| 20120011321 | METHOD AND SYSTEM OF COLLECTION PERFORMANCE DATA FOR STORAGE NETWORK - This invention provides a user or an operator with a management apparatus or method for displaying logical connection information between an interface connected to a computer and a switch and a storage system or a logical unit in the storage system in a virtual storage system, wherein the switch receives a first access request from said computer, converts said first access request to a second access request to one of said plural storage systems, and sends said second access request to one of said plural storage systems or one logical unit. | 01-12-2012 |
| 20120011315 | STORAGE SYSTEM - A RAID group is not configured from a plurality of storage devices. A storage area of a storage device is provided directly to a virtual volume instead of providing a logical volume inside the RAID group to the virtual volume. The storage system, upon receiving a write request with respect to a virtual storage area, first, specifies a data redundancy configuration (the number of data partitions and the number of created parities) and a RAID level set to a virtual volume including this virtual storage area. From among storage devices selected in accordance with specified RAID level and redundancy configuration for this virtual storage area, a storage area is selected that is not allocated to any virtual storage area, and allocates this storage area to this virtual storage area. The storage system partitions the data and writes this data together with the parity to this allocated storage area. | 01-12-2012 |
| 20120011311 | STORAGE SYSTEM FOR CONTROLLING ASSIGNMENT OF STORAGE AREA TO VIRTUAL VOLUME STORING SPECIFIC PATTERN DATA - A storage system comprises a storage medium including a plurality of physical storage areas. The storage system controls a host computer to recognize a logical volume having a plurality of virtual storage areas, reads the data from the physical storage area assigned to the virtual storage area of the logical volume, determines whether or not the read data includes only the specific pattern data, and cancels the assignment of the physical storage area to the virtual storage area if the read data includes only the specific pattern data. | 01-12-2012 |
