(T10-DIF) in hardware, an embedded PCIe Switch, and NVMe over Fabric target offloads. MCX515A-CCAT also brings advanced Open vSwitch offloads to telecommunications and cloud data centers to drive extremely high packet rates and throughput with reduced CPU resource consumption, thus boosting data center infrastructure efficiency.

This ConnectX-5 Ethernet Adapter is available for PCIe Gen 3.0 servers and provides support for 1, 10, 25, 40, 50 and 100 GbE speeds in stand-up PCIe cards. MCX515A-CCAT also offers advanced Mellanox Multi-Host® and Mellanox Socket Direct® technologies.

Key Features of ConnectX-5 Ethernet Adapter MCX515A-CCAT

Optimized RoCE for High-Performance Networking

Network-intensive applications like networked storage or cluster computing need a network infrastructure with a high bandwidth and low latency. RDMA over Converged Ethernet (RoCE) uses advanced Ethernet networking and offloads to reduce latency for applications requiring higher throughput and faster response times.

A key technology advancement in GPU-GPU communications has been GPUDirect RDMA, which feeds data directly to GPU memory without needing to make buffer copies or interrupt the host. ConnectX-5 Ethernet Adapter MCX515A-CCAT makes it easier to deploy GPUDirect over RoCE by enabling a direct RDMA path for data exchange between the GPU and other servers or storage.

As with earlier generations of ConnectX adapters, standard block and file access protocols leverage RoCE for high-performance storage access. A consolidated compute and storage network achieves significant cost-performance advantages over multi-fabric networks.

Advanced SDN and Virtualization

Virtualization is essential for cloud data centers, offering agility, flexibility, and scalability. However, traditional software-based virtualization consumes CPU resources, impacting performance and efficiency.

The MCX515A-CCAT integrates ASAP2 (Accelerated Switch and Packet Processing) technology, offloading vSwitch/vRouter functions to hardware for significantly higher performance compared to software-based solutions. This reduces CPU load while enhancing SDN, NFV, and next-generation firewall performance.

Supporting SR-IOV, MCX515A-CCAT delivers industry-leading DPDK performance, improving management, and troubleshooting on servers. It also features advanced on-chip networking for seamless VM and container communication, optimizing private and hybrid cloud deployments.

Best-in-Class Storage Offloads

With AI, big data and real-time analysis workloads, faster connections are necessary not just between servers but also to storage. Beyond just a faster connection speed, MCX515A-CCAT adds a layer of innovation to enable more scalable, resilient and easy-to-deploy storage solutions. This includes acceleration and offloads for NVMe drives, NVMe over Fabric (NVMe-oF) and RDMA technology, plus optional Data Integrity Factor (T10-DIF) offloads and storage encryption for both data at rest and data in motion.

For storage workloads, MCX515A-CCAT delivers a range of innovative accelerations, such as Signature Handover (T10-DIF) in hardware, an embedded PCIe Switch, and NVMe over Fabric target offloads. MCX515A-CCAT also brings advanced Open vSwitch offloads to telecommunications and cloud data centers to drive extremely high packet rates and throughput with reduced CPU resource consumption, thus boosting data center infrastructure efficiency.
