  • Patent number: 8341365
    Abstract: Systems for backing up the data of an IT system by utilizing server or storage virtualization technology to create and move logical IT infrastructures dynamically. A virtualized IT system provides a server resource pool and a storage resource pool composed from multiple physical devices either within a datacenter or a globally located plurality of datacenters. The virtual server and the storage volume provisioned from those pools will be paired to form the virtual infrastructure. In other words, the virtual infrastructure becomes a logical IT environment build with the required computing and storage resources needed in order to execute specific applications. The virtual infrastructure can also be migrated within/among datacenter sites.

  • Patent number: 8281301
    Abstract: Providing a volume to a host computer by a storage system is automated for ensuring that an appropriate version of a storage control software is installed on a storage control module of the storage system that manages access of the host computer to the volume. When the volume on the storage system is allocated for use by the computer, a control module on the storage system is designated for managing the access to the volume. An operating system to be used on the computer when accessing the volume is determined, and a compatible version of the storage control software is uploaded and installed on the storage control module. Multiple storage control modules may be provided on the storage system and virtual machines may be used on the storage control modules for enabling simultaneous operation of more than one version of the storage control software on each storage control module.

  • Patent number: 8281105
    Abstract: A storage system comprises a storage apparatus which includes a processor, storage disks, and a memory storing a page mapping table, a page mapping program, and a page-filename mapping program. A file system manages a file tree of files with filenames. The page mapping table specifies a relationship between data volumes in the storage apparatus and the storage disks and the file system, the data volumes each including pages, each page including segments, each segment including sectors. The file tree has for each storage apparatus a hierarchy of directories and files based on relationships among the data volumes, the pages, and the segments. The page mapping program and the page-filename mapping program are executable by the processor to specify, by page, a location of data contained in the I/O request by referring to the page mapping table and the file tree.

  • Publication number: 20120117345
    Abstract: 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.

  • Patent number: 8156293
    Abstract: 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.
