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

A virtual switch traditionally resides in the hypervisor and switching is based on twelve-tuple matching on flows

Alternatively, the Multi-Host technology that was first introduced with ConnectX-4 can be used

As with the earlier generations of ConnectX adapters, standard block and file access protocols can leverage RoCE for high-performance storage access

ConnectX-5 enhances RDMA network capabilities by completing the Switch AdaptiveRouting capabilities and supporting data delivered out-of-order, while maintaining ordered completion semantics, providing multipath reliability and efficient support for all network topologies including DragonFly and DragonFly .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

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 EN utilizes RoCE RDMA over Converged Ethernet technology, delivering low-latency and high performance

ConnectX-5 offers further enhancements by providing NVMe-oF 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

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

Mellanox Multi-Host trade technology, when enabled, allows multiple hosts to be connected into a single adapter by separating the PCIe interface into multiple and independent interfaces

The evolving NVMe over Fabric NVMe-oF protocol leverages the RDMA connectivity for remote access

The virtual switch or virtual router software-based solution is CPU intensive, affecting system performance and preventing fully utilizing available bandwidth. /p

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 39 39 Operating System Virtual-Switching capabilities to enable maximum flexibility.Open V-Switch OVS is an example of a virtual switch that allows Virtual Machines
