Storage Area Network
A Storage Area Network (SAN) is a high-speed network of storage devices that enables efficient data transfer and management for computers and virtual machines (VMs). It provides block-level access to data, allowing multiple servers to access shared storage resources as if they were directly attached to their local storage. This architecture centralizes and streamlines data management, improving scalability, performance, and availability compared to direct-attached storage (DAS) or network-attached storage (NAS) solutions. SANs are particularly beneficial in enterprise environments where large amounts of data need to be processed, managed, and protected across servers and VMs. They can also facilitate disaster recovery strategies by allowing for remote replication and backup of critical data assets. In the hierarchy of Electronics/Computers/VM/Storage, a SAN represents an advanced storage solution that enhances the functionality, efficiency, and reliability of data management within the broader context of computer systems and virtual environments.
