HPE P21109-B21 10/25Gb 2-Port SFP28 Network Adapter
Overview
The HPE P21109-B21 is a high-throughput, dual-port 10/25GbE network adapter designed for demanding data center environments. As a critical component for HPE ProLiant Gen10 Plus and Gen11 servers, this adapter addresses the need for scalable, low-latency connectivity required by hybrid cloud services, data analytics, and high-performance computing workloads. It provides a direct and efficient path for moving large volumes of data between the server and the network fabric. This adapter leverages a PCI Express 3.0 x8 host interface to ensure there is ample bandwidth to support its dual 25GbE ports running at line rate. A key operational benefit comes from its support for I/O offloads, including RDMA and Tunneling, which significantly reduces the server’s CPU utilization. By handling network traffic processing on the card itself, it frees up processor cycles for critical applications, directly improving server efficiency and overall system performance. Engineered as a plug-in card, the adapter installs into a standard PCIe slot within compatible HPE servers, integrating seamlessly into the existing infrastructure. This ensures a reliable and validated solution for connecting servers to top-of-rack switches. For enhanced security, the adapter features a root of trust architecture that authenticates firmware updates. This process ensures that only signed and trusted firmware is installed, protecting the server and network from rogue firmware installations.
