Cloud Storage Description

CAE supports parallel file system, bucket, and Scalable File Service Turbo (SFS Turbo). Table 1 describes the features and application scenarios of them.

SFS Turbo is available in CN East-Shanghai1, CN South-Guangzhou, AP-Singapore, LA-Mexico City2, ME-Riyadh, and TR-Istanbul.

Dimension	OBS Parallel File System	OBS Bucket	SFS Turbo
Definition	Parallel File System (PFS) is a high-performance system with access latency in milliseconds. Provided by OBS, PFS supports bandwidth up to the TB/s level and millions of IOPS for processing high-performance computing (HPC) workloads.	A bucket is a container for storing objects in OBS. It provides massive, secure, reliable, and cost-effective data storage.	SFS Turbo provides scalable, high-performance shared file storage (NAS) for shared file access from ECSs, Cloud Container Engine (CCE) containers, and Bare Metal Servers (BMSs).
Data storage logic	Stores files but supports object APIs. That is, you can process files the same way you process objects, implementing the interworking between objects and files.	Stores objects. Files directly stored automatically generate the system metadata, which can also be customized by users.	Stores files. Files stored in SFS can be shared by multiple ECSs, CCE and CCI containers, and BMSs. SFS also allows you to seamlessly access objects stored in OBS buckets to implement data synchronization.
Features	Shared storage and user-mode file system. High-performance storage services are provided.	Shared storage and user-mode file system. You can configure the object storage class as required.	File sharing, elastic scalability, high performance, high reliability, seamless integration, easy operation, and low cost.
Application scenario	High-performance computing and media asset archiving, such as video surveillance, online video on demand (VoD), HPC, and big data	Big data analytics, static website hosting, VoD, gene sequencing, intelligent video surveillance, backup and archiving, and enterprise cloud boxes (web disks)	AI training, AI generated content, autonomous driving, rendering, EDA simulation, and enterprise NAS applications
