Storage Zone Network (SAN) is a high-speed network or subnet, providing data transmission between a computer and a storage system. The storage device refers to a disk device that stores computer data. A SAN network is responsible for the communication structure responsible for the network connection, responsible for organizing management, storage components, and computer systems, thereby ensuring the security and efforts of data transmission.
Typical SAN is part of a company's entire computer network resource. Usually SANs are closely integrated with other computational resources to implement remote backups and archive stored procedures. SAN supports disk mirroring, backup and restore, archive and retrieves of archive data, data migration between storage devices, and data sharing between different servers in networks. In addition, SANs can also be used to consolidate subnets and network attach storage (NAS: Network-attached storage) systems.
