摘要： There is a journal area and one or more logical volumes comprising a first logical volume. The journal area is a storage area in which is stored a journal data element, which is a data element that is stored in any storage area of a plurality of storage areas configuring a logical volume, or a data element that is written to the storage area. A controller has a size receiver that receives a write unit size, which is the size of a write data element received from a computer, and a size setting unit that sets the received write unit size in a memory for one or more logical volumes. The size of a journal data element stored in a journal area based on the set write unit size is the write unit size.

摘要： A virtual storage system is equipped with a plurality of storage systems and a virtualization device for virtualizing the plurality of storage systems logically into a single storage resource provided to a host computer. When one of the storage systems receives a command from the host computer, in the event that the storage system itself is not in possession of a function corresponding to the command, the storage system retrieves a storage system in possession of a function corresponding to the command and transfers this command to the storage system in possession of the function corresponding to the command.

摘要： If an I/O load on a first virtual storage area falls below a first threshold, a controller copies data in a first storage area, which is allocated to the first virtual storage area, to a third storage area in a second tier storage area, and allocates the third storage area instead of the first storage area to the first virtual storage area. If an I/O load on a second virtual storage area exceeds a second threshold which is greater than said first threshold, the controller copies data in a second storage area, which is allocated to the second virtual storage area, to a fourth storage area in a first tier storage area, and allocates the fourth storage area instead of the second storage area to the second virtual storage area.
