One of the courses I teach is the Microsoft Windows 2012 Installing and Configuring course, the Microsoft designation is the 20410B

In the presentation, we look at configuring Mount Points and Links.

Mount Points

 

Mount points are used in Windows operating systems to make a portion of a disk or the entire disk useable by the operating system. Most commonly, mount points are associated with drive-letter mappings so that the operating system can gain access to the disk through the drive letter.

 

Since the Windows 2000 Server was first introduced, you have been able to enable volume mount points, which you can then use to mount a hard disk to an empty folder that is located on another drive. For example, if you add a new hard disk to a server, rather than mounting the drive using a drive letter, you can assign a folder name such as C:\datadrive to the drive. When you do this, any time you access the C:\datadrive folder, you are actually accessing the new hard disk.

 

Volume mount points can be useful in the following scenarios:

 

If you are running out of drive space on a server and you want to add disk space without modifying the folder structure. You can add the hard disk, and configure a folder to point to the hard disk.

 

If you are running out of available letters to assign to partitions or volumes. If you have several hard disks that are attached to the server, you may run out of available letters in the alphabet to which to assign drive letters. By using a volume mount point, you can add additional partitions or volumes without using more drive letters.

 

If you need to separate disk input/output (I/O) within a folder structure. For example, if you are using an application that requires a specific file structure, but which uses the hard disks extensively, you can separate the disk I/O by creating a volume mount point within the folder structure.

 

Links

 

A link is a special type of file that contains a reference to another file or directory in the form of an absolute or relative path. Windows supports the following two types of links:

 

A symbolic file link (also known as a soft link)

A symbolic directory link (also known as a directory junction)

 

A link that is stored on a server share could refer back to a directory on a client that is not actually accessible from the server where the link is stored. Because the link processing is done from the client, the link would work correctly to access the client, even though the server cannot access the client.

Links operate transparently. Applications that read or write to files that are named by a link behave as if they are operating directly on the target file. For example, you can use a symbolic link to link to a Hyper-

V parent virtual hard disk file (.vhd) from another location. Hyper-V uses the link to work with the parent virtual hard disk (VHD) as it would the original file. The benefit of using symbolic links is that you do not need to modify the properties of your differencing VHD.

 

Links are sometimes easier to manage than mount points. Mount points force you to place the files on the root of the volumes, whereas with links you can be more flexible with where you save files.

 

You can create links by using the mklink.exe command-line tool.
