Curve is a cloud-native distributed storage system developed by NetEase and hosted as a CNCF sandbox project, supporting both block storage (CurveBS) and POSIX-compatible shared file storage (CurveFS). It emphasizes high performance with RDMA+SPDK, easy operation, and hybrid cloud tiering of hot and cold data.
Use cases
- deploy distributed block storage for virtual machine and container persistent volumes
- provide POSIX-compatible shared file storage for AI training workloads
- tier hot data on-premises and cold data to public cloud object storage
- build storage-compute separation architecture for databases like MySQL and Kafka
- replace proprietary cloud disks with self-hosted high-performance storage
- run cost-effective shared file storage on public cloud
When to choose
- you need self-hosted distributed block or file storage with cloud-native deployment
- you want high-performance, low-latency storage using RDMA and SPDK
- you need hybrid tiering between local IDC and public cloud
- you want a CNCF-hosted, Kubernetes-friendly storage system
When to avoid
- you only need simple single-node local storage
- you require a fully mature CNCF graduated project with large ecosystem
- your workload is Windows or macOS based
- you need object storage as the primary interface
