Optical inter-switch link cluster

A computing system comprising:

• a plurality of server computing devices;
• and
• an optical inter-switch link (ISL) cluster including a plurality of switch chips, each of the switch chips being connected to one or more of the server computing devices at least partially through an optical cable, the optical ISL cluster comprising:
• an array of first switch trays arranged in a first orientation, each of the first switch trays including a plurality of first switch chips disposed therein and connected to each other through optical cables thereon;
• a plurality of first optical connectors connected to the plurality of first switch chips;
• an array of second switch trays arranged in a second orientation different from the first connection, each of the second switch trays including a plurality of second switch chips disposed thereon and connected to each other through optical cables thereon;
• a plurality of second optical connectors connected to the plurality of second switch chip;
• a first shuffle tray arranged along the array of first switch trays, the first shuffle tray including a plurality of optical cables configured to connect each of the plurality of second switch chips on a first part of the second switch trays to all of the plurality of second switch chips on a second part of the second switch trays;
• and
• a second shuffle tray arranged along the array of second switch trays, the second shuffle tray including a plurality of optical cables configured to connected each of the plurality of first switch chips on a first part of the first switch trays to all of the plurality of first switch chips on a second part of the first switch tray;
• each of the plurality of first optical connectors connected to each of the first switch trays being connected to one of the plurality of second optical connectors of a different one of the plurality of second switch trays.

A method for establishing all-to-all connections among a plurality of switch, the method comprising:

• establishing optical connections between each of a first part of the plurality of switches disposed in an array of first switch trays arranged in a first orientation and all of a second part of the plurality of switches disposed in an array of second switch trays arranged in a second orientation different from the first orientation;
• establishing optical connections between each of a first subpart of the second part of the switches and all of a second subpart of the second part of the switches using a first shuffle tray arranged along the array of first switch trays, the first shuffle tray including a plurality of optical cables configured to connect each of the plurality of second switch chips on a first part of the second switch trays to all of the plurality of second switch chips on a second part of the second switch trays;
• establishing optical connections between each of a first subpart of the first part of the switches ad all of a second subpart of the first part of the switches using a second shuffle tray arranged along the array of second switch trays, the second shuffle tray including a plurality of optical cables configured to connect each of the plurality of first switch chips on a first part of the first switch trays to all of the plurality of first switch chips on a second part of the first switch trays;
• establishing optical connections among switches in each of the first switch trays through optical cables disposed in each of the first switch trays;
• and
• establishing optical connections among switches in each of the second switch trays through optical cables disposed in each of the second switch trays.
