HPEP02054-B21

Synergy 6820C 25/50 Gb Converged Network Adapter (Internal Ethernet Card)

The HPEP02054-B21 Synergy 6820C Converged Network Adapteris a high-end internal mezzanine card built for HPEcomposable infrastructure. With dual 25 Gb or 50 Gb Ethernet ports, it delivers up to 50,000 Mbit/s bandwidth per port via PCIe Gen3 x16, optimizing performance for virtualized, storage, and compute-heavy workloads . This internal card uses unified networking and Fibre Channel over Ethernet (FCoE) techniques to reduce hardware count, simplify cabling, and improve efficiency. IT professionals implementing Synergy 480/660 Gen10 compute modules will benefit from higher VM density, lower CPU load, and streamlined network architecture. It supports advanced offload protocols, including SR-IOV, RoCE (v1/v2), iWARP, and tunneling (VXLAN, GENEVE, NVGRE), reducing latency and boosting throughput in demanding environments

Features

This internal mezzanine adapter integrates seamlessly into HPE Synergy compute modules, requiring no external cabling and enabling high-density deployment. It provides dual 25 Gb or 50 Gb Ethernet connectivity using PCIe 3.0 x16 interface for maximum throughput and energy-efficient operationIts converged architecture supports both Ethernet and Fibre Channel traffic over a single physical interface (CNA), accommodating unified LAN/SAN fabrics. The card offloads network and storage protocols via hardware acceleration to free up CPU cycles: SR-IOV for virtualization density, RDMA (RoCE v1/v2 and iWARP) for low-latency data flows, and VXLAN/Geneve/NVGRE for network virtualizationThe adapter supports core networking standards like IEEE 802.1Q/p/qaz/qbb/as and IEEE 1588 to ensure QoS, flow control, and precise timing for modern data center environments With a compact form factor and low thermal signature (≈14 W typical power draw), it fits into Synergy frames without sacrificing airflow or system reliabilityCoupled with HPEhigh-density 50 Gb Ethernet switches, this adapter enables scalable fabric architectures, cost reduction in compute modules and network elements, and improved overall operational efficiency.

Advanced Options

Engineered for enterprise-grade operation within HPESynergy systems, this adapter delivers high throughput under sustained workloads. Its use of PCIe Gen3 x16 maximizes data transfer efficiency while maintaining low latency. The hardware offload engines for RDMA and virtualization significantly reduce CPU utilization, allowing higher VM density and freeing server cycles for application workloads.Support for SR-IOV enables efficient VM networking by partitioning physical ports into virtual functions, enhancing virtualization performance. Protocol acceleration for VXLAN, NVGRE, and Geneve offloads ensures seamless overlay network operations in cloud and virtual environments. Compliance with IEEE 802.1 standards×including 802.1Qaz (DCBX), 802.1p, and IEEE 1588 PTP×guarantees network prioritization, congestion management, and clock synchronization mgmt
