ConnectX-4 Lx EN 25GbE Mellanox Network Card Dual Port SFP28 PCIe3.0 X8 MCX4121A-ACAT

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.
