HPE Ethernet 10Gb 2-port SFP+ BCM57414 Adapter

The HPE P08421-B21 is a dual-port network adapter that gives your ProLiant Gen10 server two 10Gb SFP+ links without weighing down the CPU. Built on the Broadcom BCM57414 controller, it performs much of the packet processing on the card itself, so the processor can stay focused on applications and virtualization workloads.

A PCI Express 3.0 x8 interface feeds each port with enough bandwidth to keep data moving quickly in high-demand environments. When your infrastructure relies on overlay networks, the adapter’s offload support for VXLAN and NVGRE helps maintain low latency and stable performance. Developers who use DPDK can tap into its hardware acceleration to push I/O throughput even further.

The card slots neatly into HPE ProLiant servers such as the DL380 Gen10, making it a practical upgrade for data centers that are outgrowing 1Gb connections. It is a good fit for virtualization hosts, clustered databases, and backup servers that need consistent 10Gb throughput without adding CPU overhead.

Installation is straightforward: insert the adapter, connect your SFP+ optics or cables, and configure networking in the operating system. Once online, you gain the bandwidth needed for fast east-west traffic, storage replication, and time-sensitive applications.
