About spanned volumes

Last published : Apr 02, 2026
After you convert a basic disk to a dynamic disk, you can create spanned volumes.
Before you create spanned volumes, consider the following:
  • You can create spanned volumes on dynamic disks only.
  • You need at least two dynamic disks to create a spanned volume.
  • You can extend a spanned volume onto a maximum of 32 dynamic disks.
  • You cannot mirror or stripe a spanned volume.
  • Spanned volumes are not fault tolerant.
