Overview

CCI supports multiple types of persistent storage to meet your requirements in different scenarios. 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. EVS volumes are ideal for persistent data storage. For details, see EVS Volumes.

    When using EVS volumes to store data, pay attention to the following points. Otherwise, pods cannot run properly.

    • You cannot mount an EVS volume to multiple pods.
    • You cannot mount a pod to EVS volumes with multiple partitions.
  • Scalable File Service (SFS) volumes

    You can create SFS volumes and mount them to specific container paths. The volumes created by the underlying SFS service can also be used. SFS volumes are ideal for workload scenarios where data persistence is required and data needs to be read by and written to multiple nodes. Such scenarios include media processing, content management, big data analysis, and workload analysis. For details, see SFS Volumes.

  • SFS Turbo volumes

    You can create SFS Turbo volumes and mount them to specific container paths. SFS Turbo volumes are fast, on-demand, and scalable. They are suitable for DevOps, containerized microservices, and enterprise office applications. For details, see SFS Turbo Volumes.

    Currently, SFS Turbo volumes are unavailable in region CN East-Shanghai1.

  • Object Storage Service (OBS) volumes

    You can mount OBS volumes to specific container paths. OBS is a cloud storage service that provides massive, secure, highly reliable, and low-cost data storage capabilities. For details, see OBS Volumes.

PersistentVolumeClaim (PVC)

CCI uses PVCs to apply for and manage persistent storage. With PVCs, you only need to specify the type and capacity of storage resources and do not need to worry about how to create and release underlying storage resources.

You can bind a PVC to the volume in a pod and use persistent storage through the PVC, as shown in Figure 1.

Figure 1 Using persistent storage

On the CCI console, you can import existing EVS disks, SFS file systems, and SFS Turbo file systems. When you import these storage resources, CCI creates a PVC for the resource.

You can also purchase EVS disks and SFS file systems on the CCI console. After you complete purchasing these storage resources, CCI will create PVCs for them and import them.
