Microsoft dynamic disks use multiple hard disks, which can contain many dynamic volumes, to manage data. They enable you to create volumes that span multiple disks and to create fault-tolerant volumes. All volumes on dynamic disks are known as dynamic volumes. Dynamic disks offer greater flexibility for volume management because they use a database to track information about dynamic volumes on the disk. Dynamic disks and volumes rely on the Logical Disk Manager (LDM) and Virtual Disk Service (VDS) for management.

When recovering virtual machines in a VPG, VHDX disks are always recovered in the recovery site with dynamic disks. VHD disks are recovered in the recovery site by default with the same configuration as in the protected site.
