Maintenance Strategies
Types of Maintenance
Preventive Maintenance
Regularly scheduled maintenance activities designed to prevent equipment failures before they occur.
- Scheduled inspections & servicing
- Parts replacement based on time/usage
- Cleaning & calibration
- Lubrication & adjustments
- Software updates & patches
Predictive Maintenance
Condition-based maintenance using real-time monitoring and data analysis to predict failures.
- IoT sensors & monitoring
- Thermal imaging & analysis
- Vibration analysis
- Power quality monitoring
- Machine learning predictions
Proactive Maintenance
Root-cause analysis and system improvements to eliminate the source of potential failures.
- Root cause analysis
- Design improvements
- Process optimization
- Redundancy planning
- Continuous improvement
Maintenance Schedule
Recommended maintenance frequencies for different data center components based on industry best practices.
| Component | Activity | Frequency | Criticality | Estimated Time | Tools Required |
|---|---|---|---|---|---|
| UPS System | Battery testing & replacement | Quarterly | Critical | 2-4 hours | Battery tester, multimeter |
| Cooling System | Filter cleaning/replacement | Monthly | High | 1-2 hours | Vacuum, pressure gauge |
| Generator | Load bank testing | Yearly | Critical | 4-8 hours | Load bank, fuel test kit |
| Fire Suppression | System inspection & testing | Quarterly | Critical | 2-3 hours | Pressure gauges, test equipment |
| Network Equipment | Firmware updates | Quarterly | High | 1-3 hours | Console cable, TFTP server |
| Server Hardware | Health checks & cleaning | Monthly | Medium | 1-2 hours | Compressed air, diagnostics |
| Physical Security | Access control testing | Monthly | High | 1-2 hours | Access cards, test logs |
| Cabling Infrastructure | Visual inspection & testing | Yearly | Medium | 4-8 hours | Cable tester, label maker |
