MTBF and Serviceability
| Attribution | Failures | MTBF | UDT | Serviceability |
| Cray | 3 | 244 | 04:52:00 | 99.3% |
| Site | 0 | ∞ | 00:00:00 | 100% |
| External | 0 | ∞ | 00:00:00 | 100% |
| Other | 0 | ∞ | 00:00:00 | 100% |
| Overall | 3 | 244 | 04:52:00 | 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.
