Functions

This section describes functions of SFS Turbo. You can check if a certain function is available in a region on the console.

NFS Protocol

Network File System (NFS) is a distributed file system protocol that allows different computers and operating systems (OSs) to share data over a network. After the NFS client is installed on each ECS, you can mount the file system to implement file sharing between ECSs. NFS is recommended for Linux clients. For more information, see Mounting an SFS Turbo File System to Linux ECSs.

SMB Protocol

Server Message Block (SMB) is a protocol used for network file access. Using SMB, network files can be shared between Windows hosts. It enables Windows clients to identify and access shared resources provided by the storage system. Through it, clients can read, write, and create files in the file system the same way as on local PCs. SMB is recommended for Windows clients. For more information, see Mounting an SFS Turbo File System to Windows ECSs. Submit a service ticket to apply for using this protocol.

File System Management

File systems are containers that store files in SFS Turbo. You can create, view, and delete SFS Turbo file systems. For more information, see File System Management.

Permissions Management

SFS Turbo uses Identify and Access Management (IAM) for permissions management. You can control the read and write permissions of file systems by granting IAM users fine-grained SFS Turbo permissions using IAM custom policies. For more information, see Permissions.

Backup

A backup is a complete copy of a file system at a specific time. It records all configuration data and service data at that time. If your file system is faulty or a logical error occurs on data in the file system, you can use a backup to quickly restore data. For more information, see Backing Up an SFS Turbo File System.

Encryption

You can encrypt data on the newly created SFS Turbo file systems if needed. For more information, see Creating and Unmounting an Encrypted File System.

Capacity Expansion

You can expand the capacity of a file system if needed. For more information, see Expanding Capacity of an SFS Turbo File System.

Active Directory Domain

Active Directory Domain Services (AD DS) is a directory service that provides unified identity and permissions management through domain networks. After adding an SFS Turbo file system to an AD domain, you can authenticate user identities and manage permissions by file in that domain. For more information, see Configuring an AD Domain. Submit a service ticket to apply for using this function.

LDAP Domain

Lightweight Directory Access Protocol (LDAP) is a standard protocol for interacting with directory servers. An LDAP server can centrally manage the ownerships of users and groups. After you bind your file system to an LDAP server, when a user accesses a file in the file system, SFS Turbo will access your LDAP server for user authentication and obtain the user and group ownerships. For more information, see Configuring an LDAP Domain.

Synchronous Replication (Cross-AZ DR)

Synchronous replication allows you to deploy file systems across AZs. It sets up standby servers and data remotely and ensures crash consistency for data. If your active file system fails due to force majeure (tsunamis, fires, earthquakes, or other natural disasters) or device faults (software or hardware damages), the standby file system in the standby AZ can take over services. After the active AZ recovers, you can switch back to the active file system. Submit a service ticket to apply for using this function.

Monitoring

Cloud Eye is a multi-dimensional resource monitoring service. With Cloud Eye, you can view the file system usage and service running status, and respond to exceptions in a timely manner. For more information, see Monitoring SFS Turbo File Systems Using Cloud Eye.

Auditing

Cloud Trace Service (CTS) records operations performed on SFS Turbo file systems, facilitating query, audit, and backtracking. For more information, see Auditing SFS Turbo File Systems Using CTS.

Enterprise Project

An enterprise project manages multiple resources by category. Resources and projects in different cloud service regions can be classified into one enterprise project. For example, an enterprise can classify resources based on departments or project groups and then put relevant resources into the same enterprise project for management. Resources cannot be migrated between enterprise projects. For more information, see Project and Enterprise Project.
