As the number of cloud computing customers increases, ApsaraDB RDS aims to provide cost-effective database services based on existing storage resources. ApsaraDB RDS launches the general Enterprise SSD (ESSD) storage type that uses the next-generation storage architecture. This topic describes the concept, effective date, features, and pricing of the general ESSD storage type.
Introduction
A general ESSD is a new storage type supported by ApsaraDB RDS. General ESSDs support all features of ESSDs and the I/O burst feature. General ESSDs deliver high IOPS in scenarios in which the disk size remains unchanged, the disk size is small, and the disk I/O usage is high.
The following table describes the features of general ESSDs.
Effective date
June 20, 2024
Applicable scope
General ESSDs are supported for ApsaraDB RDS for MySQL instances.
NoteServerless RDS instances that run MySQL support only the I/O burst feature of general ESSDs.
General ESSDs are supported for ApsaraDB RDS for MySQL instances that use cloud disks.
Limits
The storage capacity of general ESSDs ranges from 10 GB to 64,000 GB.
You cannot change the storage type of your RDS instance from general ESSD to ESSD, but you can change the storage type from ESSD to general ESSD. For more information, see Change the storage type of an ApsaraDB RDS for MySQL instance from ESSD to general ESSD.
Billing rules
Billing methods
Fee for a general ESSD = Fee for the storage capacity that you purchase for your RDS instance + Fee for burstable I/O operations + Fee for I/O acceleration + Fee for the data archiving feature
For more information about the fees for each item, see the following topics:
Fee for the storage capacity that you purchase for your RDS instance
You are charged for the storage capacity that you purchase for your RDS instance. The subscription and pay-as-you-go billing methods are supported. The billing rules are the same as the billing rules for an ESSD of performance level 1 (PL1). For more information, see Billable items.
In the following regions, general ESSDs are more cost-effective than PL1 ESSDs regardless of the billing method, and the unit price of a general ESSD is lower than the unit price of a PL1 ESSD.
