Shared storage types
- Cloud storage. Cloud storage is hosted by a third-party provider and can be accessed by multiple users over the internet. It’s commonly used for collaboration, backup, and archiving.
- Network-attached storage (NAS). A file-level storage solution that connects to a network and provides shared access to folders and files. It’s widely used by small to medium-sized businesses.
- Storage area network (SAN). SAN is a block-level storage solution providing high-speed data transfers between servers and storage devices. Large enterprises use SAN systems because they deliver high performance and scalability.
- Distributed File System (DFS). DFS systems are high-level and allow users to access folders and files from multiple servers as if stored on one system. DFS provides a high level of scalability and is widely used by large enterprises.
How shared storage works
- Shared storage can be implemented in several ways but typically consists of a server or storage device that manages the storage capacity.
- Users, applications, or devices can access the shared storage directly over a local network, remotely over the internet, or through a storage management application.
- Before accessing the shared files, users must be authenticated according to the company’s security procedures and policies.
