Mellanox Multi-Host is designed to provide flexibility and savings in building next-generation, scalable Cloud, Web 2.0 and high-performance data centers. The technology enables designing and building new scale-out heterogeneous compute and storage racks with direct connectivity between compute elements, storage elements and the network, better power and performance management, while achieving maximum data processing and data transfer at minimum capital and operational expenses. It is available in ConnectX-4 10/25/50/100 Gigabit Ethernet adapters, and in OCP-based boards as part of Facebook’s recently announced Yosemite platform. The technology enables direct connectivity of multiple hosts to a single network controller, while keeping each host completely independent from the others. Moreover, the hosts can be based on different CPU architecture and dedicated Quality of Service and host management channels are guaranteed to each of the hosts. At the same time, the hosts share the same network interface. The direct connectivity between the multiple hosts and the centralized network controller enables direct data access with lowest latency, overcoming performance bottlenecks due to the current server NUMA architecture. Furthermore, it enables better utilization of lower performance CPUs which can share network aggregation directly from the network controller.
