A Storage area network (SAN) is a type of network for connecting external storage devices to servers. The operating system treats these devices as directly connected. A SAN usually operates as a dedicated network separate from the LAN.
A SAN is predominantly used to provide block devices. A SAN facilitates efficient and convenient storage and retrieval of data for enterprise-level applications.
Modern SAN configurations include hybrid networks that offer traditional block storage that acts as local storage and object storage for Web services via APIs. This upgrade has made the SAN even more versatile and useful for a wide range of applications, especially those that require high flexibility and scalability. All of this allows for secure and reliable data transfer.
