HPE P28787-B21 10Gb Dual-Port SFP+ Network Adapter
Overview
The HPE P28787-B21 is a 10 Gigabit Ethernet network adapter built on PCIe Gen3x8 architecture—designed for surveillance integrators, data center architects, and system integrators who need to move high-bandwidth video streams or dense camera metadata across enterprise networks without bottlenecking at the adapter level. The stand-up form factor and dual SFP+ ports (10 Gb per port, 20 Gb aggregate throughput) make this card a straightforward drop-in upgrade for existing server infrastructure running multi-camera recording clusters, large-scale NVR farms, or IP security appliances that demand deterministic, low-latency network I/O.
The P28787-B21 (often searched as P28787 B21) sits at the intersection of cost-effective 10 Gb networking and proven enterprise reliability—no exotic licensing, no proprietary drivers beyond standard Linux/Windows kernel support, and a footprint compact enough to coexist in mixed-purpose server racks without special thermal or mechanical accommodation.
Key Features
- Dual 10 Gb SFP+ ports: Two independent 10 Gb data paths in a single card—meaning you can dedicate one port to inbound camera feeds (from a management switch) and a second to NVR storage egress, or configure active-active bonding for 20 Gb total throughput. Real benefit: no single-port bottleneck when recording dozens of 4K or high-bitrate streams simultaneously.
- PCIe Gen3x8 bus interface: An x8 link (versus x4) delivers roughly 8 Gb/s of host-to-card throughput in each direction—ample for sustained 10 Gb line rates on both ports without host CPU thrashing. If your surveillance server also runs VMS software, database queries, or other I/O-heavy workloads, the Gen3x8 architecture keeps network I/O from starving compute or storage traffic.
- Stand-up form factor: The vertical orientation fits standard full-height PCIe slots in 1U, 2U, and larger server chassis without requiring extender cables or special riser board workarounds. Simplifies integration in dense NVR appliances or surveillance-grade servers where every slot counts and cable runs are space-constrained.
- SFP+ optical/copper flexibility: SFP+ receptacles accept both 10GbE copper (DAC, direct-attach copper cables up to ~7 m) and optical transceivers (LC single-mode or multimode). Real deployment win: run copper between adjacent switches in a machine room; go optical across longer distances or noisy environments (parking lot camera arrays feeding back to a central datacenter) without changing the card.
- Enterprise driver and firmware support: HPE maintains driver packages for RHEL, CentOS, Windows Server, and ESXi—no dependency on hobbyist or unsupported third-party firmware. For surveillance integrators who standardize on Milestone Xprotect, Genetec Security Center, or proprietary NVR OSes, the P28787-B21 integrates without custom kernel patches or risk of driver incompatibility during OS updates.
- No-frills power profile: The card draws power exclusively from the PCIe slot itself (max ~25W)—no auxiliary 6-pin or 8-pin power connector needed. In surveillance deployments where redundant power supplies and PDU management are already complex, eliminating extra wiring reduces installation time and troubleshooting surface area.
Integration and Compatibility
The P28787-B21 integrates into any x8 or x16 PCIe Gen3 slot (Gen4/Gen5 slots are backward-compatible). Standard Linux drivers expose the adapter as two discrete 10 Gb interfaces (ethX/ethY naming), which operate independently or bond via LACP, bonding, or OS-level failover logic. Windows Server and ESXi recognize it as a standard network device—no special VMS driver required, just standard network stack configuration.
For surveillance-specific workflows: pair the P28787-B21 with a managed 10 Gb switch (Arista, Mellanox, or brand-neutral) and fan out to conventional PoE or non-PoE 1 Gb camera switches via 10-to-1 oversubscription. The dual-port architecture allows you to isolate management traffic (NVR to VMS software, analyst to UI) on one port and dedicate the second to camera-to-NVR video ingress—a clean logical split that simplifies QoS policy and troubleshooting when something does go wrong.
Deployment Considerations
The P28787-B21 is a passive adapter—it performs no packet inspection, encryption, or video optimization. It is purely a transport pipe. If you need network segmentation, firewalling, or traffic shaping, those functions belong upstream in your managed switches or firewall appliances, not on this card.
