Storage Area Network (SAN); a Dedicated Network of Storage Devices Used To Provide A Pool of Shared Storage
Storage Area Network Storage Area Network (SAN) is a specialized, high-speed network that provides network access to storage devices. SAN is a network of storage devices that can be accessed by multiple servers or computers, providing a shared pool of storage space. Each computer can access storage on the SAN as though they were local disks connected directly to the computer. A SAN allows us to combine many file-systems into a single disk array, allowing far more efficient use of storage resources. Because SAN is block level, it is able to do this anytime that a traditional, local disk subsystem could be employed. Storage Area Network is a modular computer network that provides centralized, file-level access to multiple, fixed-size block storage. It is a dedicated, independent network that interconnects and distributes a shared pool of storage devices to multiple servers. It is mostly used to access large data storage devices, including tape libraries and disk arrays, from mul...
