Shared storage

Shared storage definition

Shared storage is a centralized storage system that is accessible to and can be simultaneously used by multiple users and devices. Shared storage solutions allow users or applications to access the data without creating and managing multiple copies, making it easier to collaborate.

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.
