What does storage refer to in the context of virtual disk configuration?

In the context of virtual disk configuration, storage specifically refers to the space allocated for a specific virtual machine (VM). This storage is essential because it determines how much data the VM can store and operate with, including the operating system, applications, and user data.

When configuring a virtual disk, administrators must carefully consider the allocated storage to ensure that the VM has enough space for its intended use. This allocated space is abstracted from the physical storage of the host server, meaning that a single physical disk can support multiple VMs with different storage configurations. Thus, the concept of storage here is fundamentally about the specific allocation for the virtual environment rather than the physical characteristics of the host system or backup resources.
