What Is EVS Capacity Expansion?

If the capacity of an existing EVS disk is insufficient, you can expand the disk capacity to increase storage space.

Expansion Upper Limits

The disk capacity can only be expanded, not reduced. The maximum disk capacity is as follows:

System disk: 1 TiB
Data disk: 32 TiB

NOTE:

If you detach a system disk and then attach it to another server as a data disk, the maximum capacity of this disk is still 1 TiB.

How Do I Expand the Disk Capacity?

You can expand the capacity of an EVS disk in two steps:

Step 1: Expand Disk Capacity

Step 2: Extend Disk Partitions and File Systems

NOTE:

If the server is stopped during the expansion, the additional space of a Windows system disk, Windows data disk, or Linux system disk may be automatically added to the last partition after the server is started. In this case, the additional space can be directly used. If the additional space is not automatically added, you need to extend the partition and file system according to the preceding steps.

Capacity Expansion Charges

You will be billed for the additional capacity of a disk after you expand the disk capacity. The billing mode of the additional capacity is the same as that of the disk.

For a pay-per-use disk: The new capacity takes effect immediately, so you will be billed for the new capacity of the disk immediately.
For a yearly/monthly disk: You need to pay for the price difference after expanding the disk capacity. The disk expiration time remains unchanged.

For details about EVS billing, see Billing for EVS Disks.
