1. A virtualization system, comprising:
- a first virtualization device having a first virtual volume related to a first logical volume of a first storage system, said first storage system having a first storage controller, a plurality of first disk drives and said first logical volume related to at least one of said first disk drives; and
a second virtualization device having a second virtual volume related to a second logical volume of a second storage system, said second storage system having a second storage controller, a plurality of second disk drives and said second logical volume related to at least one of said second disk drives, wherein the first and second virtualization devices are configured to copy data between the first and second virtual volumes.

Abstract
A first storage control device is provided with a virtual LU for showing a logical volume possessed by a second storage control device as if it were its own volume. When data processing requested from a host device is, for example, a specific processing of large load (such as direct backup, logical volume copy, and so on), whether or not the requested processing can be executed by the second storage control device is judged. When it is executable, a command is transmitted to the second storage control device to make it take over the processing.

10. A virtualization method, comprising the steps of:
-
providing a first virtualization device having a first virtual volume related to a first logical volume of a first storage method, said first storage system having a first storage controller, a plurality of first disk drives and said first logical volume related to at least one of said first disk drives;
providing a second virtualization device having a second virtual volume related to a second logical volume of a second storage system, said second storage method having a second storage controller, a plurality of second disk drives and said second logical volume related to at least one of said second disk drives; and
copying data between the first and second virtualization devices so as to effect copying of data between the first and second virtual volumes. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A virtualization method for a system comprising a first virtualization device having a first virtual volume related to a first logical volume of a first storage method, said first storage method having a first storage controller and a plurality of first disk drives, and a second virtualization device having a second virtual volume related to a second logical volume of a second storage method, said second storage method having a second storage controller and a plurality of second disk drives, the method comprising the steps of:
-
relating said first logical volume related to at least one of said first disk drives;
relating said second logical volume related to at least one of said second disk drives; and
copying data between the first and second virtual volumes via copying if data between the first and second virtualization devices. - View Dependent Claims (20)
