HPE P05891-B21 40GbE 2-Port QSFP+ Network Adapter
Overview
The HPE P05891-B21 is a high-performance, dual-port 40GbE PCI Express network adapter designed for HPE ProLiant servers in demanding data center and enterprise environments. It directly addresses I/O bottlenecks by providing a significant upgrade in network bandwidth, making it an ideal solution for environments running data-intensive applications, high-performance computing clusters, or large-scale virtualization deployments. This adapter leverages 40GBASE-X technology and QSFP+ connectors to deliver an aggregate bidirectional throughput of up to 160 Gbps. The enhanced data rate dramatically reduces latency and improves server efficiency for workloads such as database access, storage networking, and live virtual machine migrations. This ensures critical applications have the high-speed connectivity required to meet performance targets and service-level agreements. Designed as a standard PCIe plug-in card, the adapter integrates seamlessly into rack-mount servers. Its physical placement within the server chassis allows for a direct, high-speed connection to the system’s data bus. Management of the device is typically handled through the server’s integrated management platform, ensuring a unified and consistent administrative experience within the existing infrastructure.
