    摘要: A unified storage system for executing a variety of types of storage control software using a single standardized hardware platform includes multiple storage control modules connected to storage devices for storing data related to input/output (I/O) operations. A first type of storage control software is initially installed and executed on a first storage control module for processing a first type of I/O operations. A management module replaces the first type of storage control software by installing a second type of storage control software onto the first storage control module. When the second type of storage control software is installed and executed, the first storage control module processes a second type of I/O operation, different from the first type of I/O operation. Control of volumes originally accessed by the first storage control module may be transferred to a second storage control module having the first type of storage control software installed.

    摘要: Embodiments of the invention provide a method and apparatus for storage subsystem migration without re-configuration of the I/O path. In one embodiment, a computer system comprises a first storage subsystem, a second storage subsystem, and a computer device connected via a network. The first storage subsystem has a first port name for a first port through which a first volume in the first storage subsystem has I/O connection with the computer device. The second storage subsystem defines a first virtual volume which is associated with the first volume, and a first virtual port having a first virtual port name that is identical to the first port name. After activation of the first virtual port, the computer device switches I/O connection for the first volume from the first storage subsystem to the second storage subsystem via the network using the first virtual port name on the second storage subsystem.

    摘要: Backup and restore operations are made possible in a storage system that has dynamic chunk allocation (DCA) capability. In a DCA storage system, a chunk of physical storage area is not allocated to a segment of a volume until a write command is received targeting the segment of the volume. During a restore operation of the volume in the DCA storage system, the wasting of storage capacity when a backup image of the volume is restored is mitigated by preventing allocation of physical storage areas to segments of restore data that are only void data.

    摘要: Information about management of virtualization (i.e. mapping between physical area/data/objects and logical area/data/objects) is provided by a storage system to a backup appliance (or common computer) that performs backup and restore of data. The backup appliance uses the information to recognize the mapping and to perform backup and restore process based on the mapping. Therefore the backup appliance handles only physical (really existing) area/data/objects to perform backup and restore rather than virtual ones. This realizes reducing the amount of data to be transferred and backed up, thus the problems mentioned above are solved.
