A mechanism is described for provisioning remote desktops in a cloud based infrastructure while maintaining user personalization. In cloud based systems, a user may not always reconnect to the same VM endpoint. In one embodiment, the virtual hard disk assigned to a user is mounted to the endpoint assigned to the user. The virtual hard disk includes the user's personal data and personalization information (e.g., settings, profiles, files, etc.). When the user disconnects from the remote desktop, the virtual hard disk is demounted from the endpoint. The virtual hard disk thus provides information regarding the user's state when the user is disconnected.

In an aggregated file system, a method of processing a user file retrieves user file metadata and user data from a metadata server and applies operations to the user data in accordance with a file open request from a client. At the end of the process, the method stores the processed user data at a location in accordance with a predefined rule and updates the metadata in the metadata server to reference the processed user data at the location. In some embodiments, the predefined rule is to choose a location between the metadata server and a separate storage server in accordance with the size of the processed user data. If the size is still smaller than a predetermined threshold, the user data is stored in the metadata server. Otherwise, the user data is stored in the storage server.

In a switched file system, a file switching device is logically positioned between clients and file servers and communicates with the clients and the file servers using standard network file protocols. The file switching device appears as a server to the client devices and as a client to the file servers. The file switching device aggregates storage from multiple file servers into a global filesystem and presents a global namespace to the client devices. The file switching device typically supports a 'native' mode for integrating legacy files into the global namespace and an 'extended' mode for actively managing files across one or more file servers. Typically, native-mode files may be accessed directly or indirectly via the file switching device, while extended-mode files may be accessed only through the file switching device. The file switching device may manage file storage using various types of rules, e.g., for managing multiple storage tiers or for applying different types of encoding schemes to files. Rules may be applied to pre-existing files.

File aggregation in a switched file system

A method of operating a multi-dimensional database is disclosed. In this method, a multi-dimensional portion of the data is transferred to a multi-dimensional database. A relational portion of the cube is kept in the relational database. When data from the relational portion needs to be accessed, the system produces the SQL queries to obtain data from the relational database.
