What is NAS

Last Updated: May 11, 2018

Alibaba Cloud Network Attached Storage (NAS) is a highly reliable and available file storage service. It features a distributed file system with unlimited capacity and performance scaling, with namespace and multiple client access support. NAS supports standard file access protocols (NFSv3, NFSv4, and SMB), so existing applications do not need to be modified.

After creating a NAS file system and mount point, you can mount the file system to computing nodes (such as Alibaba Cloud ECS, E-HPC, or Container Service) using the NFS or SMB protocol, and then use Portable Operating System Interface (POSIX) to access the file system. Multiple computing nodes can be simultaneously mounted to the same file system to share files and directories.
