HPE 789003-B21 10GbE SFP+ Dual Port Network Adapter
Overview
The HPE 789003-B21 is a dual-port 10GbE network adapter designed to enhance server I/O performance and alleviate network bottlenecks in demanding enterprise environments. Engineered for HPE ProLiant Gen9 rack servers, this adapter provides the high-throughput, low-latency connectivity required for modern data centers. It is an ideal solution for optimizing cloud efficiency, high-performance computing clusters, and virtualization-dense deployments where data access speed is critical. At its core, this adapter utilizes a PCIe 3.0 x8 host interface to deliver up to 40 Gb/s of aggregate bi-directional throughput. This substantial bandwidth is essential for applications dependent on high-speed block storage access and database performance. It supports advanced stateless offload technologies for VXLAN and NVGRE, which preserves CPU resources for application processing, directly improving server efficiency and virtual machine density. Physically, the adapter is a low-profile card that ships with both half-height and full-height brackets, ensuring compatibility across a range of server chassis. Management is integrated within the HPE ecosystem, allowing for configuration and monitoring through tools like HPE Systems Insight Manager (SIM). This simplifies administration by providing a unified management interface for both servers and networking hardware, ensuring consistent performance and reliability.
