Computing system having a controller for controlling allocation of a storage area of a logical volume in a pool to a virtual volume and controlling methods for the same
Abstract:
Provided is a computer system capable equalizing the storage capacity immediately and reliably to multiple real logical areas dynamically providing storage capacity to virtual logical areas.This computer system is characterized by, during the course of executing an operation of dynamically allocating a storage area to a virtual volume in response to an access from a host system, detecting an occasion where balance of a storage capacity among a plurality of logical areas is disrupted; and subsequently moving the storage area among a plurality of logical areas to maintain balance of the storage capacity.
