HPEP16818-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 HPEProLiant 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.
