Overview
The HPE P08421-B21 is a high-performance, dual-port 10GbE SFP+ network adapter designed for HPE ProLiant servers. This PCIe standup card addresses the need for high-throughput, low-latency network connectivity in demanding data center environments. It is engineered to support compute-intensive workloads such as server virtualization, high-performance computing, and server consolidation by providing a reliable and efficient I/O solution. This adapter leverages a Broadcom BCM57414 chipset to deliver its robust feature set. A key capability is its use of I/O offload technologies, including VXLAN and NVGRE tunnel offloads, which significantly reduce server CPU utilization by handling packet processing on the adapter itself. This frees up valuable processor cycles for critical applications, directly translating to improved overall system performance and efficiency within the host server. Engineered for seamless integration, the HPE P08421-B21 fits a standard PCIe 3.0 x8 slot in ProLiant rack servers. Its dual-port design provides an aggregate throughput of 20Gb, offering both high bandwidth and redundancy for mission-critical network links. The adapter supports Single Root I/O Virtualization (SR-IOV), which enhances virtual network performance while further decreasing CPU overhead in virtualized deployments.
