Billing rule

Billing method

Performance (Locally Redundant) capacity

Billing is based on the peak storage usage per hour.

Billed storage = MAX(Accounted storage, Actual storage)
Actual storage is the total size of all files in the file system, excluding folders. This includes file holes.
Accounted storage is calculated by multiplying 5 MiB by the number of inodes for both files and folders. The number of inodes is available in the console and in capacity monitoring.

Pay-as-you-go: Storage fee = Billed storage (GiB) × Monthly unit price / 30 (days) / 24 (hours)

Provisioned throughput

Billing is based on the peak throughput usage per hour.

Billed throughput = Configured throughput - Baseline throughput.
Baseline throughput = MAX[Billed storage of the previous hour (GiB) × Baseline throughput per GiB (50 MiB/s)].
Configured throughput is the throughput configured for the current hour, in MiB/s.

Pay-as-you-go: Storage fee = Throughput (MiB/s) × Monthly unit price / 30 (days) / 24 (hours)
