HP R0H67A Mellanox MCX4121A-ACAT EN 25GbE DP NICRU

Product Description

The HP R0H67A, also identified by its Mellanox chipset MCX4121A-ACAT, is a high-performance dual-port 25 Gigabit Ethernet (25GbE) network adapter designed for enterprise servers and demanding data center applications. This adapter leverages the capabilities of the Mellanox ConnectX-4 architecture, offering significant improvements in throughput, latency, and efficiency compared to previous generations. The 25GbE speed provides a substantial upgrade over 10GbE, enabling faster data transfers and supporting the growing demands of cloud computing, storage, and high-performance workloads. Featuring two SFP28 ports, the R0H67A allows for flexible connectivity using appropriate transceivers and fiber optic cables. SFP28 is the standard form factor for 25GbE, offering backward compatibility with SFP+ in some configurations. The adapter connects to the server via a high-speed PCIe interface, typically PCIe 3.0 or 4.0, ensuring that the network bandwidth does not become a bottleneck for data-intensive applications. It supports various Ethernet standards, including 25GBASE-SR for short-reach connections. This network adapter is equipped with advanced offload engines, such as RDMA (Remote Direct Memory Access) over Converged Ethernet (RoCE), which reduce CPU utilization and improve application performance by enabling direct memory access between network-connected systems. It is an ideal solution for storage networking, high-frequency trading, virtualization, and other applications where low latency and high bandwidth are critical. The dual-port design also supports link aggregation and failover, enhancing network reliability and performance.
