Rated Workload
Average annualized workload rating: 300 TB/year.
The AFR specification for the product assumes the I/O workload does not exceed the average
annualized workload rate limit of 300 TB/year. Workloads exceeding the annualized rate may
degrade the product AFR and impact reliability as experienced by the particular application. The
average annualized workload rate limit is in units of TB per calendar year.
