Create a
Spanned Volume
Applies To: Windows 7, Windows Server 2008 R2
A spanned volume is a dynamic volume consisting of
disk space on more than one physical disk. If a simple volume is not a system volume
or boot volume, you can extend it across additional disks to create a spanned
volume, or you can create a spanned volume in unallocated space on a dynamic
disk.
You need at least two dynamic disks in addition to
the startup disk to create a spanned volume. You can extend a spanned volume
onto a maximum of 32 dynamic disks.
Spanned volumes are not fault tolerant.
Backup Operator or Administrator is the minimum membership required to complete the
