Definition
Shared storage refers to a system where multiple computing devices or users can access the same data and resources from a central location. This is typically achieved through network attached storage (NAS) or storage area networks (SAN) that present storage volumes to servers or clients. Shared storage is crucial for enabling collaboration, efficient data management, and high availability in modern IT environments. For instance, a team of developers might use shared storage to access a common code repository, preventing version conflicts and ensuring everyone works with the latest files. Unlike direct attached storage (DAS) where a drive is exclusively connected to a single computer, shared storage allows concurrent access from many. Concepts of shared storage are frequently assessed in cybersecurity certifications like Security+ and CySA+ as well as cloud infrastructure exams such as AWS Certified Solutions Architect.
