You can use an EVS volume only as a new disk. The content in the EVS volume that has not been mounted to CCI is invisible to the container. If you delete an imported EVS disk from the EVS console, it cannot be detected by CCI.
Data can be stored in volumes provided by Huawei Cloud storage services, including Elastic Volume Service (EVS) and SFS Turbo. All regions EVS Volumes SFS Turbo Volumes Add-on Management Add-ons are extension of the existing features.
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.

If no EVS disk or other cloud storage is mounted, the application data is stored in the physical machine disks of the container. Each pod can be allocated with a maximum of 20 GB disk of the CPU host or 20-GB disk of the GPU host for data storage.
Currently, CCI supports the following cloud storage types: EVS disks SFS Turbo file systems If an EVS disk is used, you need to manually configure a backup policy for it. For details, see VBS Backup Management. Parent topic: Storage Management FAQs
Alternatively, you can output logs to FlexVolume or persistent EVS or SFS volumes, and use a sidecar to run an open-source component such as Fluent Bit to report logs to your self-built log centers.
Using PersistentVolumeClaim to Apply for Persistent Storage CCI supports the following persistent storage services in containers: Elastic Volume Service (EVS) is a block storage service that provides three specifications: common I/O (previous-generation), high I/O (SAS), and ultra-high
It has the following values: sata: common I/O EVS volume sas: high I/O EVS volume ssd: ultra-high I/O EVS volume nfs-rw: Network File System (NFS) volume efs-performance: high-performance SFS Turbo volume efs-standard: standard SFS volume obs: OBS volume The reclaim policy is set
EVS Elastic Volume Service (EVS) provides persistent block storage. With data redundancy and cache acceleration technologies, EVS disks can deliver high-reliability, durable, stable performance with low latency.
Persistent Storage Volumes Data can be stored in Elastic Volume Service (EVS) and SFS Turbo. Excellent Auto Scaling Scaling policies can be user-defined to implement elastic scaling within 1 second.
The options are as follows: bs: EVS disk nfs: SFS file system NOTE: When deleteVolume is set to true, storageType is optional. When deleteVolume is set to false, storageType is mandatory.
Constraints on Pod Storage Space If no EVS disk is mounted, application data is stored in the rootfs of the container. The following table lists the storage space limit of each type of pod.
For CCI, Elastic Volume Service (EVS) disks can be mounted to containers. You only need to add EVS volumes, and configure their sizes and mount paths (that is, container volume paths) when creating workloads.

Currently, EVS and SFS Turbo volumes are supported. Click the EVS Volumes or SFS Turbo Volumes tab, and set the volume name, capacity, container path, and disk type. After the workload is created, you can manage the storage volumes.
You can use the following types of storage volumes when creating a workload: Elastic Volume Service (EVS) volumes You can mount an EVS volume into a container path. When the container is migrated, the mounted EVS volume is also migrated.
Storage types that can be used include Elastic Volume Service (EVS), Scalable File Service (SFS), and Object Storage Service (OBS). ConfigMap and Secret This section describes how to use ConfigMaps and secrets.
If a pod mounted with an EVS volume is deleted, the EVS disk will not be deleted. If a new pod with the same name is created, the new pod cannot be mounted to any EVS volume. Auto Scaling Currently, auto scaling is supported only for Deployments.
