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.
