MAINTENANCE
Five nines is a maintenance strategy, not an accident.
Data center maintenance shifts facility management from reactive firefighting to predictive orchestration. We work the four classical pillars — and align every visit to the SLA below.
04 PILLARS
The 4 pillars of maintenance
01
Preventive (PM)
Scheduled routines — cleaning, parts replacement, lubrication — driven by time intervals or manufacturer guidelines.
02
Predictive (PdM)
Real-time data from IoT sensors. Infrared thermography for hot spots; vibration analysis on chillers and pumps.
03
Corrective
Fixing equipment after a fault. Rapid-response kits and strict isolation procedures to protect live loads.
04
Evolutionary
Upgrading software, firmware and hardware infrastructure to improve energy efficiency and security posture.
SYSTEM BREAKDOWN
System priority matrix
What gets a 2-hour P1, what gets a 4-hour P2, and what waits for next business day.
| SYSTEM | P1 · CRITICAL · 2H | P2 · URGENT · 4H | P3 · STANDARD · NBD |
|---|---|---|---|
Electrical / UPS | Main breaker trip; UPS failing to take load during outage. | UPS on bypass; PDU failure in a redundant rack. | Burnt-out lighting; adding new circuits; display errors. |
Gensets | Generator won't start; ATS stuck in neutral. | Engine alarm (low coolant / battery); low fuel. | Block heater replacement; oil seepage; cosmetic repairs. |
Chillers / HVAC | Total loss of cooling (Temp > 85°F / 29°C). | Single chiller failure (N+1); pump failure (redundant active). | Office comfort cooling; filter changes; belt tightening. |
BMS / Controls | Total loss of monitoring; unable to command equipment. | Individual sensor failure; loss of remote access (local OK). | Software updates; reporting / logging errors; user access. |
Fuel Systems | Major fuel leak; pump failure preventing generator run. | Fuel polisher fault; day tank float switch alarm. | Tank gauge calibration; fuel sampling; minor rust repair. |
