NAS - network attached storage devices satisfy the requirements of users looking for a platform for sharing large amounts of data. They allow access to data via file access protocols such as CIFS/SMB, NFS, AFP or FTP.
NAS servers as an operating system, managing data, mainly use Linux, as well as Windows, with special emphasis on Windows Storage Server. They can be successfully used as:
- NAS server
- Backup server
- File server
- Disk array
- Print server
- Application server
By combining a server platform with disk shelves, capacity growth can be easily managed. All you need to do is add more disks or new disk shelves.
In addition to server solutions with a traditional operating system providing NAS functionality, specialized disk arrays are available on the market, where network storage functions are implemented in firmware. Compared to traditional solutions, they provide higher performance and usually also have the functions of a traditional disk array with access via block protocol iSCSI, FC or FCoE.
NAS solutions are also increasingly offering a Cloud Gateway function allowing data to be stored in popular public cloud services like Amazon, Azure and many others.
