Rated Workload
Average annualized workload rating: <180 TB/year.
The AFR specification for the product assumes the I/O workload does not exceed
the average annualized workload rate limit of 180 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.
