A virtual disk contains two components: the virtual disk itself as it appears in a guest domain, and the virtual disk back end, which is where data is stored and where virtual I/O ends up. The virtual disk back end is exported from a service domain by the virtual disk server (vds) driver. The vds driver communicates with the virtual disk client (vdc) driver in the guest domain through the hypervisor using a logical domain channel (LDC). Finally, a virtual disk appears as /dev/[r]dsk/cXdYsZ devices in the guest domain.
The virtual disk back end can be physical or logical. Physical devices can include the following:
Physical disk or disk logical unit number (LUN)
Physical disk slice
Logical devices can be any of the following:
File on a file system, such as ZFS or UFS
Logical volume from a volume manager, such as ZFS, VxVM, or Solaris Volume Manager
Any disk pseudo device accessible from the service domain
