The EVS must be in the available status. The EVS disk and the target ECS must be located in the same AZ. VBD EVS disks cannot be attached to BMSs. URI POST /v2.1/{project_id}/servers/{server_id}/os-volume_attachments Table 1 describes the parameters in the URI.
EVS disks If an EVS disk (a system disk or a data disk) is created with a spot instance, this EVS disk is billed on a pay-per-use basis.
Buy an Elastic Volume Service (EVS) disk for each ECS and attach it to each ECS as the data disk if required. ECS VPC (Optional) EVS The number of servers is dynamically adjusted as incoming traffic changes over time.
Note the following when using the two types of storage media (local disks and EVS disks): Only an EVS disk can be used as the system disk of a D7 ECS. Both EVS disks and local disks can be used as data disks of a D7 ECS.
Xrole Name: set to EVSAccessKMS, which means that permissions have been assigned to EVS to obtain KMS keys for encrypting or decrypting EVS disks. KMS Key Name: specifies the name of the key used by the encrypted EVS disk.
NOTE: For details about IOPS of GPSSD2 and ESSD2 EVS disks, see Disk Types and Performance. Only pay-per-use billing is supported currently. throughput No Integer Specifies the throughput of an EVS disk. The unit is MiB/s.
Pay-per-Use to Yearly/Monthly Yearly/Monthly to Pay-per-Use EVS disk Changing the billing mode independently from the ECS billing mode is not supported. You must attach an EVS disk to an ECS and initiate the change on the ECS side.

All regions Changing a VPC ECS Data Backup Cloud Backup and Recovery (CBR) backs up data for EVS disks and ECSs, and uses snapshot backups to restore the EVS disks and ECSs.
Auto renew is provided for the ECSs and EVS disks when you purchase them. To enable automatic renewal for EIPs, perform the following operations: Log in to the management console and click Billing > Renewal in the upper right corner. The Renewals page is displayed.

If you use both ECS and EVS recycle bins, you are advised to configure the same minimum number of days for moving ECSs and EVS disks to the recycle bins to avoid issues brought by different lifecycles. For details, see Recycle Bin Policy Configuration Suggestions.
After creating the ECS, you can view the tags on the pages providing details about the ECS, EIP, and EVS disks. Basics of Tags Tags are used to identify cloud resources.
Prerequisites Before restoring data, complete the following preparations: Back up data by referring to Creating an EVS Snapshot and Creating a Private Image to ensure that data can be restored to its original state if an error occurs during data restoration.
Figure 1 Disk attachment Possible Causes If an EVS disk in arrears is not renewed, the system forcibly uninstalls it, which may cause a residual drive letter on the Windows ECS.
Public services, such as Elastic Cloud Server (ECS), Elastic Volume Service (EVS), Object Storage Service (OBS), Virtual Private Cloud (VPC), Elastic IP (EIP), and Image Management Service (IMS), are shared within the same region.
Otherwise, resources, such as vCPUs, memory, and EVS disks, will be automatically released, and data will be lost and cannot be restored. On the ECS console, locate the ECS you want to renew and choose More > Renew in the Operation column.

Purchasing and Using an ECS (Old Edition) Scenarios Elastic Cloud Server (ECS) is a cloud server that provides scalable, on-demand computing resources, including vCPUs, memory, OS, and Elastic Volume Service (EVS) disks.
