2 . Confirm that the correct server and storage pool is selected in the Storage Pool
selection page of the wizard, and click Next.
3 . Give a name and optional description for the new virtual disk, and then click Next.
4 . Select the storage layout. The options are Simple (no data redundancy and data
striped over many disks), Mirrored (data duplicated to additional disks), and Parity
(spreads data over multiple disks like Simple but adds parity data so that in the
event of a disk loss, no data is lost). Prior to Storage Spaces, these layouts would
have been referred to as RAID-0, RAID-1, and RAID-5, respectively, but that
nomenclature is not used with Storage Spaces layouts because of differences in
implementation.
Make the selection and click Next, as shown in Figure 4.3. A three-way mirror is
possible in Windows Server 2012 and beyond, but it must be configured using
PowerShell instead of the graphical interface.
5 . Choose a provisioning type of Thin or Fixed, and click Next.
6 . Specify a size. Remember, if you selected Thin, you can now select a size larger
than the physical free space available. Click Next.
7 . A confirmation of options is displayed. Confirm them, and click Create.

Once the virtual disk is created, it will be available within Server Manager and the
Disk Management MMC to create volumes and be formatted with a filesystem. The
amount of space used from a pool can be seen in Server Manager or, if you’re using a
