摘要： An information processing system retains one or more files utilized by an external apparatus, each of which is made up of a plurality of chunks, in a manner that the chunks making up each of the files are distributed. The information processing system includes a plurality of chunk servers, each storing chunks, and one master server communicatively coupled thereto. The master server retains a file name of a file, chunk IDs indicating chunks making up the file, and chunk IDs indicating chunk servers storing the chunks. When a snapshot taking request for a file is received, the master server identifies chunks included in the file from the file name and the chunk IDs to instruct the chunk servers having these chunks to take a differential snapshot of each of the chunks with the use of a differential snapshot function included in a local file system of each of the chunk servers.

摘要： Predicting whether a file migration will be executed successfully or not. A file storage apparatus in a high-order tier generates a migration task list that records scheduled time periods of migration execution and a total file size of files which are targets to be migrated, and transfers the generated migration task list to a file storage apparatus in a low-order tier; and the file storage apparatus in the low-order tier generates, based on the migration task list, a migration overlap table that records, for each unit time, whether the execution of a migration is scheduled or not, and a remaining file size table that records a predicted value of a data transfer amount for each unit time and a predicted value of a remaining file size for each unit time; and if the predicted value in the last scheduled time period, from among the predicted value of the remaining file size for each unit time which is recorded in the remaining file size table, is equal to or less than 0, it is predicted that the migration will be executed successfully; and if the predicted value in the last scheduled time period is more than 0, it is predicted that the execution of the migration will fail.

摘要： A file management sub-system executes file migration without causing an unintended drop in the response time or the like. When a management computer issues a file migration direction, a file storage apparatus notifies client computer associated with a migration target file that file migration is scheduled. When postponement or suspension of file migration is requested by the client computer, the file migration is postponed or suspended.

摘要： A new storage tier is added to a plurality of storage tiers configured in storage areas of a plurality of types of storage devices, whose processing performance is different from each other, without changing its operation form. If a new Tier3 constituting a file system FS4 is added between Tier2 and Tier3, a file server adds a registered generation 1 to a tier number change management table, sets Tier3 as the added file system FS4 in the registered generation 1, manages Tier4 as a file system FS5, which has been changed from the former Tier3, adds a policy corresponding to a policy number 1005 to a migration policy management table, updates only the registered generation from 0 to 1 for policy numbers 1002, 1005, and manages the migration policy management table.

摘要： Time required for a file server to determine files to be migrated from a first storage region to a second storage region is reduced. A file service system coupled to the storage system for providing a first storage region and a second storage region stores identifiers of files that have been accessed by a client, in accessed file identifier information and determines the files to be migrated from the first storage region to the second storage region based on metadata of the files stored in the first storage region and the accessed file identifier information.

摘要： A storage system providing a storage area to an external device comprises a plurality of storage apparatuses and of different performance capabilities, and a storage controller. The storage controller holds storage cost coefficients 3202 of the respective storage apparatuses and user cost allocation information 3302 for each user using the storage system from the external device and user cost distribution information 3402 that defines, for each user, proportions of an available space amount distributed to the storage apparatuses. The storage controller calculates an ideal utilization 3502 for each user, from the storage cost coefficients 3202 and the user cost distribution information 3402, and allocates, for each user, the ideal utilization 3502 to each of the storage apparatuses and in the order of the performance capabilities from highest to lowest.
