    High performance

    Based on the newest distributed storage system, NAS maintains a low latency and high IOPS

    
    

    High reliability

    Maintains multiple data replicas and a data reliability of 99.999999999%. NAS is more reliable than traditional RAID arrays.

    
    

    High availability

    Avoids single points of failure and maintains a data availability of 99.9%.

  Unlimited, Elastic Storage

  • 
    

    Elastic scaling provides great scalability to meet your needs

    
    

    Unlimited storage capacity

    The maximum capacity of a file system can reach 10 PB. Each file system can store a maximum of 1 billion files, and the maximum file size is 32 TB.

    
    

    Elastic scaling

    Storage scales automatically and is billed accordingly. This is a fully hosted solution that needs no upfront cost.

    
    
• 

  Ease of Use. You Can Perform File Operations as If the Files Were Locally Stored

  • 
    

    Supports POSIX interfaces. No modifications need to be made to your applications.

    
    

    Simple and easy to use

    Supports standard POSIX interfaces. Both Windows and Linux applications can use this service without any modifications.

    
    

    System mounting

    You can mount the file system on ECS compute nodes. This allows you to perform file operations as if the files were locally stored.

    
    
• 

  Supports Various Standard Protocols

  • 
    

    Supports standard NFS and SMB protocols. Both Windows and Linux applications can use this service.

    
    

    NFS

    Supports the NFSv3 and NFSv4 protocols and provides standard file system semantics for data access. Most mainstream applications and tasks can be seamlessly integrated with the service without any modifications.

    
    

    SMB

    Supports the SMBv2.0, SMBv2.1, and SMBv3.0 protocols. Supports the applications that are deployed on Windows Vista, Windows Server 2008 and later versions.

    
    
• 

  Strong Security Control

  • 
    

    Mechanisms such as account authorization, VPC, and security groups ensure your data security.

    
    

    Data security

    Multiple security mechanisms are implemented to guarantee system data security, including network isolation (VPC) and user isolation (classic network), standard access control, permission groups, and account authorization.

    
    
• 

  Multiple Access Methods

  • 
    

    Supports classic network and VPC, and allows access from remote data centers.

    
    

    Shared access

    Multiple compute nodes can simultaneously access the same file system, allowing applications deployed across multiple ECS instances, E-HPC or Docker clusters to access the same data source.

    
    

    Multiple access methods

    The NAS file system can be deployed in a classic network or a VPC. You can also access the file system from remote data centers through leased lines or VPN.

    
    

    Access across multiple zones

    Supports access from different zones. Your ECS instance and NAS file system can be deployed in different zones.
