MTBF and Serviceability
Attribution | Failures | MTBF | UDT | Serviceability |
Cray | 3 | 244 | 05:14:00 | 99.3% |
Site | 0 | ∞ | 00:00:00 | 100% |
External | 0 | ∞ | 00:00:00 | 100% |
Other | 0 | ∞ | 00:00:00 | 100% |
Overall | 3 | 244 | 05:14:00 | 99.3% |
- Note 1: Serviceability%= 100*(WCT-SDT-UDT)/(WCT-SDT)
- Note 2: MTBF (Mean Time Between Failures) is defined as 732/Number of failures.
