Detailed Specifications

HPE 629138‑B21 FlexFabric 10Gb 2‑Port 526FLR‑SFP+ Adapter

Overview

The HPE 629138‑B21 is a dual‑port 10 Gigabit Ethernet network adapter designed for HPE ProLiant servers using the 526FLR mezzanine/FLR form‑factor. One adapter provides two independent 10 Gb/s SFP+ ports, enabling high‑speed uplinks or converged LAN/storage links in dense rack servers. It supports full‑line‑rate performance, advanced offload capabilities including iSCSI or FCoE, and uses standard SFP+ optics or DAC to integrate with existing fibre or copper cabling infrastructure. The card is suited for server environments where bandwidth, virtualization readiness and slot conservation are critical – for example virtualization hosts, storage servers or converged compute nodes.

Key Features

  • 2 × 10 Gb/s SFP+ ports for uplinks or twin links.

  • FlexibleLOM/FLR form‑factor (526FLR) designed for HPE servers.

  • Supports LAN, iSCSI and FCoE traffic consolidation.

  • Compatible with SFP+ optics or DAC for fibre/copper cabling flexibility.
