Storage Class and Performance Specification
Last updated: 2021-06-02 16:31:53
CFS introduces various file system types. The following table describes the features, advantages, and use cases of each type.
| Product Type | Standard | High-Performance | ||
| Storage Class | Standard | Standard Turbo | High-Performance | High-Performance Turbo |
| Positioning | Cost-effective, suitable for most scenarios | High OPS and high throughput, suitable for large and small files under high load | High bandwidth, suitable for large files and high throughput scenarios | High OPS and low latency, suitable for latency-sensitive businesses under high load |
| Scenario | Small-scale enterprise file sharing, web services, data backup/archive, and log storage | High-performance and large-scale web services, media, image rendering, AI reference, OLAP services, and high-performance computation | High-performance and large-scale web services, media, image rendering, and AI inference | High-performance and large-scale computation, AI training, databases, big data analysis, and OLAP services |
| Storage capacity | 0−160 TiB | 40 TiB−100 PiB | 0−10 PiB | 20 TiB−100 PiB |
| Bandwidth (MiB/s) | Min [100 + Storage usage in GiB x 0.1,300] | Min [Storage usage in GiB x 0.1,102,400] | Min [200 + Storage usage in GiB x 0.2,10,240] | Min [Storage usage in GiB x 0.2,102,400] |
| Latency | 4K single-stream read/write: 3 ms/7 ms | 4K single-stream read/write: 0.2 ms/3 ms | 4K single-stream read/write: 1 ms/1.5 ms | 4K single-stream read/write: 0.2 ms/1.5 ms |
| OPS | Read/Write: 10k+/1k+ | Read/Write (40T cluster): 150k/10k (linear growth) | Read/Write: 10k+/1k+ | Read/Write (20T cluster): 150k/10k (linear growth) |
| Cost | 0.058 USD/GiB/month | 0.09 USD/GiB/month | 0.23 USD/GiB/month | 0.15 USD/GiB/month |
| Supported protocol | NFS/SMB | POSIX/MPI | NFS/SMB | POSIX/MPI |
| Expansion | Auto | Manual | Auto | Manual |
| Supported OS | Linux/Windows | Linux | Linux/Windows | Linux |
- The table above shows the capabilities of the file system. To reach the performance upper threshold, you usually need to perform multi-threaded reads/writes using multiple compute nodes.
- The High-Performance storage class is still in beta testing and thus is not available yet.
