HPE P28787-B21 X710-DA2 10Gb SFP+ Adapter

HPE P28787-B21 Intel X710-DA2 Ethernet 10Gb 2-Port SFP+ Adapter

The HPE P28787-B21 Intel X710-DA2 Network Adapter provides two 10Gb Ethernet connections for compatible HPE servers. Featuring dual SFP+ ports and a PCI Express 3.0 x8 interface, it offers a practical way to add high-speed network connectivity without replacing existing server hardware.

This stand-up PCIe adapter is designed for supported enterprise server configurations and can be used with qualified SFP+ optical transceivers or direct-attach cables. It is suitable for server networking, virtualised workloads and data centre connectivity where reliable 10Gb Ethernet links are required.

HPE P28787-B21 Technical Specifications

Why Choose the Intel X710-DA2 Adapter?

The P28787-B21 offers a straightforward solution for businesses that need additional 10Gb Ethernet capacity in a compatible server.

• Dual-port networking: Two SFP+ connections allow separate physical Ethernet links.
• PCIe 3.0 x8 interface: Designed for supported standard server expansion slots.
• Intel X710 controller: Provides enterprise Ethernet networking capabilities and supported virtualisation features.
• Flexible connections: Works with qualified optical modules and direct-attach cables.
• Low power consumption: HPE documents typical consumption of 3.3W and maximum consumption of 3.7W.

Server Compatibility and Installation

HPE P28787-B21 is intended for selected HPE server configurations. Before ordering, check the exact server model and generation against the relevant HPE QuickSpecs.

Confirm that a supported PCIe expansion slot is available and that the supplied mounting bracket fits the server chassis. The adapter is a stand-up PCIe card and cannot be installed directly into an OCP 3.0 networking slot.

After installation, use the appropriate HPE-supported firmware and drivers. Test both ports and confirm the negotiated link speeds before using the adapter in production.

SFP+ Cabling and Network Connections

The adapter uses SFP+ ports rather than RJ-45 Ethernet sockets. This allows connection to compatible switches using qualified optical transceivers and fibre cables, or suitable direct-attach copper cables.

The correct connection depends on the switch interface, cable distance and supported module specifications. Optical transceivers and cables should not be assumed to be included with the adapter.

P28787-B21 vs P28778-B21

HPE offers two Intel X710-DA2 dual-port SFP+ adapters with different physical formats:

• P28787-B21: Stand-up PCIe 3.0 x8 adapter.
• P28778-B21: OCP 3.0 adapter.

Both are designed for 10Gb Ethernet connectivity, but they use different installation formats. Check your server’s supported networking slots before choosing either model.
