Schneider Galaxy VX UPS

A UPS at this scale is not backup power in the sense a home generator is; it is a bridge of seconds, long enough for a diesel generator to spin up or for a controlled shutdown to save checkpoints before the building goes dark. Modularity is the operative feature: capacity adds in blocks as the facility grows, and a failed module is replaced without derating the rest. Nothing on this site names which UPS sits under any specific system, because vendors rarely disclose it and it is not the kind of fact anyone thinks to publish, which is itself a useful observation about how thoroughly the facility layer stays invisible next to the compute it supports.
