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