Chips are merely "computing units". To organize them into scalable AI clusters, it is necessary to complete the collaborative design of three major components: rack/cabinet-level system integration, data center-level high-speed networking, and high-density power distribution and cooling. The boundaries between these three are rapidly blurring: server manufacturers no longer focus solely on individual machines but are moving towards full-chain integration from racks to cabinets, rows, and entire server rooms; networking solutions are no longer just "pathways" but must be coupled with scheduling, storage, and job orchestration; cooling is no longer an "auxiliary facility" but a hard constraint on power consumption/thermal density limits and per-unit data center output...
