HPE 789002-B21 Ethernet 10Gb 2-port 546SFP+ Adapter
Overview
The HPE 789002-B21 is a dual-port 10 Gigabit Ethernet server adapter, designed to provide high-throughput, low-latency network connectivity for HPE ProLiant servers. Housed in a plug-in card form factor, it is engineered for demanding data center environments, virtualization workloads, and high-performance computing clusters. This adapter addresses critical needs for increased bandwidth by aggregating two 10GbE ports, effectively preventing network I/O bottlenecks in enterprise applications. At its core, the adapter enhances server efficiency by offloading network protocol processing from the CPU. It supports advanced features such as TCP/IP checksum offload, SR-IOV, and VMQ, which are vital for improving performance in virtualized environments. These capabilities allow data to be moved more efficiently, freeing up CPU cycles for application processing and increasing virtual machine density and performance. Designed for seamless integration into HPE ProLiant Gen9 servers, the 789002-B21 fits into a PCIe 3.0 x8 slot. Management is integrated within the HPE ecosystem, allowing administrators to configure and monitor the adapter through existing server management tools. Its dual SFP+ cage design offers flexibility, supporting both fiber optic and direct attach copper (DAC) cabling for various network infrastructure requirements.
