The Omni-Path Host Fabric in Supermicro Super I/O Module

High Performance Computing (HPC) solutions require the highest levels of performance, scalability, and availability to power complex application workloads. Designed specifically for HPC, the AOC-MHFI-i1C, uses an advanced "on-load" design that automatically scales fabric performance with rising server core counts, making these adapters ideal for today’s increasingly demanding workloads. Available in SIOM form factor and operates at 100Gbps throughput. The AOC-MHFI-i1C is the most compact and powerful networking adapter in the market today.

This product is only available through Supermicro.
