Adaptive multipath fabric for balanced performance and high availability

A computing system providing high-availability access to computing resources comprising:

• a plurality of interfaces comprising a first interface and a second interface;
• a first switch:
• connected to the first interface via a first host link comprising a first end contacting the first switch and a second end contacting the first interface, and
• connected to at least one switch of a third switch or a fourth switch via a first cross-connection of a fabric comprising a first end contacting the first switch and a second end contacting the third switch or the fourth switch;
• a second switch:
• connected to the second interface via a second host link comprising a first end contacting the second switch and a second end contacting the second interface;
• and
• connected to at least one of the third switch or the fourth switch via a second cross-connection of the fabric comprising a first end contacting the second switch and a second end contacting the third switch or the fourth switch;
• a first set of computing resources comprising a first computing unit connected to:
• the first switch via a first resource connection of the fabric comprising a first end contacting the first switch and a second end contacting the first computing unit;
• and
• the second switch via a second resource connection of the fabric comprising a first end contacting the second switch and a second end contacting the first computing unit;
• and
• a second set of computing resources comprising a second computing unit connected to:
• the first switch via a third resource connection of the fabric comprising a first end contacting the first switch and a second end contacting the second computing unit;
• and
• the second switch via a fourth resource connection of the fabric comprising a first end contacting the second switch and a second end contacting the second computing unit,
• wherein the first host link supports a traffic bandwidth greater than or equal to a first total bandwidth required for the first set of computing resources to operate at full bandwidth,
• wherein the second host link supports a second traffic bandwidth greater than or equal to a second total bandwidth required for the second set of computing resources to operate at full bandwidth,
• wherein the first cross-connection supports at least a bandwidth based on the first total bandwidth and the number of interfaces, and
• wherein the second cross-connection supports at least a bandwidth based on the second total bandwidth and the number of interfaces.
