摘要： A storage system 103 carries out first and second de-duplication processes in response to receiving a write request from a client. First, a determination is made as to whether a write target data item overlaps with any of the stored data items of a part of a stored data item group, which is a user data item group stored in a storage device 209, and if so, the write target data item is prevented from being stored in the storage device. Second, a determination is made as to whether a target stored data item, which is not finished being evaluated as to whether it overlaps with the stored data item in the first de-duplication process, overlaps with another stored data item, and if so, the target stored data item or the same data item overlapping with the target stored data item is deleted from the storage device 209.

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： 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： Decrease in the write speed is prevented even when overwriting the entire file. When a NAS apparatus receives a file size change request from a computer as an access request source for changing the size of a file, the NAS apparatus creates a new file related to the file in a file system with a processing performance that is higher than a file system containing the file as an entity of that file, associates the new file and the foregoing file, deletes the file on the condition that the new file and the file has been associated, and executes data write processing of writing data into the new file on the condition of subsequently receiving a data write request from the access request source for writing data into the file.
摘要翻译：即使覆盖整个文件，防止写入速度降低。当NAS装置从计算机接收到文件大小改变请求作为用于改变文件大小的访问请求源时，NAS装置在文件系统中创建与该文件相关的新文件，该文件系统的处理性能高于文件系统将文件作为该文件的实体，将新文件和上述文件相关联，在新文件和文件已关联的条件下删除文件，并执行将数据写入新文件的数据写入处理在随后从访问请求源接收到用于将数据写入文件的数据写入请求的条件下。
