Windows 2000 - volume-mount points to add storage

Because Microsoft's NT 2000 operating system is volume oriented it contains a number of features that make it easier to manage sophisticated storage architectures. One key feature is the volume mount point. Like a number of the new storage features in Windows 2000, the capabilities offered by volume mount points are familiar with administrators of enterprise-level operating systems like UNIX (even if the terminology isn't) but they have been lacking in Windows.
Volume mount points are file-system objects within the operating system's name space that represent dynamic storage structures. One of their most important features is that they can be changed without having to add or remove drive letters. By using volume mount points you can mount or unmount entire data structures, add or remove entire physical disks or collections of physical disks or even attach the same volume at several different points in the file system.
Multiple attachments of the same volume (under different names) are convenient, but they do carry a potential problem. There is nothing in the design of Windows 2000 that prevents an administrator from mounting a volume underneath itself. If you try to mount a volume within itself, you will create an endless loop if an application tries to do an enumeration of that name space.
For more information on mount points and how to use them in Windows 2000, see the Microsoft web page.
