CPFS General-purpose Edition is a fully managed, scalable parallel file system from Alibaba Cloud. It is designed for high-performance computing (HPC) workloads. CPFS General-purpose Edition provides a unified namespace, supports concurrent access from thousands of clients, delivers tens of GB/s of throughput and millions of IOPS, and ensures sub-millisecond latency.
Benefits
CPFS General-purpose Edition provides the following benefits:
-
High throughput: I/O bandwidth scales linearly with capacity. A single file system supports up to 20 GB/s.
-
High IOPS: Performance scales linearly with capacity, reaching up to 10 million IOPS for a single file system.
-
Low latency: Provides stable I/O with sub-millisecond latency.
-
Massive file storage: A fully symmetric metadata server architecture supports up to 10 billion files and over 100,000 metadata operations per second (OPS) in a single file system.
-
Low cost: Reduces storage costs through efficient dataflows with Object Storage Service (OSS). For more information, see CPFS dataflows.
-
Multi-protocol access: Supports both POSIX and NFS protocols, allowing multiple applications to access the same data. For more information, see protocol service.
-
Data isolation: Within a unified namespace, the NFS protocol supports directory-level mount targets. This simplifies data scheduling and isolates data between different services. For more information, see Manage export directories.
Key features
-
protocol service
CPFS General-purpose Edition supports the NFSv3 protocol and is interoperable with traditional POSIX clients. The NFS protocol provides improved operating system compatibility and compute elasticity, while still delivering the powerful throughput of CPFS General-purpose Edition. For more information, see protocol service.
-
Dataflow
CPFS supports dataflows with Object Storage Service (OSS). You can manage files in OSS buckets from the CPFS file system and access OSS data using POSIX interfaces. CPFS transparently loads data from OSS at the block level and caches it in the file system to accelerate access. No application modifications are necessary. For more information, see CPFS dataflows.
-
NFSv4 ACLs
CPFS file systems support NFSv4 access control lists (ACLs). You can use NFSv4 ACLs to grant read, write, and execute permissions to directories or files. For more information, see NFSv4 ACLs.
-
data monitoring
CPFS provides a data monitoring feature to view real-time information about your CPFS file system. You can monitor metrics such as file system performance, NFS protocol performance, file system capacity, and fileset capacity. For more information, see data monitoring.
Usage
You can create, use, and release CPFS file systems in the following ways:
-
Manage CPFS General-purpose Edition by using the console
Log on to the web-based CPFS console to manage your CPFS resources. For more information, see Getting started.
-
Manage CPFS by using an API or SDK. CPFS provides RESTful APIs and SDKs for various programming languages to quickly develop custom integrations. For more information, see Integration overview.
Service deactivation
-
After you enable the service, you cannot deactivate it directly. If you only enable the service but do not create a file system, you will not be charged.
-
If you have incurred charges and no longer want to use this service, see How do I stop billing for the CPFS service?. Note: Data in a deleted CPFS file system cannot be recovered.
