethernet RJ‑45 copper adapter designed for servers needing high‑speed uplinks and consolidation of network traffic. It uses CAT6A (or better) cabling to deliver full line‑rate 10GBASE‑T performance, making it suitable for virtualised infrastructure and storage‑rich environments. The adapter is intended for 1U/2U rack servers and integrates into HPE ProLiant systems via a PCI Express slot, aligning well with data‑centre or private‑cloud deployments. It supports advanced offload, teaming, and SR‑IOV features to streamline deployment and reduce host CPU overhead.
