Storage and Backup Solution for SMB - NAS (Network Attached Storage): NAS is a method of remote file serving. Rather than using the software on your own file system, file access is redirected to another device using a remote protocol, such as CIFS or NFS - operating as a server of some type with its own file system - to do the file I/O on your behalf. This enables file sharing and centralized data management.
Storage Solution for Enterprise - SAN (Storage Area Network): SAN is a dedicated network of storage devices (can include Tape Drives storages, Raid Disk arrays etc.) all working together to provide an excellent block level storage.
