A virtual machine uses a virtual disk to store its operating system, program files, and other data associated with its activities. A virtual disk is a large physical file, or a set of files, that can be copied, moved, archived, and backed up.
To store virtual disk files and manipulate the files, a host requires dedicated storage space. ESXi storage is storage space on a variety of physical storage systems, local or networked, that a host uses to store virtual machine disks.
