Rated workload
Average annualized workload rating: <55 TB/year.
The AFR specification for the product assumes the I/O workload does not exceed the aver-
age annualized workload rate limit of 55 TB/year. Workloads exceeding the annualized rate
may degrade the product AFR and impact reliability as experienced by the particular appli-
cation. The average annualized workload rate limit is in units of TB per calendar year.
