Storage Array Logical Drives versus Windows Volumes

There is, conceptually, a big difference between a logical drive created on the storage
array and a volume created within Windows. Windows volumes are created using
some or all of the space taken up by a logical drive. This can be a problem if using VSS
and an Overland storage array together:
• A logical drive of 200GB is created and mapped on the enclosure.
• The user now creates two volumes with Windows Disk Manager, each of 100GB.
These are assigned the drive letters D: and E:.
