File System Types

SFS provides two types of file systems: SFS Capacity-Oriented and SFS Turbo. SFS Turbo is classified into SFS Turbo Standard, SFS Turbo Standard – Enhanced, SFS Turbo Performance, and SFS Turbo Performance – Enhanced.

The following table describes the features, advantages, and application scenarios of these file system types.

**Table 1** Comparison of file system types
File System Type	Storage Class	Features	Highlights	Application Scenarios
SFS Capacity-Oriented	-	Maximum bandwidth: 10 GB/s; maximum IOPS: 10,000 Latency: 3 to 20 ms; maximum capacity: 4 PB Delivers better performance and suitable for services that require large capacity and high bandwidth.	Large capacity, high bandwidth, and low cost	Cost-sensitive workloads which require large-capacity scalability, such as media processing, HPC, and data backup.
SFS Turbo	SFS Turbo Standard	Maximum bandwidth: 150 MB/s; maximum IOPS: 5,000 Latency: 2 to 5 ms; maximum capacity: 32 TB Suitable for services with massive small files and services that require low latency.	Low latency and tenant exclusive	Workloads dealing with massive small files, such as code storage, log storage, web services, and virtual desktop
	SFS Turbo Standard - Enhanced	Maximum bandwidth: 1 GB/s; maximum IOPS: 15,000 Enhanced bandwidth, IOPS, and capacity	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.
	SFS Turbo Performance	Maximum bandwidth: 350 MB/s; maximum IOPS: 20,000 Latency: 1 to 2 ms; maximum capacity: 32 TB Delivers better performance and suitable for services with massive small files and services that require low latency.	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 and content management
	SFS Turbo Performance - Enhanced	Maximum bandwidth: 2 GB/s; maximum IOPS: 100,000 Enhanced bandwidth, IOPS, and capacity	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.
