Product Overview

High Performance & Flexibility

ConnectX-3 Pro adapter cards with 10/40/56 Gigabit Ethernet connectivity with hardware offload engines to Overlay Networks (“Tunneling”), provide the highest performing and most flexible interconnect solution for PCI Express Gen3 servers used in public and private clouds, enterprise data centers, and high performance computing. Public and private cloud clustered databases, parallel processing, transactional services, and high-performance embedded I/O applications will achieve significant performance improvements resulting in reduced completion time and lower cost per operation.

Virtualisation Overlay Networks

Infrastructure as a Service (IaaS) cloud demands that data centers host and serve multiple tenants, each with their own isolated network domain over a shared network infrastructure. To achieve maximum efficiency, data centre operators are creating overlay networks that carry traffic from individual Virtual Machines (VMs) in encapsulated formats such as NVGRE and VXLAN over a logical “tunnel,” thereby decoupling the workload’s location from its network address. Overlay Network architecture introduces an additional layer of packet processing at the hypervisor level, adding and removing protocol headers for the encapsulated traffic. The new encapsulation prevents many of the traditional “offloading” capabilities (e.g. checksum, TSO) from being performed at the NIC.ConnectX-3 Pro effectively addresses the increasing demand for an overlay network, enabling superior performance by introducing advanced NVGRE and VXLAN hardware offload engines that enable the traditional offloads to be performed on the encapsulated traffic. With ConnectX-3 Pro, data center operators can decouple the overlay network layer from the physical NIC performance, thus achieving native performance in the new network architecture.

I/O Virtualisation

ConnectX-3 Pro SR-IOV technology provides dedicated adapter resources and guaranteed isolation and protection for virtual machines (VMs) within the server. I/O virtualisation with ConnectX-3 Pro gives data centre managers better server utilisation while reducing cost, power, and cable complexity.

RDMA over Converged Ethernet

ConnectX-3 Pro utilising IBTA RoCE technology delivers similar low-latency and high-performance over Ethernet networks. Leveraging Data Center Bridging capabilities, RoCE provides efficient low latency RDMA services over Layer 2 Ethernet. With link-level interoperability in existing Ethernet infrastructure, Network Administrators can leverage existing data centre fabric management solutions.

Sockets Acceleration

Applications utilising TCP/UDP/IP transport can achieve industry-leading throughput over 10/40/56GbE. The hardware-based stateless offload engines in ConnectX-3 Pro reduce the CPU overhead of IP packet transport. Socket acceleration software further increases performance for latency sensitive applications.

Storage Acceleration

A consolidated compute and storage network achieves significant cost-performance advantages over multi-fabric networks. Standard block and file access protocols can leverage Ethernet or RDMA for high-performance storage access. All Mellanox adapter cards are supported by Windows, Linux distributions, VMware, FreeBSD, Ubuntu, and Citrix XenServer. ConnectX-3 Pro adapters support OpenFabrics-based RDMA protocols and software and are compatible with configuration and management tools from OEMs and operating system vendors.
