What is the purpose of Storage Virtualization?

The purpose of storage virtualization is to combine multiple physical storage devices into a single virtual storage device, simplifying management, enhancing resource utilization, and providing flexibility in how storage resources are allocated and accessed. By creating a virtualized storage environment, it abstracts the details of the underlying hardware, which means users can manage storage resources without needing to understand the complexities of the physical devices involved. This approach allows for improved efficiency, easier scalability, and better performance due to the dynamic allocation of storage space based on current needs.

Other options focus on different aspects of IT infrastructure or security rather than the core function of storage virtualization itself. For instance, while isolating network devices is essential for network management and security, it does not pertain to the way storage is managed or utilized. Preventing data breaches in cloud services relates to cybersecurity measures rather than the aggregation of storage resources. Backing up data from multiple sources is a crucial function of data management, but it does not directly relate to the virtualization of storage, which aims more at integration and abstraction than at backup processes.
