With the exponential increase in usage of data and the creation of new applications, the demand for the highest throughput, lowest latency, virtualization and sophisticated data acceleration engines continues to rise. ConnectX-4 Lx EN enables data centers to leverage the world's leading interconnect adapter for increasing their operational efficiency, improving server utilization, maximizing applications productivity, while reducing total cost of ownership (TCO).
ConnectX-4 Lx EN adapter cards provide a combination of 1, 10, 25, 40, and 50 GbE bandwidth, sub-microsecond latency and a 75 million packets per second message rate. They include native hardware support for RDMA over Converged Ethernet (RoCE), Ethernet stateless offload engines, Overlay Networks, GPUDirect technology and Multi-Host technology.
• 1/10/25/40/50 Gb/s speeds
• Single and dual-port options
• Virtualization
• Low latency RDMA over Converged Ethernet (RoCE)
• Multi-Host technology connects up to 4 independent hosts
• CPU offloading of transport operations
• Application offloading
• PeerDirect communication acceleration
• Hardware offloads for NVGRE, VXLAN and GENEVE encapsulated traffic
• End-to-end QoS and congestion control
• Hardware-based I/O virtualization
• RoHS compliant
• ODCC compatible
• Various form factors available
Storage Acceleration
Storage applications will see improved performance with the higher bandwidth ConnectX-4 Lx EN delivers. Moreover, 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.
Host Management
Mellanox host management and control capabilities include NC-SI over MCTP over SMBus, and MCTP over PCIe - Baseboard Management Controller (BMC) interface, as well as PLDM for Monitoring and Control DSP0248 and PLDM for Firmware Update DSP0267.
I/O Virtualization
ConnectX-4 Lx EN SR-IOV technology provides dedicated adapter resources and guaranteed isolation and protection for virtual machines (VMs) within the server. I/O virtualization with ConnectX-4 Lx EN gives data center administrators better server utilization while reducing cost, power, and cable complexity, allowing more virtual machines and more tenants on the same hardware.
Mellanox PeerDirect®
Mellanox PeerDirect communication provides high efficiency RDMA access by eliminating unnecessary internal data copies between components on the PCIe bus (for example, from GPU to CPU), and therefore significantly reduces application run time. ConnectX-4 Lx EN advanced acceleration technology enables higher cluster efficiency and scalability to tens of thousands of nodes.
Software Support
All Mellanox adapter cards are supported by Windows, Linux distributions, VMware, FreeBSD, and Citrix XENServer. ConnectX-4 Lx EN supports various management interfaces and has a rich set of tools for configuration and management across operating systems.
Additionally, ConnectX-4 Lx EN provides the option for a secure firmware update check using digital signatures to prevent remote attackers from uploading malicious firmware images; this ensures that only officially authentic images produced by Mellanox can be installed, regardless whether the source of the installation is the host, the network, or a BMC.
Wide Selection of Ethernet Adapter Cards
ConnectX-4 Lx EN adapter cards offer a cost-effective Ethernet adapter solution for 1, 10, 25, 40 and 50 Gb/s Ethernet speeds, enabling seamless networking, clustering, or storage. The adapter reduces application runtime, and offers the flexibility and scalability to make infrastructure run as efficiently and productively as possible.
ConnectX-4 Lx Ethernet adapter cards are available in several form factors including: low-profile stand-up PCIe, OCP 2.0 Type 1, OCP 2.0 Type 2, and OCP 3.0 small form factor
Overlay Networks
In order to better scale their networks, data center operators often create overlay networks that carry traffic from individual virtual machines over logical tunnels in encapsulated formats such as NVGRE and VXLAN. While this solves network scalability issues, it hides the TCP packet from the hardware offloading engines, placing higher loads on the host CPU. ConnectX-4 Lx EN effectively addresses this by providing advanced NVGRE, VXLAN and GENEVE hardware offloading engines that encapsulate and de-capsulate the overlay protocol headers, enabling the traditional offloads to be performed on the encapsulated traffic for these and other tunneling protocols (GENEVE, MPLS, QinQ, and so on). With ConnectX-4 Lx EN, data center operators can achieve native performance in the new network architecture.
RDMA over Converged Ethernet (RoCE)
ConnectX-4 Lx EN supports RoCE specifications delivering low-latency and high- performance over Ethernet networks. Leveraging data center bridging (DCB) capabilities as well as ConnectX-4 Lx EN advanced congestion control hardware mechanisms, RoCE provides efficient low-latency RDMA services over Layer 2 and Layer 3 networks.
Innovative Mellanox Multi-Host technology enables data centers to design and build scale-out heterogeneous compute and storage racks, with direct connectivity between compute elements and the network. Significantly improving cost savings, flexibility, and total cost of ownership, Mellanox MultiHost technology provides better power and performance, while achieving maximum data processing and data transfer at minimum capital and operational expenses.
Mellanox Multi-Host works by allowing multiple hosts to connect into a single interconnect adapter, by separating the adapter PCIe interface into several independent PCIe interfaces. Each interface connects to a separate host CPU—with no performance degradation. Reducing data center CAPEX and OPEX, Mellanox Multi-Host slashes switch port management and power usage by reducing the number of cables, NICs and switch ports required by four independent servers, from four to one of each. Additional features & benefits of Mellanox Multi-Host technology:
• Enables IT managers to remotely control the configuration and power state of each host individually; guaranteeing host security and isolation, the management of one host does not affect host traffic performance nor the management of other hosts.
• Lowering total cost of ownership (TCO), Mellanox Multi-Host uses a single BMC, with independent NC-SI/MCTP management channels for each of the managed hosts.
• Mellanox Multi-Host also supports a heterogeneous data center architecture; the various hosts connected to the single adapter can be x86, Power, GPU, Arm or FPGA, thereby removing any limitations in passing data or communicating between compute elements.
