Storage plan offset factors
Storage plans have different offset factors for different regions. Therefore, the deductible capacity of a resource plan also varies based on the region of the instance. For example, for a 100 GB storage plan, the following table shows the storage resource capacity that can be offset per hour during its validity period.

Examples
Deductible amount of a resource plan = Actual storage usage of the instance × Offset factor of the instance's region.
For example, assume you purchase a 100 GB storage plan and have a single-zone Enterprise instance in Singapore, a single-zone Enterprise instance in the US, and a multi-zone Enterprise instance in Hangzhou. The storage resource consumption of these instances can be offset by the same storage plan. If the Singapore instance uses 12 GB of storage resources for 1 hour, this offsets 12 GB × 1 H × 1.00 = 12 GB·h from the storage plan. If the US instance uses 10 GB of storage resources for 1 hour, this offsets 10 GB × 1 H × 0.94 = 9.4 GB·h from the storage plan. If the Hangzhou instance uses 16 GB of storage resources for 1 hour, this offsets 16 GB × 1 H × 1.34 = 21.44 GB·h from the storage plan. At the end of the hour, the total offset amount is 12 GB·h + 9.4 GB·h + 21.44 GB·h = 42.84 GB·h. Because the total offset amount is within the capacity of the purchased storage plan, no extra fees are incurred.
Purchase storage plans
Storage plans do not support refunds. Before you purchase a storage plan, estimate your resource usage to avoid waste. Storage usage that exceeds the capacity of the storage plan is billed on a pay-as-you-go basis.
