HPE P10106-B21 Intel E810 Dual-Port 10/25GbE OCP3 Network Adapter
Overview
The P10106-B21 is an HPE-branded Intel E810 network adapter delivering dual-port 10/25GbE connectivity via SFP28 in the OCP3 (Open Compute Project 3.0) mezzanine form factor. Designed for HPE HPE server accessories and targeted at Gen10 Plus platforms, it slots into the dedicated OCP3 bay rather than consuming a standard PCIe slot — freeing expansion slots for storage controllers, GPUs, or additional networking cards in network adapter deployments. The dual SFP28 ports support both 10GbE and 25GbE operation, so the same card works in environments transitioning from 10G leaf switches to 25G spine-and-leaf fabrics without a hardware swap. For video surveillance infrastructure, this adapter suits high-density NVR servers and video management workloads where aggregate camera stream throughput exceeds what a single 10GbE port can sustain — 25GbE per port gives headroom for multi-stream 4K or high-frame-rate deployments across large camera counts.
Compatibility
The P10106-B21 is designed for HPE ProLiant Gen10 Plus servers equipped with an OCP3 mezzanine slot. Compatible platforms include the ProLiant DL360 Gen10 Plus, DL380 Gen10 Plus, DL560 Gen10 Plus, and ML350 Gen10 Plus, as well as Apollo and Synergy Gen10 Plus nodes with OCP3 support. The OCP3 form factor is not backward-compatible with OCP2 bays — verify your server's mezzanine specification before ordering. SFP28 ports accept DAC cables, AOC cables, and SFP28 optical transceivers operating at either 10GbE or 25GbE; the port auto-negotiates to the connected switch speed. Switch infrastructure must support 25GbE SFP28 ports for full-speed operation.
Installation Notes
Installation requires powering down the server and inserting the card into the OCP3 bay on the system board — no tools beyond a standard server maintenance kit are needed for most Gen10 Plus chassis. HPE recommends installing the latest system ROM and network driver package (Intel E810 series driver) via HPE SPP (Service Pack for ProLiant) after seating the adapter to ensure full firmware compatibility and iLO visibility. For PoE switch and NVR infrastructure planning, pair this adapter with 25GbE-capable top-of-rack switches to avoid speed negotiation fallback to 10GbE.
