Overview
Specs
Reviews
- ConnectX-5 supports two ports of 10/25 GB/s SFP28 Ethernet connectivity, while delivering low sub-600ns latency, extremely high message rates, PCIe switch and NVMe over Fabric offloads. ConnectX-5 providing the highest performance and most flexible solution for the most demanding applications and markets: Machine Learning, Data Analytics, and more.
HPC ENVIRONMENTS
ConnectX-5 delivers high bandwidth, low latency, and high computation efficiency for high performance,data intensive and scalable compute and storage platforms. ConnectX-5 offers enhancements to HPC infrastructures by providing MPI and SHMEM/PGAS and Rendezvous Tag Matching offload, hardware support for out-of-order RDMA Write and Read operations, as well as additional Network Atomic and PCIe Atomic operations support.
ConnectX-5 also supports 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 (NVMf) protocol leverages the RDMA connectivity for remote access. ConnectX-5 offers further enhancements by providing NVMf target offloads, enabling very efficient NVMe storage access with no CPU intervention, and thus improved performance and lower latency.
Moreover, the embedded PCIe switch enables customers to build standalone storage or Machine Learning appliances. 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.
Open V-Switch (OVS) is an example of a virtual switch that allows Virtual Machines to communicate with each other and with the outside world. A virtual switch traditionally resides in the hypervisor and switching is based on twelve-tuple matching on flows. The virtual switch or virtual router software-based solution is CPU intensive, affecting system performance and preventing fully utilizing available bandwidth.
