Episode 19 — Redundant Power — UPS Systems, Circuits, and Providers
This episode explains the role of redundant power systems in maintaining server availability during outages or electrical faults. We cover uninterruptible power supplies (UPS) in detail, including online, line-interactive, and standby designs, and how they protect against voltage drops, surges, and complete loss of power. The discussion extends to using multiple power circuits, separate utility providers, and redundant power supply units within servers to ensure continuous operation.
We then examine real-world deployment strategies, such as configuring UPS units to support graceful shutdowns, balancing load across dual power feeds, and scheduling battery maintenance to avoid failures during emergencies. These principles are directly relevant to both exam scenarios and operational planning, where reliable power systems are critical to service continuity.
