Rated Workload

Average annualized workload rating: <300TB/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.
