HPE P16818-B21

534M FlexFabric Dual‑Port 10 GbE Gigabit Ethernet Adapter (Refurbished)

The HPE P16818‑B21 (534M FlexFabric Adapter) delivers dual-port 10 GbE connectivity in a mezzanine form factor tailored forBladeSystem c-Class Gen8/Gen9 servers. Integrating advanced networking and storage offload capabilities on a single chip, this adapter provides converged Ethernet and storage protocol support (iSCSI, FCoE). Its integrated NPAR and SR‑IOV virtualization enhancements offer efficient bandwidth segmentation and reduced CPU load, making it ideal for blade deployments with Virtual Connect Flex‑10 modules in virtualized or converged data center scenarios.

Features

This Type‑A mezzanine card connects directly into Type A/B mezzanine slots of HPE ProLiant BL460c and BL660c blades (Gen8/Gen9), delivering two independent 10 GbE ports via Broadcom/Cavium 57810S silicon. Each port supports full-duplex throughput of 20 Gb/s (40 Gb/s total), enabling high-performance traffic across virtualized environments. FlexFabric technology enables each port to be partitioned into up to four physical NICs with bandwidth allocation in 100 Mb increments when used alongside Flex‑10 modules. Advanced features such as tunnel offload (VXLAN/NVGRE), NPAR, SR‑IOV, iSCSI/FCoE offload, DPDK, and Precision Time Protocol (PTP IEEE 1588) make it ideal for converged, virtual, and software-defined infrastructure deployments

Advanced Options

This adapter delivers enterprise-grade, line-rate performance with minimal CPU overhead thanks to deep packet offloading and virtualization support. Jumbo frame support (up to 9 KB) and QoS (802.1p) improve throughput and traffic prioritization.

Product Key Features

    • 2 × 10 GbE ports (full-duplex, 20 Gb/s each; 40 Gb/s aggregate)

    • Cavium/Broadcom 57810S FlexFabric chipset

    • Mezzanine Type A form factor for HPE blade servers

    • Flex‑10/NPAR support (up to 4 FlexNICs per port)

    • Offload capabilities: iSCSI, FCoE, VXLAN/NVGRE, DPDK, SR‑IOV

    • Virtualization-ready: SR‑IOV, NetQueue, Microsoft VMQ

Reliability & Performance

The built-in Sea of Sensors 3D enhances thermal management, optimizing fan speeds only where required to reduce energy consumption. Support for IEEE 1588 Precision Time Protocol allows for sub-microsecond clock synchronization—critical in time-sensitive applications. As a refurbished unit, each adapter is fully tested and backed by a 90‑day warranty; new units receive up to 1‑year limited coverage via server warranty.

Key Features :

    • Dual 10 GbE ports (20 Gb/s per port)

    • Cavium/Broadcom 57810S chipset

    • FlexibleLOM mezzanine card (Type A/B slot)

    • Flex‑10/NPAR virtualization: up to 4 NICs per port

    • Offloads: iSCSI, FCoE, VXLAN, NVGRE, DPDK, QoS

    • SR‑IOV, jumbo frames, RSS, PXE boot, VLAN support
