Network Attached Storage

NAS is a file storage service for computing nodes such as cloud servers and Docker, which can provide a standard file access protocol, enabling users to use the distributed file system characterized by unlimited capacity, performance extension, single namespace, multiple sharing, high reliability and high availability without any modification of the existing applications.

Product Functions

Seamless integration
Standard file system semantics is adapted to access data. Mainstream applications and workloads can be used cooperatively and seamlessly without any modification
Shared access
Multiple computing nodes can access the same file system instance simultaneously, making it ideal for applications that access the same data source across multiple cloud servers, HPC, Docker and other deployments
Security management
A variety of security mechanisms including virtual private cloud (VPC), standard authority control of file system, access control of authority groups and master-account/ sub-account authorization work together to ensure that the data of file system are perfectly safe
Linear extensibility
High-throughput, high-IOPS and low-delay storage performance are provided for the application workload. Meanwhile, the linear relationship between performance and capacity can meet the increased demands for capacity and storage performance caused by business growth

Product Advantages

Multiple sharing
The same file system can be mounted on various computing nodes simultaneously so that sharing access can be realized and a lot of copy and synchronization costs can be saved
High reliability
99.99999999% reliability of data can be realized, and a large number of maintenance costs can be saved compared with self-built NAS storage; risks of data security can be reduced as well
Elastic expansion
The upper limit of a single file system can reach 10 PB. Payment is made according to actual usage, making it easy to cope with business expansion and shrinkage at any time
High performance
The throughput performance of a single file system can expand linearly with the amount of storage, which can significantly reduce the cost compared with buying high-end NAS storage devices
Easy to use
Supportive of NFSv3 protocol and NFSv4 protocol, making it feasible to access the file system through the standard POSIX interface, whether in a cloud server or a computing node such as Docker

Application Scenarios

Load balancing shared storage and high availability
In the scenario of load balancing connecting multiple cloud servers, data in the applications of cloud servers can be stored in a shared NAS, so that the data can be shared and load balancing can be highly available
File sharing
If it is necessary to access and share the same data set, an administrator can create a NAS file system providing data access to individuals in the organization and set permissions for users and groups at the file or directory level
Data backup
Users wish to back up offline data to the cloud and also require that the storage services on the cloud be compatible with the standard file access interfaces
Server log sharing
Application server logs on multiple computing nodes are stored in a shared NAS, to facilitate centralized processing and analysis of subsequent logs
