2.13Reliability

2.13.1Annualized Failure Rate (AFR) and Mean Time Between Failures (MTBF)

The product shall achieve an Annualized Failure Rate (AFR) of 1.1% (MTBF of 800 thousand hours) when operated at 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 the product reliability.

•A workload rate below the average annualized specified limits. Operation at excessive I/O duty cycle may degrade product reliability.

The enterprise application nearline environment of power-on-hours, temperature, and I/O duty cycle affect the product AFR and MTBF.

Annualized Failure Rate (AFR)

1.1% (nominal power, 40°C case temperature)

 

 

Load unload cycles

300,000 cycles

 

 

Rated Workload

Average rate of <180TB/year

 

The MTBF specification for the drive assumes the I/O workload does not exceed the Average

 

Annualized Workload Rate Limit of <180TB/year. Workloads exceeding the annualized rate may

 

degrade the drive MTBF and impact product reliability. The Average Annualized Workload Rate Limit

 

is in units of TB per year, or TB per 8760 power on hours.

 

Workload Rate = TB transferred x ( 8760 / recorded power on hours).

Preventive maintenance

None required.

 

 

2.14Agency certification

2.14.1Safety certification

These products are certified to meet the requirements of UL60950-1, CSA60950-1 and EN60950 and so marked as to the certify agency.

2.14.2Electromagnetic compatibility

Hard drives that display the CE mark comply with the European Union (EU) requirements specified in the Electromagnetic Compatibility Directive (2004/108/EC) as put into place 20 July 2007. Testing is performed to the levels specified by the product standards for Information Technology Equipment (ITE). Emission levels are defined by EN 55022, Class B and the immunity levels are defined by EN 55024.

Drives are tested in representative end-user systems. Although CE-marked Seagate drives comply with the directives when used in the test systems, we cannot guarantee that all systems will comply with the directives. The drive is designed for operation inside a properly designed enclosure, with properly shielded I/O cable (if necessary) and terminators on all unused I/ O ports. Computer manufacturers and system integrators should confirm EMC compliance and provide CE marking for their products.
