A storage resource package is a prepaid resource type launched by TDSQL-C for MySQL. It can be used to deduct the storage resources used by Serverless instances. The resource packages will not affect the pay-as-you-go billing mode of Serverless storage resources. After a resource package is used, settlement is performed per hour by deducting the actual usage from your purchased resource package. In this way, you can benefit from the preferential storage resource prices while enjoying the high-precision billing mode of Serverless. This document describes the specification types and prices of storage resource packages.

Case
We will compare the storage resource fees of two instances (one without a storage resource package and the other with a storage resource package) to more intuitively understand the cost difference between using and not using a storage resource package.
Case background
Region: Beijing.
Instance Mode: Single-Node Edition.
The first instance: Unused storage resource package will be billed on a pay-as-you-go basis, denoted as Instance A.
The second instance: Utilizing the storage resource package, a Basic Edition storage resource package was purchased and bound, offering a storage capacity of 10TB with a validity period of 6 months. Denoted as Instance B.
Operation scenario: Instance A and instance B have been running continuously for 3 hours respectively. The storage space used in the first hour is 0.5TB, the storage space used in the second hour is 1TB, and the storage space used in the third hour is 2TB. The storage resource costs of these 3 hours are calculated and compared below.
Cost comparison
|
Billing formula | storage space fees = storage space price × storage space total storage resource fees of running for 3 hours = fees for the first hour + fees for the second hour + fees for the third hour | storage space fees = storage space price × storage space total storage resource fees of running for 3 hours = fees for the first hour + fees for the second hour + fees for the third hour |
Billing model | pay as you go | storage resource pack |
Storage space fees (unit price) | 0.00072 USD per GB Approximately equal to 0.72 USD per TB | 0.2568 USD per TB |
Storage space | the storage space used in the first hour: 0.5TB the storage space used in the second hour: 1TB the storage space used in the third hour: 2TB | the storage space used in the first hour: 0.5TB the storage space used in the second hour: 1TB the storage space used in the third hour: 2TB |
Storage resource fees | 0.72 x 0.5 + 0.72 x 1 + 0.72 x 2 = 2.52 USD | 0.2568 x 0.5 + 0.2568 x 1 + 0.2568 x 2 = 0.8988 USD |
Subsequent billing | subsequent operations of instance A will continue to use pay-as-you-go billing, resulting in new fees | the total storage resource package purchased by instance B is 10TB. In the past 3 hours, 3.5TB has been consumed, and the remaining amount is 6.5TB. This storage resource package will continue to be consumed in the future. Instance B will not be restored until the storage resource package is consumed or expires. For pay-as-you-go billing, you can also continue to purchase and bind other storage resource packages before the storage resource package is consumed. |
Compare results
It can be seen from the above comparison that since the unit price of storage space in a storage resource package is lower than that of pay-as-you-go, the overall storage resource fees is reduced, and it is more favorable to use a storage resource package. The unit prices of storage resource packages for Basic Edition, General Edition, and Enterprise Edition are different. You can choose the appropriate specification type based on the actual storage required.
Note
Storage resource packages will accumulate the actual storage usage on an hourly basis for deduction, which is more cost-effective and flexible than the pay-as-you-go option. Before the deduction of the serverless cluster, you must first bind a storage resource pack. The cluster will not be terminated when the resource pack is unbound, used up, or expires. It will instead be billed on a pay-as-you-go basis. It is important to note the following points:
Storage resource packs are classified into two types: those for the Chinese mainland and those for regions outside the Chinese mainland. Each type is specified to be shared by all serverless clusters in the region, that is, one storage resource pack can be shared by multiple serverless clusters.
A serverless cluster can be bound to a maximum of ten storage resource packages, with support for adjusting the consumption priority order of multiple storage resource packages. The cluster will consume resources in ascending order based on the priority level numbers. Storage resource packages will accumulate the consumption on an hourly basis for deduction.
Storage resource packages do not support downgrade once purchased.
Management
Refund
For resource packages that remain unused within their validity period, each Tencent Cloud account (primary account) is calculated on a calendar year basis, with a maximum of 20 refundable resource packages per year. As for resource packages that have expired or been fully utilized, refunds are currently not supported. For detailed refund instructions, see Requesting Refund for Resource Pack. Note：
Regarding the limitation on the number of refunds, the system calculates this on a calendar year basis. The first calendar year cycle is from June 30, 2023, at 23:59:59 to July 1, 2024, at 00:00:00. The count refreshes on July 1 at 00:00:00 every year, thus the second calendar year cycle is from July 1, 2024, at 00:00:00 to June 30, 2025, at 23:59:59, and so on.
