OCP 3.0 mezzanine form factor — this HPE Marvell QL41132HQCIJ adapter delivers enterprise-grade 10 Gigabit Ethernet connectivity within the compact, modular footprint required by HPE ProLiant Gen10 and Gen10 Plus server architectures. The P28778-B21 integrates directly into the OCP Mezzanine 3.0 slot, eliminating the need for dedicated PCIe card slots while maintaining full performance and manageability. Backed by the Marvell FastLinQ QL41132HQCIJ controller, this genuine HPE OEM solution provides 2 SFP+ ports running at 10GbE speeds, supported by PCIe 3.0 x8 connectivity via the OCP3 mezzanine connector.
Network engineers and infrastructure teams deploying HPE ProLiant environments will find robust offload capabilities including TSO, LRO, RSS, VLAN tag insertion and stripping, and checksum offload — reducing CPU overhead and improving throughput across virtualized and bare-metal workloads. SR-IOV virtualization support enables secure multi-tenancy and flexible resource allocation. Full integration with HPE iLO, HPE Smart Update Manager (SUM), and Service Pack for ProLiant (SPP) simplifies provisioning and lifecycle management. The adapter meets CE, FCC, and RoHS regulatory standards, and is validated across Windows Server, Red Hat Enterprise Linux, SUSE Linux Enterprise Server, and VMware ESXi operating systems.