Power consumption and heat: the card itself is well-behaved (passive heatsink, no active fans), but ensure your server chassis has adequate PCIe cooling (typically a standard extractor fan exhausts through the rear I/O bezel). In surveillance server specs, confirm that the target platform (Dell PowerEdge, HPE ProLiant, Lenovo ThinkSystem) lists the P28787-B21 or equivalent 10 Gb cards in its supported hardware list—most modern platforms do, but air-gapped or hardened builds sometimes restrict NIC choices.

Frequently Asked Questions
Q: Does the P28787-B21 support SFP+ optical transceivers, or only copper DACs?
A: Both. The SFP+ form-factor receptacles accept either 10GbE copper direct-attach cables (up to ~7 meters) or optical transceivers (single-mode, multimode, or wavelength-agnostic). This flexibility lets you mix copper for short runs in the machine room and optical for longer-distance camera backhauls to a central NVR facility.
Q: What operating systems and hypervisors support the P28787-B21?
A: HPE provides drivers for RHEL, CentOS, Windows Server, and ESXi. The card is recognized as a standard 10 Gb Ethernet adapter by the kernel—no proprietary VMS or surveillance-specific drivers are required. Standard network stack configuration (IP assignment, bonding, VLAN tagging) applies.
Q: Can I use the P28787-B21 to split one 10 Gb connection into two independent 5 Gb links?
A: No. Each SFP+ port operates independently at 10 Gb full-duplex. You cannot configure them for lower rates or aggregate them into a single virtual interface without external switch support. Both ports run at line rate or not at all.
Q: Does the P28787-B21 require a separate power connector?
A: No. Power is drawn entirely from the PCIe slot (max ~25W). No auxiliary 6-pin or 8-pin power connector is needed, which simplifies installation in power-constrained appliances.
Q: Is the P28787-B21 NDAA Section 889 compliant?
A: No compliance claim is documented in the available evidence. If NDAA compliance is a requirement, contact HPE directly or consult your organization's procurement policy regarding embedded network adapters.
Q: What PCIe slot types and generations does the P28787-B21 support?
A: The card is built for PCIe Gen3 x8 slots. It will also work in x16 or higher slots (backward-compatible), but requires at least PCIe Gen3 to avoid performance degradation. Gen4 and Gen5 systems are backward-compatible; Gen2 systems may negotiate at reduced speeds.
The HPE P28787-B21 is a workhorse 10 Gb adapter for surveillance data center builds where you're consolidating 24/7 camera feeds into central NVR appliances or Milestone/Genetec server clusters. The dual SFP+ ports and PCIe Gen3x8 bus deliver the throughput you need to avoid I/O saturation when recording dozens of high-bitrate streams—a real problem in medium-to-large deployments where a single 1 Gb NIC bottlenecks everything.
Technical Highlights:
- Dual 10 Gb SFP+ ports: 20 Gb aggregate throughput means you can partition camera ingress (one port) from NVR storage or management egress (second port) without performance contention. PCIe Gen3x8 backplane ensures the server-to-card path doesn't become the bottleneck.
- SFP+ optical/copper agility: Run copper DACs (direct-attach cables) for machine-room adjacency, optical for remote camera farms—no hardware redesign, just swap transceivers. This matters when your NVR facility is across a parking lot or in a separate building.
- PCIe slot-based power: Zero external power connectors required (max ~25W from the slot itself). In surveillance appliances where PDU real estate is already maxed out, this is a genuine operational win.
Deployment Considerations:
- The P28787-B21 is a pure transport adapter—no packet inspection, no encryption offload, no video optimization. Network security (segmentation, firewalling, QoS) lives upstream in managed switches, not on this card.
- Confirm your target NVR server platform (Dell PowerEdge, HPE ProLiant, Lenovo ThinkSystem) lists 10 Gb NIC support in the hardware compatibility guide. Most modern platforms do, but air-gapped or hardened surveillance appliances sometimes restrict NIC choice to pre-approved models.
Deploy the P28787-B21 in central NVR farms where you're aggregating camera feeds from distributed switches and need to split inbound video traffic from management/storage egress without latency or loss. It's not for small, single-switch surveillance networks—a couple of 1 Gb NICs will do fine there. But once you're running 30+ cameras into one appliance, this adapter earns its cost back in eliminated troubleshooting and network redesign.
