Overview¶
Introduction¶
CCE allows you to mount a volume created from a Scalable File Service (SFS) file system to a container to store data persistently. SFS volumes are commonly used in ReadWriteMany scenarios for large-capacity expansion and cost-sensitive services, such as media processing, content management, big data analysis, and workload process analysis. For services with massive volume of small files, SFS Turbo file systems are recommended.
Expandable to petabytes, SFS provides fully hosted shared file storage, highly available and stable to handle data- and bandwidth-intensive applications
Standard file protocols: You can mount file systems as volumes to servers, the same as using local directories.
Data sharing: The same file system can be mounted to multiple servers, so that data can be shared.
Private network: Users can access data only in private networks of data centers.
Capacity and performance: The capacity of a single file system is high (PB level) and the performance is excellent (ms-level read/write I/O latency).
Use cases: Deployments/StatefulSets in the ReadWriteMany mode and jobs created for high-performance computing (HPC), media processing, content management, web services, big data analysis, and workload process analysis
Application Scenarios¶
SFS supports the following mounting modes based on application scenarios:
Using an Existing SFS File System Through a Static PV: static creation mode, where you use an existing SFS volume to create a PV and then mount storage to the workload through a PVC. This mode applies to scenarios where the underlying storage is available.
Using an SFS File System Through a Dynamic PV: dynamic creation mode, where you do not need to create SFS volumes in advance. Instead, specify a StorageClass during PVC creation and an SFS volume and a PV will be automatically created. This mode applies to scenarios where no underlying storage is available.
