What is Network-attached Storage?

Network-attached Storage refers to a dedicated data storage device that enables data sharing among authorised clients and users connected to a network. Each NAS is assigned a unique IP address in the network where it is accessed by the users through a web interface. NAS has a file-level architecture, which means it stores and handles that data as files. NASs are highly scalable and easy to set-up. An additional NAS unit can be added to existing infrastructure without needing to make any changes to existing servers.

Points to Remember

  • NAS can store data in multiple file systems – such as Network File System (NFS), Common Internet File System (CIFS), Apple Filing Protocol (AFP), Server Message Block (SMB).
  • NAS units don’t rely on a fully-featured operating system, instead, they come equipped with an embedded streamlined operating system (OS). This OS is tailored to support NAS’ data storage and presentation functions and only run the software necessary for data protection and permission handling.
