NAS is often a single device made up of redundant storage containers or a redundant array of independent disks (RAID). SAN storage can be a network of multiple devices, including SSD and flash storage, hybrid storage, hybrid cloud storage, backup software and appliances and cloud storage.
A storage area network (SAN) or storage network is a computer network which provides access to consolidated, block-level data storage. SANs are primarily used to access data storage devices, such as disk arrays and tape libraries from servers so that the devices appear to the operating system as direct-attached storage .
A storage area network (SAN) is a dedicated high-speed network that makes storage devices accessible to servers by attaching storage directly to an operating system. It centralizes storage devices so they are easier to manage and communicate faster over media.
SAN Definition. A Storage Area Network (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 on the network can access storage on the SAN as though they were local disks connected directly to the computer.
Why is it called SAN? SAN is an acronym for storage area network. SANs consolidate storage in a single storage area separated from the local area network (LAN). Computers and devices connected to the SAN have access to storage devices like tape libraries and disk arrays available on the SAN servers as though it is local storage.
