Provides high-performance and flexible solutions with up to two ports of 100GbE connectivity and 750ns latency. Delivers a range of innovative accelerations, such as Signature Handover (T10-DIF) in hardware, an embedded PCIe Switch, and NVMe over Fabric target offloads. ConnectX-5 adapter cards also bring advanced Open vSwitch offloads to Telecommunications and cloud data centers to drive extremely high packet rates and throughput with reduced CPU resource consumption, thus boosting data center infrastructure efficiency. ConnectX-5 cards also offer advanced Mellanox Multi-Host® and Mellanox Socket Direct® technologies.
- Overlay Networks (e.g., VXLAN, NVGRE, MPLS, GENEVE, and NSH) header encapsulation & decapsulation.
- Stateless offloads of inner packets and packet headers' re-write, enabling NAT functionality and more.
- Flexible and programmable parser and match-action tables, which enable hardware offloads for future protocols.
- SR-IOV technology, providing dedicated adapter resources, guaranteed isolation and protection for virtual machines (VMs) within the server.
- Network Function Virtualization (NFV), enabling a VM to be used as a virtual appliance. The full datapath operation offloads, hairpin hardware capability, and service chaining enable data to be handled by the virtual appliance with minimum CPU utilization.
Mellanox ASAP2 - Accelerated Switching and Packet Processing® technology enable offloading the vSwitch/vRouter by handling the data plane in the NIC hardware without modifying the control plane. This results in significantly higher vSwitch/vRouter performance without the associated CPU load. Additionally, intelligent ConnectX-5's flexible pipeline capabilities, including the flexible parser and flexible match-action tables, are programmable, enabling hardware offloads for future protocols.
The embedded PCIe switch enables customers to build standalone storage or Machine Learning appliances. As with earlier generations of ConnectX adapters, standard block and file access protocols 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, which enables different servers to interconnect without involving the Top of the Rack (ToR) switch. Leveraging Host Chaining, ConnectX-5 lowers the data center's total cost of ownership (TCO) by reducing CAPEX (cables, NICs, and switch port expenses). OPEX is also reduced by cutting down on switch port management and overall power usage.
Host Management
Host Management includes NC-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
