Mellanox ConnectX-5 100Gigabit Ethernet Card
ConnectX® -5 EN Adapter Card for Open Compute Project (OCP)
Single and dual-port 100GbE PCIe Gen4 intelligent RDMA-enabled network adapter card with advanced application offload and Multi-Host capabilities for Machine Learning, Web2.0, Cloud, and Storage platforms.
ConnectX-5 EN supports up to two ports of 100Gb Ethernet connectivity, sub-600ns latency, and very high message rate, plus PCIe Gen4 support and NVMe over Fabric offloads, providing the highest performance and most flexible solution for Open Compute Project servers and storage appliances while supporting the most demanding applications and markets: Machine Learning, Data Analytics, and more.
MACHINE LEARNING AND BIG DATA ENVIRONMENTS
Data analytics has become an essential function within many enterprise data centers, clouds and Hyperscale platforms. Machine learning relies on especially high throughput and low latency to train deep neural networks and to improve recognition and classification accuracy. As the first OCP card to deliver 200Gb/s throughput, ConnectX-5 dual-port 100GbE is the perfect solution to provide machine learning applications with the levels of performance and scalability that they require.
ConnectX-5 EN for Open Compute Project (OCP) utilizes RoCE (RDMA over Converged Ethernet) technology, delivering low-latency and high performance.
ConnectX-5 also supports GPUDirect® and Burst Buffer offload for background checkpointing without interfering in the main CPU operations, and the innovative transport service Dynamic Connected Transport (DCT) to ensure extreme scalability for compute and storage systems.
STORAGE ENVIRONMENTS
NVMe storage devices are gaining popularity, offering very fast storage access. The evolving NVMe over Fabric (NVMe-oF) protocol leverages the RDMA connectivity for remote access. ConnectX-5 offers further enhacements by providing NVMe-oF target offloads, enabling very efficient NVMe storage access with no CPU intervention, and thus improved performance and lower latency.
As with the earlier generations of ConnectX adapters, standard block and file access protocols can leverage RoCE for high-performance storage access. A consolidated compute and storage network achieves significant cost-performance advantages over multi-fabric networks.
ConnectX-5 enables an innovative storage rack design, Host Chaining, by which different servers can interconnect directly without involving the Top of the Rack (ToR) switch. Alternatively, the Multi-Host technology that was first introduced with ConnectX-4 can be used. Mellanox Multi-Host™ technology, when enabled, allows multiple hosts to be connected into a single adapter by separating the PCIe interface into multiple and independent interfaces. With the various new rack design alternatives, ConnectX-5 lowers the total cost of ownership (TCO) in the data center by reducing CAPEX (cables, NICs, and switch port expenses), and by reducing OPEX by cutting down on switch port management and overall power usage.
CLOUD AND WEB2.0 ENVIRONMENTS
Cloud and Web2.0 customers that are developing their platforms on Software Defined Network (SDN) environments, are leveraging their servers' Operating System Virtual-Switching capabilities to enable maximum flexibility.
