File System Types
SFS provides three types of file systems: SFS Capacity-Oriented, General Purpose File System, and SFS Turbo.
The following table describes the features, advantages, and application scenarios of these types of file systems.

Highlights |
Application Scenarios |
---|---|---|---|---|
SFS Capacity-Oriented |
- |
NOTE:
|
Large capacity, high bandwidth, and low cost |
Cost-sensitive workloads which require large-capacity scalability, such as media processing, file sharing, high-performance computing, and data backup. For workloads dealing with massive small files, SFS Turbo is recommended. |
General Purpose File System |
- |
|
Large capacity, high bandwidth, and low cost |
Cost-sensitive workloads which require large-capacity scalability, such as media processing, file sharing, high-performance computing, and data backup. For workloads dealing with massive small files, SFS Turbo is recommended. |
SFS Turbo |
Standard (supporting NFS only) |
|
Low latency and tenant exclusive |
Workloads dealing with massive small files, such as code storage, log storage, web services, and virtual desktop |
Standard-Enhanced (supporting NFS only) |
|
Low latency, high bandwidth, and tenant exclusive |
Workloads dealing with massive small files and those requiring high bandwidth, such as code storage, file sharing, enterprise office automation (OA), and log storage. |
|
Performance (supporting NFS only) |
|
Low latency, high IOPS, and tenant exclusive |
Workloads dealing with massive small files, and random I/O-intensive and latency-sensitive services, such as high-performance websites, file sharing, and content management |
|
Performance-Enhanced (supporting NFS only) |
|
Low latency, high IOPS, high bandwidth, and tenant exclusive |
Workloads dealing with massive small files, and latency-sensitive and bandwidth-demanding workloads, such as image rendering, AI training, and enterprise OA. |
|
20 MB/s/TiB |
|
Large capacity and low cost |
Enterprise OA and code repository management |
|
40 MB/s/TiB |
|

|
250 MB/s/TiB |
|
Low latency and high bandwidth |
AI training, EDA simulation, gene analysis, and video rendering |
|
500 MB/s/TiB |
|
Low latency and high-density performance |
Autonomous driving, AI generated content, and EDA in chip design |
|
1,000 MB/s/TiB |
|
Low latency and high-density performance |
Autonomous driving, AI generated content, and EDA in chip design |

The performance of an SFS Turbo file system is proportional to the purchased capacity. The higher the file system capacity, the higher the bandwidth. Based on the bandwidth provided by each 1 TB of capacity, SFS Turbo file systems are classified into the following types: 20 MB/s/TiB, 40 MB/s/TiB, 125 MB/s/TiB, 250 MB/s/TiB, 500 MB/s/TiB, and 1,000 MB/s/TiB.
For example, if you buy a 250 MB/s/TiB file system with a capacity of 6 TB, the bandwidth that this file system can provide is 1,500 MB/s (250 x 6).
The minimum bandwidth of an SFS Turbo file system is 150 Mbit/s. If the calculated bandwidth is less than 150 Mbit/s, 150 Mbit/s will be used as the bandwidth of this file system. There will also be a maximum bandwidth for each type of SFS Turbo file systems. If the calculated bandwidth is greater than the maximum bandwidth, the maximum bandwidth will be used as the bandwidth of this file system.
