18 CONSTELLATION ES.2 SERIAL ATA PRODUCT MANUAL, REV. H
2.12 ELECTROMAGNETIC IMMUNITY
When properly installed in a representative host system, the drive operates without errors or degradation in performance when subjected
to the radio frequency (RF) environments defined in the following table:
2.13 RELIABILITY
2.13.1 Annualized Failure Rate (AFR) and Mean Time Between Failures (MTBF)
The product shall achieve an Annualized Failure Rate (AFR) of 0.73% (MTBF of 1.2 million hours) when operated nominal power and
typical case temperatures of 40°C. Operation at temperatures outside the specifications in Section 2.9 may increase the product AFR
(decrease MTBF). AFR and MTBF are population statistics that are not relevant to individual units.
AFR and MTBF specifications are based on the following assumptions for business critical storage system environments:
• 8760 power-on-hours per year.
• Operations at nominal voltages.
• Temperatures outside the specifications in Section 2.9 may reduce thee product reliability.
• Normal I/O duty cycle for enterprise nearline applications. Operation at excessive I/O duty cycle may degrade product reli-
ability.
The enterprise application nearline environment of power-on-hours, temperature, and I/O duty cycle affect the product AFR and MTBF.
2.14 AGENCY CERTIFICATION
2.14.1 Safety certification
