Episode 133: Hardware Redundancy — Routers, Switches, and Facility Infrastructure
20 Jul 2025
Hardware failures are inevitable—but outages are not, if redundancy is properly built into your network. In this episode, we focus on how to create fault-tolerant infrastructure through redundant routers, switches, and physical links. We explore concepts like dual-homing, redundant power supplies, cooling backups, and battery-based UPS systems. You’ll also learn how to assess single points of failure and plan for seamless failover during maintenance or emergencies.Beyond networking gear, we examine facility-level concerns such as redundant HVAC, generators, and structured cabling. These physical layers of resilience are often overlooked until disaster strikes. Whether you’re supporting a branch office or a full data center, this episode teaches you to think like a systems engineer—prioritizing uptime through proactive design.
