Overview
What is NAS File System ?
File Storage NAS is a file storage service for FLOU Cloud ECS instances, Container Service. It provides standard file access protocols. This enables you to have a distributed file system with unlimited capacity and performance scaling.
Features of NAS File System
- 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.
Benefit of NAS File System
- 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.
