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