Redundant hardware

Redundant hardware definition

Redundant hardware means having extra backup equipment in a system or network to prevent problems and keep things running smoothly.

Redundant hardware examples:

  • Power Supplies: Having multiple power sources to keep devices powered up. If one power source fails, another takes over to prevent shutdown.
  • Storage: Making copies of important data on multiple storage devices. If one device fails, the duplicates ensure that the data is still available.
  • Network Components: Using backup network equipment like switches or routers. If one device stops working, another one takes over.
  • Servers or Systems: Using multiple servers that work together. If one server fails, the others handle the workload to keep everything running.
  • Cooling and Environmental Controls: This prevents overheating and keeps everything working properly.

Redundant hardware use cases:

  • Reliability: It makes systems more dependable by providing backups.
  • Fault Tolerance: It helps systems handle hardware failures without disruptions.
  • Continuous Operation: It that systems can keep operating even if there are issues.
  • Performance: It distributes workloads and prevents bottlenecks. It helps systems handle more tasks efficiently.
  • Disaster Recovery: It helps systems get back up and running quickly after disruptions.
  • Data Protection: If one storage device fails, the duplicate copies ensure that the data is still accessible and protected.
