Abstract: A shared implementation for multiple system interfaces. An embodiment of a method includes receiving a command for a system, the command being a command for one of a plurality of interfaces for the system; generating a data structure for the command, the data structure including an opcode from a common library; and parsing the command using one of a plurality of parsing functions, parsing of the command including inserting an argument from the command into the data structure for the command.

Abstract: Interfaces for flexible storage management. An embodiment of a system includes a data storage, the data storage including one or more of a first storage system, the first storage system including a file structure that is coextensive with a set of memory devices, or a second storage system, the second storage system including a storage structure that is coextensive with a set of memory devices, the storage structure including zero or more file structures. The system further includes an interface system for the data storage, the interface system being used for both the first storage system and the second storage system.

Abstract: A method of serializing administrative operations on virtual volumes includes operating a storage system to maintain a plurality of virtual volumes that share a pool of block storage, where each of the virtual volumes containing data stored on one or more physical storage devices. Administrative access to each of the virtual volumes is controlled individually by imposing serialization on administrative operations directed to each virtual volume.
