Network-attached storage (NAS) is an IP-based file-sharing device attached to a local area network. NAS serves a mix of clients and servers over and IP network. A NAS device uses its own operating system and integrated hardware and software components to meet a variety of file service needs.
Network-attached storage (NAS storage) enables server consolidation by eliminating the need for multiple file servers and storage consolidation through file-level data access and sharing. NAS typically uses multiple protocols to perform filing and storage functions. These include TCP/IP for data transfer; SMB (CIFS) and NFS for remote file service; and NFS, SMB and FTP for data sharing.
Who uses network-attached storage, and why
Organizations across a wide range of industries use network attached storage (NAS) to:
How network-attached storage works
A NAS device is an open-system computer system with storage capacity connected to a network that provides file-based data storage services to other devices on the network. NAS uses standard file protocols such as SMB (Server Message Block) and Network File System (NFS) to allow Microsoft Windows, Linux, and UNIX clients to access files, file systems, and databases over the IP network.
