Which virtualization enables the logical partitioning of a server's operating system environment by virtualization of storage devices?

• A. Server Virtualization
• B. Storage Device Virtualization
• C. Storage Virtualization
• D. File System Virtualization

Answer: (B)

The idea being tested is how storage can be abstracted to create dedicated, logical storage units that the server’s operating system treats as separate disks. When storage devices are virtualized, physical disks are presented as virtual disks or LUNs that can be allocated to different OS environments on the same server. This decoupling of the OS view from the actual hardware makes it possible to partition the server’s OS environment into distinct, independent storage spaces without changing the physical disks. That precise capability—creating logical OS partitions through virtualization of the storage devices—is the essence of virtualization of storage devices. Server virtualization focuses on running multiple OS instances on one physical host via a hypervisor, which handles compute isolation rather than creating OS partitions through storage. Storage virtualization, while related, generally describes pooling and managing storage resources across devices rather than the act of presenting individual virtual storage units to carve up the OS environment. File system virtualization deals with presenting a unified or abstracted view of files and directories, not with partitioning the OS environment itself.
