HPE Mellanox MCX512F-ACHT Ethernet 10/25Gb 2-Port SFP28 Adapter with High Profile Bracket. P/N: P16004-001.

This is a genuine HPE Mellanox MCX512F-ACHT Ethernet 10/25Gb 2-Port SFP28 Adapter with High Profile Bracket (HPE P/N: P13186-001, P13188-B21, P16004-001; Mellanox P/N: MCX512F-ACHT; PCB P/N: PCB001996_00). Engineered to accelerate server performance and optimize data center efficiency, this adapter provides dual-port connectivity for both 10 Gigabit Ethernet (10GbE) and 25 Gigabit Ethernet (25GbE) networks. Utilizing the SFP28 form factor, it offers flexible connectivity for fiber optic or direct attach copper (DAC) cables. The ConnectX-5 (often the base for this model) technology delivers industry-leading low latency, high bandwidth, and advanced features such as RoCE (RDMA over Converged Ethernet) and SR-IOV, making it ideal for high-performance computing (HPC), cloud data centers, enterprise servers, and virtualized environments where maximizing network throughput and minimizing CPU overhead are critical.

Key Features 

• Genuine HPE / Mellanox Adapter: Ensures full compatibility, validated performance, and seamless integration with HPE ProLiant servers and other compatible systems.

• Dual-Port 10/25GbE Connectivity: Provides flexible, high-speed networking with support for both 10 Gigabit and 25 Gigabit Ethernet speeds per port.

• SFP28 Form Factor: Offers versatile connectivity via SFP28 transceivers (for fiber) or Direct Attach Copper (DAC) cables (transceivers/cables not included).

• PCIe Gen3/Gen4 x8 Interface: Utilizes a high-bandwidth PCIe interface (typically Gen3 or Gen4, depending on the exact variant and host system) to ensure maximum data throughput to the server.

• Mellanox ConnectX-5 Technology (Implied): Leveraging Mellanox's advanced architecture for ultra-low latency, high throughput, and efficient hardware offloads.

• RoCE (RDMA over Converged Ethernet) Support: Enables direct memory access between servers, bypassing CPU overhead, which is critical for HPC and storage applications.

• SR-IOV (Single-Root I/O Virtualization): Enhances virtualization efficiency by allowing virtual machines to directly access network hardware resources, reducing latency and improving VM density.

• High Profile Bracket: Designed for installation in standard full-height server and workstation chassis.

• Advanced Offloads: Supports various hardware offloads (e.g., stateless offloads, overlay networks) to free up CPU cycles and boost application performance.
