Interconnecting global virtual planes

One or more computer readable non-transitory media storing computer-executable instructions that, when executed by one or more processors, cause:

• in a network environment comprising a plurality of host machines that are communicatively coupled to each other via a network fabric comprising a plurality of switches, the plurality of switches comprising a plurality of ports, each host machine in the plurality of host machines comprising one or more GPUs, associating a first subset of ports from the plurality of ports with a first virtual plane, the first virtual plane identifying a first collection of resources to be exclusively used for communicating packets from and to host machines associated with the first virtual plane;
• associating a second subset of ports from the plurality of ports with a second virtual plane that is different from the first virtual plane;
• associating a first host machine to the first virtual plane and a second host machine to the second virtual plane;
• and
• for a packet originating at a first GPU on the first host machine and destined for a second GPU on the second host machine, communicating the packet from the first GPU on the first host machine to the second GPU on the second host machine, using ports from the first subset of ports and the second subset of ports.

A computing device comprising:

• one or more processors;
• and
• a memory including instructions that, when executed with the one or more processors, cause the computing device to, at least:
• in a network environment comprising a plurality of host machines that are communicatively coupled to each other via a network fabric comprising a plurality of switches, the plurality of switches comprising a plurality of ports, each host machine in the plurality of host machines comprising one or more GPUs, associate a first subset of ports from the plurality of ports with a first virtual plane, the first virtual plane identifying a first collection of resources to be exclusively used for communicating packets from and to host machines associated with the first virtual plane;
• associate a second subset of ports from the plurality of ports with a second virtual plane that is different from the first virtual plane;
• associate a first host machine to the first virtual plane and a second host machine to the second virtual plane;
• and
• for a packet originating at a first GPU on the first host machine and destined for a second GPU on the second host machine, communicate the packet from the first GPU on the first host machine to the second GPU on the second host machine, using ports from the first subset of ports and the second subset of ports.
