HPE 728987-B21 plug-in card with two SFP+ ports, silver bracket, green PCB

HPE Refurbished

HPE 728987-B21 10Gb 2-Port 571SFP+ Switch Module

SKU CH-49XR-JHQ8C MPN 728987-B21

Refurbished 10Gb dual-port SFP+ server adapter with PCIe x8 host interface

  • 10 Gb dual-port throughput for high-density server consolidation
  • Solarflare SFC9020 controller handles multi-core processor application loads
  • PCI Express x8 host interface enables low-latency data transfer
  • Two SFP+ slots support flexible fibre or copper connectivity
  • RoHS-5 compliant design reduces hazardous substances in the data centre

Dual 10Gb SFP+ server adapter

The HPE 728987-B21 installs in a PCI Express x8 slot and presents two SFP+ cages for 10Gb Ethernet connectivity. It targets administrators who need deterministic, low-latency networking on dense server platforms without exceeding thermal envelopes.

Plug-in card with RoHS-5 compliance

Built on the SFC9020 controller from Solarflare, the 571SFP+ adapter draws minimal power while sustaining line-rate traffic across both ports. The standard-height bracket fits common server chassis and the SFP+ cages accept a range of direct-attach cables or optical transceivers for flexible reach.

Replaces single-port or 1Gb uplinks

Moving from a single 10Gb link or legacy gigabit NIC doubles available bandwidth and adds link redundancy for virtualised workloads. The upgrade is worthwhile when east-west traffic saturates existing uplinks or when consolidation ratios demand predictable throughput per virtual machine.

Questions about this item

What host interface does the 571SFP+ adapter use and what PCIe lane width does it require?

The adapter uses a PCI Express x8 host interface, which is the lane width it requires for full 10 Gbps throughput on both ports.

What physical slot and form factor does the 728987-B21 need to install?

It is a plug-in card that fits a PCIe x8 or larger slot and provides two SFP+ cages for transceiver modules.

How is the 571SFP+ adapter installed in a server and what step is often missed?

Power down the server, open the chassis, insert the card firmly into a PCIe x8 slot, secure the bracket screw, then attach SFP+ transceivers and cables before powering on.
