Storage system comprising multiple storage apparatuses with both storage virtualization function and capacity virtualization function
Abstract:
A storage system includes a first storage apparatus and a second storage apparatus. The first storage apparatus includes a capacity pool that is partitioned into multiple pool pages and includes a storage area of an external logical volume provided by at least one storage apparatus. The second storage apparatus provides first virtual volume which is a virtual logical volume comprising multiple first virtual areas. In a case of receiving a write request from the computer to a virtual area in the first virtual volume to which a page is not allocated, an unallocated pool page of the external logical volume is allocated to the virtual area. An authority to allocate the unallocated pool page of the external logical volume is assigned to the first storage apparatus.
