You can create a subscription or pay-as-you-go data disk to increase the storage space of your Elastic Compute Service (ECS) instance.
Background information
The following table describes the limits that apply to disks that use different billing methods.
Disk | Limits |
---|---|
Pay-as-you-go disk |
|
Subscription disk |

In addition, you must take note of the following items:
- Disks are independent of each other and cannot be merged by formatting. Therefore, we recommend that you determine the number and capacity of disks that you need before you create them.
- We recommend that you do not use Logical Volume Manager (LVM) to create logical volumes on multiple disks. This is because a snapshot can back up the data only of a single disk. If you create a logical volume on multiple disks by using LVM, data discrepancies may occur when you roll back these disks.
