change point
In order to better serve customers, the ECS team has adjusted the minimum capacity limit of the system disk
- linux system
- The core os is adjusted to start at 30G
- The remaining linux system capacity is adjusted to start at 20G
- The freebsd system is adjusted to start at 20G
- The windows system still maintains the 40G start
Applicable scene
- Currently, the new system disk limit is only applicable to newly purchased ECS instances, and existing instances with a system disk larger than 20G cannot be changed to the new minimum capacity.
- Suitable for users who do not have strong requirements for the size of the system disk
The current elastic scaling configuration also supports the new system disk limit. If necessary, you can go to the elastic scaling console to configure a new scaling configuration

- When using the same configuration to purchase ECS by volume:
The system disk is 40GB and the price is 1.06 RMB/hour
The system disk is 20GB and the price is 1.05 RMB/hour
When you purchase an ECS by volume, you can choose a smaller 20G system disk than a 40G system disk before
Cheap 0.01 * 24 * 30 = 7.2 RMB/month (not considering the impact of other discounts)
