20080209041 | VOLUME ALLOCATION METHOD - A management device selects a storage device having a plenty of unallocated storage regions, selects a target using a port having a small allocation quantity from the storage device targets, and allocates the target, an initiator, and a storage region. When the number of targets and the allocated storage regions prepared by the storage device is within a predetermined number, the storage device manages the storage device as an allocation candidate. When the predetermined number is exceeded, the exceeding one is excluded from the allocation candidate. When the number of storage devices excluded from the allocation candidate has reached a certain number, the management device manages a new storage device and a new storage region as an allocation candidate. | 08-28-2008 |
20080215767 | Storage usage exclusive method - In an environment where there is a possibility that the user connects from a plurality of blade PCs to the storage, the present invention prevents the data destruction by realizing the exclusive control of the storage device. The storage connection from a blade PC which was possible to connect until now is made to be impossible by that the management server newly generates and sets to the storage device the connection information between the storage device which the blade PC keeps. Further, by sending the newly generated connection information to the other blade PC the connection from that blade PC becomes possible. | 09-04-2008 |
20100083015 | VIRTUAL PC MANAGEMENT METHOD, VIRTUAL PC MANAGEMENT SYSTEM, AND VIRTUAL PC MANAGEMENT PROGRAM - The virtual PC management system includes: a unit which acquires a power on/off state of a virtual machine from a computer via the network and stores it in a storage; a unit which acquires a power on/off state of a computer from the computer via the network and stores it into the storage; a unit which receives a start-of-use request for a virtual machine from the client machine and searches stored data of the storage unit for a computer which is in a power-on state and to which a virtual machine is not allocated, as an allocation candidate; a unit which allocates the virtual machine in accordance with the start-of-use request to the computer of the allocation candidate; and a unit which notifies, via the network, the computer of the allocation candidate of an instruction to turn on the power of the virtual machine. | 04-01-2010 |
20110061049 | Storage system, and remote copy control method therefor - A storage system includes an information apparatus in which a virtualization mechanism is implemented to build a virtual machine, a storage apparatus which is coupled to the information apparatus, which includes a first logical volume proving a storage area to be used by the virtual machine, and which includes a virtual disk area and a virtual disk management area on the first logical volume, the virtual disk area used by the virtual machine to store data, the virtual disk management area storing management data for managing the virtual disk area; and a management computer which is coupled to the information apparatus and the storage apparatus, and which includes a remote copy controller configured to copy the virtual disk area and the virtual disk management area on the first logical volume of the storage apparatus to a storage area on a second logical volume included in a second storage device coupled to the storage apparatus. The remote copy controller determines whether, on the second logical volume, there is the virtual disk management area used by the virtual machine. When determining that there is not, the remote copy controller transmits, to the storage apparatus, an instruction to copy the virtual disk management area and the virtual disk area to the second logical volume. | 03-10-2011 |
