Product Description
The Mellanox MCX515A-GCAT is a cutting-edge 100 Gigabit Ethernet Network Interface Card (NIC) built on the advanced ConnectX-5 EN architecture. Designed for the most demanding data center and high-performance computing (HPC) environments, this card offers a single QSFP28 port capable of delivering blazing-fast 100Gbps connectivity. It utilizes the high-bandwidth PCIe 3.0 x16 interface, ensuring that the network throughput is not bottlenecked by the host system's bus. This NIC is engineered for low latency and high throughput, making it ideal for applications such as artificial intelligence (AI), machine learning (ML), big data analytics, high-frequency trading, and large-scale storage solutions. It supports advanced features like RDMA over Converged Ethernet (RoCE) v2, which allows for efficient data transfer between servers with reduced CPU overhead. Additionally, it includes support for NVMe over Fabrics (NVMe-oF) for high-performance storage access and Data Plane Development Kit (DPDK) for optimized packet processing. The MCX515A-GCAT also incorporates technologies like Single Root I/O Virtualization (SR-IOV) to enhance virtual machine performance and isolation. Its robust feature set and high-speed capabilities make it a critical component for modern cloud infrastructure, hyperscale data centers, and research institutions requiring maximum network performance and efficiency. The QSFP28 form factor allows for flexible cabling options, including direct attach copper (DAC) or optical transceivers, depending on the required distance and infrastructure.
