Cloud Parallel File Storage (CPFS) is ideal for high-performance computing (HPC) scenarios, such as AI training and genomics computing. You can mount a CPFS file system to a container as a persistent volume to provide persistent and shared storage.
CPFS overview
CPFS is a fully managed and scalable parallel file system from Alibaba Cloud. It provides high throughput and high input/output operations per second (IOPS) to meet the demands of HPC scenarios. In ACK clusters, only the CPFS general-purpose edition is supported.
Specifications
The CPFS general-purpose edition supports two storage specifications: the 100 MB/s/TiB baseline and the 200 MB/s/TiB baseline. For more information about the performance of each specification, see CPFS product specifications. You can select a specification based on your needs.
Only CPFS-NFS is supported in ACK clusters. CPFS-POSIX is not supported.
Billing
You are charged for using CPFS general-purpose file systems. For more information about billable items and billing methods, see Billing overview.
Scenarios
CPFS is suitable for HPC scenarios that require high throughput, high IOPS, and the ability to process a massive number of files. These scenarios include AI training, autonomous driving, genomics computing, electronic design automation (EDA) simulation, oil and gas exploration, and meteorological analysis.
Limits
The CPFS general-purpose edition is available only in select regions. For more information, see Available regions for the CPFS general-purpose edition.
CPFS file systems can be mounted only to clusters within the same VPC.
For more information about the limits of CPFS, see Limits.
Instructions
In ACK clusters, you can mount CPFS general-purpose file systems using the NFS protocol. Only static persistent volumes are supported. Dynamic provisioning of volumes is not supported. For more information, see Use a static persistent volume for the CPFS general-purpose edition.
