20080235448 | Storage apparatus and storage area arrangement method - This storage apparatus for providing a dynamically expandable virtual volume to a host system to access the virtual volume comprises an allocation unit for configuring a group with a plurality of disks for providing a storage area to be allocated to the virtual volume, and allocating the storage area respectively from a plurality of the groups to the virtual volume; and a storage area arrangement unit for rearranging the storage area in each of the groups being used by the virtual volume to become optimal among each of the groups based on external operation. | 09-25-2008 |
20090138672 | Storage controller and storage controller control method - A storage controller of the present invention can input and output data even when the track size, which is the host management unit, is not consistent with the block size of the storage device. A boundary correction unit adds gap data corresponding to a gap size to data in a buffer memory so that the boundary of the track and boundary of the block inside the storage device match. A guarantee code is added to each logical block received from the host, and these guarantee code-appended blocks are stored in a cache memory. By providing a gap in the storage device every 116 extended logical blocks, the start position of the lead block of a track matches up with the start position of the logical blocks of the storage device. | 05-28-2009 |
20100131805 | STORAGE CONTROLLER AND METHOD FOR CONTROLLING THE SAME - A storage controller of the present invention detects error with relative ease when reading out data from a storage apparatus. An address data appending device appends address data to each of logical blocks with respect to the data received from a host. A device communication control device determines a divisional position in every data with a size of a predetermined number of blocks, counterchanges the data in anterior and posterior parts around the divisional position, and stores the data in the storage apparatus. When reading the data from the storage apparatus, an address data checking device determines whether or not the value of the address data appended to the block read out and an expected value of the address data calculated based on the divisional position match with each other. If the both values match with each other, the data is sent to the cache memory. If the both values fail to match each other, an error is detected. | 05-27-2010 |
20100138624 | Storage Controller And Storage Control Method - A storage control technique with which, even if not data, but only its management information is deleted, a host system can recognize storage areas storing unnecessary data and so use them effectively.
