vCenter Virtual Server Disks

Virtual server storage is provided by disks. A disk is a partition of a data store that is allocated to a specific virtual server. Disk can be set as primary (that is, the disk from which an OS will boot).
Managing disks for the entire cloud is handled through the Control Panel's Settings menu. Disks for individual virtual servers are managed through the Control Panel > Cloud > Virtual Servers menu, where you can:

• See the list of disks allocated to this VS
• Add a new disk
• Resize a disk  
• Check disk usage statistics (IOPS)
• Delete a disk
