Appendix B

Creating Virtual Disks: Future Expansion

When creating virtual disks, consider whether or not the virtual disk capacity

needs to be expanded in the future.
For a Microsoft Windows

operating system, format the virtual disks with New

Technology File System (NTFS). Microsoft Corporation provides a utility

(diskpart.exe) that can dynamically extend an NTFS file system onto any

unused adjacent space.
Note also that using a single partition per virtual disk makes expansion much

easier.

NOTE:

The diskpart.exe utility version depends on which version of the Windows

operating system is running.

NOTE:

The diskpart.exe utility can be found on the CD for some versions of

Windows operating systems, or on the Microsoft Corporation website

(microsoft.com) for other versions. Use the correct version for your operating

system.
