This is a Mellanox ConnectX-4 VPI Single-Port Host Channel Adapter (HCA) (P/N: MCX455A-FCAT). This high-performance adapter is engineered to provide an extremely powerful and flexible interconnect solution for High-Performance Computing (HPC), enterprise data centers, and storage infrastructure. Its key feature is Virtual Protocol Interconnect (VPI), which allows the card to operate as either an EDR 100Gb/s InfiniBand port or a 100Gb/s Ethernet port, offering unparalleled flexibility and a clear upgrade path.
Key Features
-
Virtual Protocol Interconnect (VPI): The single QSFP28 port can be configured to run either EDR 100Gb/s InfiniBand for the lowest latency or 100Gb/s Ethernet for broad data center compatibility, providing a versatile, future-proof solution.
-
100Gb/s Throughput: Delivers a massive 100Gb/s of bandwidth, making it ideal for the most data-intensive applications.
-
Advanced Offloads: Supports advanced offload engines, including RDMA (Remote Direct Memory Access) over InfiniBand and Ethernet (RoCE), to reduce CPU overhead and significantly improve system efficiency.
-
PCIe 3.0 x16 Interface: Utilizes a full PCIe 3.0 x16 host interface to provide the maximum possible bandwidth between the server and the network fabric.
