Commercial use General Purpose SSD EVS Disks March 2019 No. Feature Description Phase Document 1 EVS disk monitoring is supported. You can view monitored EVS disks.
For the endpoint of the EVS service, see Regions and Endpoints. Parent Topic: Before You Start
Figure 3 Data rebuild principle What Are the Differences Between Three-Copy Redundancy, EVS Snapshots, and EVS Backups? Three-copy redundancy improves the reliability of the data stored on EVS disks.
Step 1: Purchase an EVS Disk Buy a data disk on the EVS console. Step 2: Attach the EVS Disk Attach the data disk to a Linux server. Step 3: Initialize the EVS Disk Initialize the data disk on the server. Preparations Sign up with Huawei Cloud.
Different types of EVS disks can be attached to the same server. You only need to make sure that these disks and the server are in the same AZ. Parent topic: Attachment
If the disk was purchased on the EVS console and not as part of the same order as any server, it can be attached to another server. Parent topic: Attachment
EVS disks can be created only based on snapshots, and snapshots cannot be rolled back to source EVS disks.
Table 1 System-defined roles and policies supported by EVS Role/Policy Name Description Type Dependencies EVS FullAccess Full permissions for EVS. Users granted these permissions can create, attach, detach, query, and delete EVS resources, and expand capacity of EVS disks.
Table 1 API overview Type Subtype Description API EVS disk These APIs provide the functions, such as creating disks, deleting disks, and querying disk details. EVS snapshot An EVS snapshot is a complete copy or image of the disk data at a specific time point.

Switch back to the Elastic Volume Service page. Check whether the EVS disk is successfully created. It takes more than 10 minutes to create an EVS disk using a VBS backup.

For a BMS, a maximum of 60 EVS disks (1 system disk and 59 data disks) are supported. Only SCSI disks can be attached.
In the list, select Elastic Volume Service (EVS) for Service Type. In the Resource Tag column, find the _sys_recycle_bin_volume:true tag, which identifies the EVS recycle bin bill.
An EVS disk can be expanded either in the Available or In-use state. Expanding the disk capacity on the management console enlarges the disk capacity, but you still need to log in to the server and extend the disk partitions and file systems to make that additional space usable.
Creating a VBS Backup You can create backups for your EVS disks to protect the disk data through the VBS console or the EVS console. Precautions An EVS disk can be backed up only when its status is Available or In-use.

EVS is used to store DDS instance data. For details about EVS, see Elastic Volume Service User Guide. DDS instance backup data is stored in OBS and does not count towards your DDS storage quota.
If this still fails to meet your needs, it is recommended that you create RAID arrays with EVS disks or manage EVS disks using LVM. Parent topic: Capacity
