The goal of the logical disk is to provide computer software with what seems a contiguous storage area, sparing them the burden of dealing with the intricacies of storing files on multiple physical units.
For example, Windows NT can create several partitions on a hard disk drive, each of which a separate volume with its own file system.
As such logical disks or vdisks allow computer programs to access files stored on a SAN.
In case of the latter, specialized management, maintenance and diagnostics software dedicated to that specific RAID may run on the operating system.
[2] Today, the rationale for the logical disk approach starts to be questioned[3] and solutions that offer more flexibility and better abstraction are increasingly needed.
