Network interface card HP Enterprise 870548-B21-RFB 10GbE SFP+

HP Enterprise 870548-B21-RFB 10GbE SFP+ network interface card is a PCIe adapter designed for server and data center deployments requiring high-speed Ethernet connectivity. The card provides two SFP+ ports for 10 Gigabit Ethernet links and is intended to integrate into virtualized environments, storage networks and clustered systems to increase bandwidth, lower latency and improve overall throughput.

Advantages

This HP Enterprise 10GbE SFP+ adapter delivers consistent low-latency performance for demanding server workloads and supports hot-plug deployment in PCIe slots. The dual SFP+ ports enable flexible connections to fiber or copper transceivers, while the card’s design emphasizes compatibility with enterprise-class servers and operating systems. Built to handle high I/O and concurrent network sessions, it helps optimize virtualization, storage traffic and east-west data flows within racks or between nodes.

Suitable for

• Server virtualization and hyper-converged infrastructure
• Storage area networks (iSCSI, NFS) and backup systems
• High-throughput database and application servers
• Clustered computing and high-availability setups
• Aggregating uplinks in top-of-rack or leaf-spine architectures

Key specifications

• Interface: PCI Express (PCIe) card for server slots
• Network speed: 10 Gigabit Ethernet per port
• Ports: Dual SFP+ ports for fiber or compatible copper transceivers
• Form factor: Low-profile bracket support for rack servers
• Protocol support: Standard Ethernet networking protocols and offload capabilities for improved CPU efficiency
• Power and thermal: Designed for continuous server operation with enterprise thermal characteristics

How to use

Install the card into an available PCIe slot on a powered-down server following the server manufacturer’s hardware procedures. Secure the bracket, connect compatible SFP+ transceivers or direct-attach cables to the ports, and attach the network cabling. Power on the system and verify BIOS/UEFI detection of the adapter. Install vendor- or operating system-provided drivers and firmware updates, then configure network settings via the server OS or management software to allocate IP addresses, bonding or VLANs as required.

Usage recommendations

For optimal performance, use certified SFP+ transceivers or passive/active direct-attach cables that match the card’s link specifications. Keep firmware and drivers up to date to ensure compatibility with virtualization platforms and storage stacks. Ensure adequate airflow in the server chassis and follow the server vendor’s guidelines for thermal and power management when populating multiple high-speed adapters.
