摘要： 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.

摘要： Embodiments of the invention provide object-based tier management to improve the allocation of objects to different media of different speeds based on access characteristics such as access frequency. One embodiment is directed to a method of managing object-based data in an information system which includes an application server and a storage system. The method comprises receiving a write command including a first data to be written into a virtual volume; identifying an object to which the first data corresponds; checking if a second data corresponding to the object has been stored in the virtual volume; if the second data has been stored in a page of the virtual volume, checking if the page which stores the second data has a vacancy area; and if the page has a vacancy area, writing the first data in the page which stores the second data.

摘要： In an information system which includes a local site including a cache file server coupled with a host computer, and a remote site including a remote file server coupled with a surrogate processing computer, a method determines whether each of one or more files of data for a data processing request is cached or not. If yes, the method executes data processing for each cached file to produce results in local site. If no, the method includes creating a file list of files to be processed in remote site; sending the file list and processing program to the surrogate computer; if the processing is sufficiently effective to be done by the surrogate computer, receiving results of the processing executed in remote site, and, if not, then receiving an unprocessed file list from remote site and executing data processing in local site and receiving any results already executed in remote site.

摘要： A method switches file server from old file server to new file server which are coupled via a backend network and provides data synchronization. The old file server and new file server are coupled with one or more host computers via a frontend network to direct input/output (I/O) requests from the one or more host computers. The method comprises creating stub files in the new file server, the stub files including stub information indicating location of data in the old file server; switching I/O requests directed to old file server to I/O requests directed to the new file server; checking whether the new file server has any stub files; and, if the new file server has one or more stub files, recalling data corresponding to the one or more stub files from the old file server according to the stub information to replace the one or more stub files.
