What kind of generator usually a supercomputer requires to ensure that it can continue to work if a power failure occurs?

Supercomputers typically require a high-capacity uninterruptible power supply (UPS) combined with backup generators to ensure continuous operation during power failures. These generators are usually diesel-powered and are designed to provide sufficient power to support the supercomputer's energy demands until the primary power source is restored. Additionally, redundancy in power systems is crucial to maintain operational integrity and prevent data loss.
