    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： In order to provide HSM that can effectively use the storage capacity of an upper Tier in an HSM system, a lower Tier of the HSM system detects a group of files having the same data content from a plurality of files stored in the lower Tier, and keeps at least one of the real data of the group of files having the same data content while deleting the rest of the data. The upper Tier receives the process result from the lower Tier. Then, in response to a read request from the host computer that specifies a file included in the group of files and transferred to the upper Tier from the lower Tier, the upper Tier identifies the at least one of the data that is kept and corresponding to the specified file, and responds to the host computer.
