HP 851226-B21 OPA Mezzanine 100Gb 1P Adapter

Product Description

The HP 851226-B21 is a specialized network adapter designed for high-density, high-performance computing environments. As an Optical Passive Adapter (OPA) Mezzanine card, it leverages optical technology to achieve extremely high data transfer rates of 100 Gigabits per second (Gbps). The 'passive' nature suggests it relies on the server's chassis for cooling and power, simplifying its design and potentially reducing power consumption. This adapter features a single port (1P), typically utilizing a QSFP28 connector, which is the standard for 100Gbps optical transceivers. Its mezzanine form factor allows it to be integrated directly onto the server's motherboard or a dedicated mezzanine slot, providing a compact and efficient solution for network connectivity. It is engineered to meet the demanding bandwidth requirements of modern data centers, high-performance computing (HPC) clusters, and large-scale enterprise networks. The primary purpose of the 851226-B21 is to facilitate ultra-fast interconnectivity between servers or between servers and high-speed network fabrics. Its low latency and high throughput make it ideal for applications such as large-scale data analysis, distributed computing, storage networking, and AI/ML workloads where rapid data movement is critical. Compatibility is typically limited to specific HP server generations and models that support this type of mezzanine adapter.
