摘要： Disclosed is a storage system having storage devices from which storage areas are specified. Virtualization apparatuses allocate the storage areas as virtual volumes and processes I/O requests with respect to the virtual volumes. A controller is operable to change the allocation of storage areas to the virtual volumes. The controller is configured to send a request to some of the virtualization apparatuses to temporarily suspend processing of their I/O. When a virtualization apparatus receives such a request, it completes its pending I/O and temporarily suspends subsequent I/O requests, and sends a completion report to the controller. The controller then changes the allocation of storage areas to the virtual volumes.

摘要： In a system comprising host computers and storage devices, storage regions maintained by storage devices are provided as virtualized volumes to the host computers by a virtualization function. In the case of allocating a vacant storage region from storage regions of a storage device to a virtualized volume, the virtualization function repeats to acquire and allocate a storage region from the vacant storage region until a remaining size within a required size becomes smaller than a maximum region size and, below the maximum region size, acquires and allocates a storage region, whose size is the smallest power of two not smaller than the remaining size, from the vacant storage region. If the vacant storage region includes a plurality of continuous vacant regions, the virtualization function selects the largest continuous vacant region for allocation.

摘要： In a system where a storage device is coupled to a computer, a storage area in the storage device is efficiently allocated to the computer. The system comprises a virtualization apparatus to be coupled to the computer and a plurality of storage devices to be coupled to the virtualization apparatus. The virtualization apparatus, responding to a request from the computer, issues a notice to the effect that a predetermined size of virtual volume has been allocated to the computer. The virtualization apparatus, upon receiving an access request from the computer to the virtual volume, allocates storage areas existing in a plurality of storage devices to the virtual volume, converts the access request received from the computer to an access request addressed to a storage device having the storage devices allocated to the virtual volume, and transmits the converted access request to the storage device.

摘要： For betterment, by putting a virtual storage device into a suspend mode, physical resources are turned OFF on a virtual storage device basis. Moreover, control information and volume data of the virtual storage device are stored in any external volume, for example, and the resources that have been used by the virtual storage device are deallocated. At the time of resumption of operation, using any resources not in use, the virtual storage device is restored based on the control information in storage. When a change is made to a WWN on the side of a host, the storage device receives a WWN change notification from a management server, and makes settings again to a WWN table, thereby making it accessible from the host.
摘要翻译：为了改善，通过将虚拟存储设备置于挂起模式，物理资源在虚拟存储设备的基础上被关闭。此外，虚拟存储装置的控制信息和卷数据被存储在例如任何外部卷中，并且由虚拟存储装置使用的资源被解除分配。在恢复运行时，使用任何未使用的资源，根据存储中的控制信息恢复虚拟存储设备。当对主机侧的WWN进行了更改时，存储装置从管理服务器接收到WWN变更通知，再次对WWN表进行设定，从而能够从主机访问。
