What does storage virtualization achieve?

Storage virtualization achieves the representation of multiple physical storage devices as a single storage device. This abstraction layer simplifies management by allowing administrators to treat different types of storage (such as hard drives, SSDs, and SANs) as one cohesive unit. By doing this, it enables better utilization of resources, improved performance management, and easier allocation and scaling of storage. Additionally, storage virtualization can enhance flexibility, allowing for dynamic provisioning and easier allocation of storage space based on demand. It does not directly pertain to specific improvements in network security, data backup processes, or increased physical storage space, but rather focuses on the management and abstraction of existing storage resources.
