摘要： An application programming interface (API), functioning as an interface between a storage controller and an owning application, is used to migrate, from a specified source LUN to a specified target LUN, at least one specified sub-LUN data chunk, the at least one specified sub-LUN data chunk having a predefined chunk size fixed by the storage controller. A specified total migration size is incrementally reduced by each completed migration of the at least one specified sub-LUN data chunk until the total migration size is zero and the migration is completed.

摘要： A source code-based specification is implemented for use as an interface between a storage controller and an owning application to migrate a specified size of data from physical storage behind the LUN to a new physical location.

摘要翻译： 实现基于源代码的规范用作存储控制器和拥有应用程序之间的接口，以将指定大小的数据从LUN后面的物理存储迁移到新的物理位置。

摘要： A method includes receiving a request to save a first file as immutable. The method also includes searching for a second file that is saved and is redundant to the first file. The method further includes determining the second file is one of mutable and immutable. When the second file is mutable, the method includes saving the first file as a master copy, and replacing the second file with a soft link pointing to the master copy. When the second file is immutable, the method includes determining which of the first and second files has a later expiration date and an earlier expiration date, saving the one of the first and second files with the later expiration date as a master copy, and replacing the one of the first and second files with the earlier expiration date with a soft link pointing to the master copy.
