Product Overview

Single/Dual-Port Adapter Cards supporting 100Gb/s with Virtual Protocol Interconnect®

ConnectX®-4 adapter cards with Virtual Protocol Interconnect (VPI), supporting EDR 100Gb/s InfiniBandand 100Gb/s Ethernet connectivity, provide the highest performance and most flexible solution for highperformance, Web 2.0, Cloud, data analytics, database, and storage platforms. With the exponential growth of data being shared and stored by applications and social networks, theneed for high-speed and high performance compute and storage data centers is skyrocketing.ConnectX-4 provides exceptional high performance for the most demanding data centers, public andprivate clouds, Web2.0 and Big Data applications, as well as High-Performance Computing (HPC) andStorage systems, enabling today’s corporations to meet the demands of the data explosion. ConnectX-4 provides an unmatched combination of 100Gb/s bandwidth in a single port, the lowestavailable latency, and specific hardware offloads, addressing both today’s and the next generation’scompute and storage data center demands.

100Gb/s Virtual Protocol Interconnect (VPI) Adapter

ConnectX-4 offers the highest throughput VPI adapter, supporting EDR 100Gb/s InfiniBand and 100Gb/sEthernet and enabling any standard networking, clustering, or storage to operate seamlessly over anyconverged network leveraging a consolidated software stack.

I/O Virtualization

ConnectX-4 SR-IOV technology provides dedicated adapter resources and guaranteed isolation andprotection for virtual machines (VMs) within the server. I/O virtualization with ConnectX-4 gives datacenter administrators better server utilization while reducing cost, power, and cable complexity, allowing more Virtual Machines and more tenants on the same hardware.

HPC Environments

ConnectX-4 delivers high bandwidth, low latency, and high computation efficiency for the High Performance Computing clusters. Collective communication is a communication pattern in HPC in which all members of a group of processes participate and share data. CORE-Direct® (Collective Offload Resource Engine) provides advanced capabilities for implementing MPI and SHMEM collective operations. It enhances collective communication scalability and minimizes the CPU overhead for such operations, while providing asynchronous and high performance collective communication capabilities. It also enhances application scalability by reducing the exposure of the collective communication to the effects of system noise (the bad effect of systemactivity on running jobs). ConnectX-4 enhances the CORE-Direct capabilities by removing the restriction on the data length for which data reductions are supported.


ConnectX-4, utilizing IBTA RDMA (Remote Data Memory Access) andRoCE (RDMA over Converged Ethernet) technology, delivers low-latencyand high-performance over InfiniBand and Ethernet networks. Leveraging data center bridging (DCB) capabilities as well as ConnectX-4 advanced congestion control hardware mechanisms, RoCE provides efficient low-latency RDMA services over Layer 2 and Layer 3 networks.

Mellanox Peerdirect

PeerDirect communication provides high efficiency RDMA access byeliminating unnecessary internal data copies between componentson the PCIe bus (for example, from GPU to CPU), and therefore significantly reduces application run time. ConnectX-4 advanced acceleration technology enables higher cluster efficiency and scalability to tens of thousands of nodes.

Storage Acceleration

Storage applications will see improved performance with thehigher bandwidth EDR delivers. Moreover, standard block and fileaccess protocols can leverage RoCE and InfiniBand RDMA for high performance storage access. A consolidated compute and storage network achieves significant cost-performance advantages over multifabric networks.

Distributed RAID

ConnectX-4 delivers advanced Erasure Coding offloading capability,enabling distributed RAID (Redundant Array of Inexpensive Disks), a data storage technology that combines multiple disk drive components into a logical unit for the purposes of data redundancy and performance improvement. The ConnectX-4 family’s Reed-Solomoncapability introduces redundant block calculations, which, togetherwith RDMA, achieves high performance and reliable storage access.

Signature Handover

ConnectX-4 supports hardware checking of T10 Data Integrity Field /Protection Information (T10-DIF/PI), reducing the CPU overhead and accelerating delivery of data to the application. Signature handover ishandled by the adapter on ingress and/or egress packets, reducing the load on the CPU at the Initiator and/or Target machines.

Standard Host Management

Mellanox host management and control capabilities includeNC-SI over MCTP over SMBus, and MCTP over PCIe - Baseboard Management Controller (BMC) interface, as well as PLDM for Monitor and Control DSP0248 and PLDM for Firmware Update DSP0267.

Software Support

All Mellanox adapter cards are supported by Windows, Linuxdistributions, VMware, FreeBSD, and Citrix XENServer. ConnectX-4 VPI adapters support OpenFabrics-based RDMA protocols and softwareand are compatible with configuration and management tools from OEMs and operating system vendors.
