摘要： A volume provider unit in a computer system that detects a logical block address of a read or write I/O accessing a logical volume of a storage device from a host. According to the logical block address fetched, a storage domain of the logical volume is dynamically expanded. Moreover, the storage domain of the logical volume is reduced or expanded according to an instruction of logical volume capacity reduction or expansion from a host commander part to a volume server.

摘要： Computerized information system and method having multiple virtual machines share common resources such as the system storage resources. The system contains a host computer executing multiple virtual machines, system resources organized into multiple resource groups, and a resource controller associating a resource group with a virtual machine executing on the host computer. When a state of the virtual machine changes, the resource controller releases the previously allocated resource group and when a request to execute another virtual machine is received, a new resource group is allocated to the host computer.

摘要： By incorporating a referral mechanism, a failover method and system for remotely mirrored clustered file servers enables a client computer to transparently access a remotely mirrored file system during a failover of a first NAS (network attached storage) storing the file system. The first NAS is clustered with a second NAS that takes over the IP address of the first NAS on failover. A mirroring relationship is established between the first NAS and a third NAS whereby a copy of the file system is replicated to the third NAS. A referral is created on the second NAS, such that an access attempt from the client computer for accessing the first file system that is directed to the second NAS following IP address takeover from the first NAS after failover is referred to the third NAS by the referral to enable the client computer to access the copy of the file system.

摘要： In the remote mirroring system of this invention, the primary system has the capability of treating the volume in the remote storage system as a virtual storage devices in the primary storage system. The primary storage system realizes remote mirroring between different storage systems by copying data from the primary volume to the virtual volume(s) defined in the primary storage system. This enables remote mirroring between storage systems produced by the different vendors.

摘要： An apparatus, system, and method enable access to a storage system by distinguishing SCSI Object-Based Storage Device Commands (OSD) commands from Fibre Channel (FC) SCSI commands on the same port and storage subsystem. The storage subsystem has the capability of identifying the storage protocol from a corresponding command, and processes the command accordingly for a storage device formatted for use with the respective storage protocol. This way, a storage subsystem can consolidate data from several dedicated command ports to a single physical port, while also enabling a single storage system to store and provide access to data in multiple different storage protocol formats.

摘要： A storage system including a storage controller is coupled to a host computer. When the host computer is connected, the controller deploys a set of virtual devices dedicated to the host computer, which typically cannot be accessed by other host computers. The storage controller includes a logical device manager that defines a group of logical devices from among disk drives in the storage system, and each logical device is assigned a storage area that includes at least a portion from a disk drive. A virtual device manager defines virtual devices from the group of logical devices, and maintains a record of the relationships among the logical devices and the virtual devices. When a request for a data operation is received by the storage system from a host which has not previously accessed the storage system, the virtual device manager defines a virtual device for access by that host and assigns a logical device to the virtual device.

摘要： Techniques to assure genuineness of data stored on a storage device are provided. The storage device includes a storage controller that conducts I/O operations and management operations. A description of management operations and corresponding timestamps are recorded to an operation log stored in a memory. The memory additionally stores an attribute for each storage volume of the storage device. Write access to each of the storage volumes is dependent on the attribute.

摘要： An object of remote copy can be specified in units of a file or a directory more detailed than in units of a volume. If a host computer issues a write request of a file to NASa, NASa references a source NAS of remote copy and a source directory of remote copy at each entry on a copy file table and determines whether the file to be written is an object of remote copy; if it is determined to be an object of remote copy, the file to be written is remotely copied to a target directory of remote copy of a target NAS thereof.
