Product Description
The HPE P24838-B21 is a high-performance dual-port 25 Gigabit Ethernet (25GbE) network adapter designed to deliver exceptional speed and efficiency for demanding server workloads. Each of the two SFP28 ports supports data rates up to 25Gb/s, providing substantial bandwidth for applications such as high-performance computing (HPC), big data analytics, storage networking, and cloud infrastructure. This adapter is engineered to reduce latency and increase throughput, thereby enhancing overall system performance. This adapter is built to support advanced networking technologies, including RDMA (Remote Direct Memory Access) and RoCE (RDMA over Converged Ethernet). These features enable direct memory access between servers, bypassing the CPU and operating system, which significantly lowers latency and improves efficiency. This makes the P24838-B21 an excellent choice for latency-sensitive applications and high-speed storage solutions. Featuring a PCIe Gen3 x8 interface, the adapter ensures high-speed communication with the host system, preventing network bottlenecks. The dual-port design offers flexibility for network redundancy, load balancing, or connecting to multiple network segments. The SFP28 interface allows for the use of various optical transceivers, providing adaptability to different network distances and infrastructure requirements. The HPE P24838-B21 is a robust solution for organizations seeking to upgrade their network infrastructure to meet the evolving demands of modern data centers.
