System and method for supporting heterogeneous and asymmetric dual rail fabric configurations in a high performance computing environment

A method for supporting redundant independent networks in a high performance computing environment, comprising:

• providing, at a computer, the computer comprising one or more microprocessors,
• a plurality of hosts;
• wherein a host of the plurality of hosts is connected, by a first host port, to a private network fabric,
• wherein the host is further connected, via a second host port, to a public cloud network, and
• wherein the private network fabric and the public cloud network each respectively comprise an independent rail;
• wherein a workload is provisioned at a host of the plurality of hosts, the host of the plurality of hosts being respectively connected to each independent rail via a different port of a plurality of ports associated with the host;
• wherein the workload is assigned to one of the private network fabric and the public cloud network.

A non-transitory computer readable storage medium comprising instructions for supporting redundant independent networks in a high performance computing environment, comprising:

• providing, at the computer, the computer comprising one or more microprocessors,
• a plurality of hosts;
• wherein a host of the plurality of hosts is connected, by a first host port, to a private network fabric, wherein the host is further connected, via a second host port, to a public cloud network, and wherein the private network fabric and the public cloud network each respectively comprise an independent rail;
• wherein a workload is provisioned at a host of the plurality of hosts, the host of the plurality of hosts being respectively connected to each independent rail via a different port of a plurality of ports associated with the host;
• wherein the workload is assigned to one of the private network fabric and the public cloud network.
