Cloud disks, also known as data disks, can be purchased from the ECS Management Console. Each user account can own up to 250 cloud disks simultaneously. Up to 16 data disks can be attached to any single ECS instance, with a maximum capacity of 32768 GB per data disk.
To purchase a cloud disk, perform the following:
Log on to the ECS console.
Click Cloud Disks in the left-side navigation pane.
Select your desired region, then click Create Cloud Disk in the top-right corner of the page.
Select a region and zone.
Note: A cloud disk can be attached to only a server in the same zone of the same region. Cloud disks do not support cross-regional functionality.

For Linux instances, cloud disks must be attached, partitioned, and formatted before they can be displayed and used in the system.
