Scalable capacity

NAS provides scalable file systems. You can add file systems to increase the storage capacity, or delete file systems to decrease the storage capacity.

Shared access

NAS allows shared access to the same data source in a file system from multiple compute nodes and uses file locks to ensure data consistency.

Protocol compatibility

NAS Supports standard protocols, such as NFS (NFSv3.0 and NFSv4.0) and SMB (SMB 2.1 and SMB 3.0). NAS also supports mainstream operating systems, such as Linux and Windows.

Access control and compliance

Based on Resource Access Management (RAM) authentication, NAS provides VPC-based isolation and security group-based access control to ensure data security

Data encryption

NAS provides data encryption to prevent user data from being intercepted or sniffed during data transmission

Flexible access modes

NAS allows you to access file systems from various networks, such as VPCs, on-premises IDCs, and dedicated networks

Data transmission

NAS supports synchronous or asynchronous data transmission between NAS file systems or between NAS and Object Storage Service (OSS) by using Data Transmission Service (DTS)

Data backup

NAS generates multiple replicas for data based on flexible backup policies. These replicas are used to restore corrupted data

Cost-effectiveness

NAS allows you to pay only for the storage space that you consume without the need to configure storage in advance

Ease of use

You can create a file system in a few clicks without the need to deploy and maintain the file system

Security

NAS provides access control based on Resource Access Management (RAM), and access isolation based on virtual private clouds (VPCs) supports encryption in transit and at rest

High reliability

NAS provides multiple replicas for each data entry that is stored in a file system that resides in isolated devices across different fault domains for geo-redundancy

High performance

NAS provides a distributed file system whose performance linearly scales with capacity and a higher level of storage performance

Compatibility

NAS supports standard protocols, such as Network File System (NFS) and Server Message Block (SMB), ensures data consistency, and file locking based on POSIX APIs
