HPE P06251-H21 Ethernet 100Gb 2-port Network Adapter

The HPE P06251-H21 is a high-performance network adapter engineered to accelerate data-intensive workloads within modern data center environments. Designed for deployment in HPE ProLiant DL and Apollo Gen10 and Gen10 Plus servers, this versatile adapter provides critical low-latency, high-bandwidth connectivity for demanding High-Performance Computing (HPC) and enterprise applications. It effectively addresses the challenges of data bottlenecks, ensuring rapid data transfer and communication essential for distributed computing and storage solutions. This adapter leverages the robust PCIe 3.0 x16 interface, delivering up to 100Gbps throughput across its two QSFP56 ports. At its core, the adapter incorporates the MCX653106A-ECAT controller, based on advanced Mellanox ConnectX-6 technology, which includes multiple offloading engines. These mechanisms significantly reduce CPU overhead by handling tasks like MPI tag matching, rendezvous offloads, and adaptive routing, thereby freeing up server processing power for core application tasks and boosting overall system efficiency. With its standup low-profile (LP) form factor, the adapter integrates seamlessly into a wide range of server configurations, providing flexibility in rack-mounted and specialized HPC systems. Optimized for server and storage clustering, it plays a pivotal role in creating scalable and responsive network fabrics. The P06251-H21 is compatible with both Direct Attach Copper (DAC) and Active Optical Cables (AOC), offering diverse cabling options to suit various deployment distances and requirements within the data center.
