Detailed explanation-1: -In computer science, storage virtualization is “the process of presenting a logical view of the physical storage resources to” a host computer system, “treating all storage media (hard disk, optical disk, tape, etc.) in the enterprise as a single pool of storage."
Detailed explanation-2: -What is a virtual hard disk (VHD)? A virtual hard disk (VHD) is a disk image file format for storing the entire contents of a computer’s hard drive. The disk image, sometimes called a virtual machine (VM), replicates an existing hard drive, including all data and structural elements.
Detailed explanation-3: -The virtual drive can be used to install virtual machine guest operating systems, applications and data. Virtual drive capacity depends on the base requirement and the underlying physical drive capacity. In storage virtualization, a virtual drive is a logically isolated storage drive on top of a storage area network.
Detailed explanation-4: -Storage virtualization (also sometimes called software-defined storage or a virtual SAN) is the pooling of multiple physical storage arrays from SANs and making them appear as a single virtual storage device.
Detailed explanation-5: -The virtual hard disk (VHD) format is a block-based format that stores the contents of a virtual machine. VHDs use the *. vhd file that simulates the properties of a physical hard drive. Virtual hard disks can be created during the VM creation using Hyper-V Manager.
