Overview The HPE P08421-B21 is a dual-port 10Gb Ethernet network adapter designed to enhance the connectivity of HPE ProLiant Gen10 servers. Equipped with two 10Gb SFP+ ports and powered by the Broadcom BCM57414 controller, it offloads packet processing from the CPU to maintain high performance for applications and virtualization. Its PCI Express 3.0 x8 interface ensures sufficient bandwidth for demanding data center environments. Key features Two 10Gb SFP+ ports provide fast and reliable network connections suitable for high-throughput workloads. Broadcom BCM57414 controller handles packet processing on the card, reducing CPU load and improving overall server efficiency. PCI Express 3.0 x8 interface delivers ample bandwidth to support continuous data flow without bottlenecks. Hardware offloads for VXLAN and NVGRE enhance performance in overlay network environments by minimizing latency. DPDK support enables developers to leverage hardware acceleration for increased I/O throughput in user-space applications. Optimized compatibility with HPE ProLiant Gen10 servers, including the DL380 Gen10, for seamless integration. Plug-in form factor allows quick installation into available PCIe slots, simplifying upgrades and maintenance. Wired connectivity ensures stable, low-latency links essential for virtualization hosts, clustered databases, and backup servers. Key specs Network ports: 2 x 10Gb SFP+ Controller: Broadcom BCM57414 Interface: PCI Express 3.0 x8 Offload support: VXLAN, NVGRE DPDK support: Yes Compatible servers: HPE ProLiant Gen10, including DL380 Gen10 Connectivity and compatibility This adapter fits into standard PCIe slots on HPE ProLiant Gen10 servers, providing two 10Gb SFP+ ports for fiber or direct attach copper connections.
