| 20100088277 | OBJECT DEDUPLICATION AND APPLICATION AWARE SNAPSHOTS - Embodiments deploy delayering techniques, and the relationships between successive versions of a rich-media file become apparent. With this, modified rich-media files suddenly present far smaller storage overhead as compared to traditional application-unaware snapshot and versioning implementations. Optimized file data is stored in suitcases. As a file is versioned, each new version of the file is placed in the same suitcase as the previous version, allowing embodiments to employ correlation techniques to enhance optimization savings. | 04-08-2010 |
| 20100094806 | File storage system, cache appliance, and method - A file storage system for storing data of a file received from a client includes a back-end file server in which the data is stored. The system includes a cache appliance in communication with the file server, such that the appliance stores portions of the data or attributes of the file, and uses the stored data or attributes to process file system requests received from the client, and which reads and writes data and attributes to the back-end file server independently. A system for responding to a file system protocol request in regard to a back-end server includes a token server. The system includes a plurality of cache appliances in communication with the token server, each of which receives tokens from the token server to synchronize access to data and attributes caches of the cache appliances, and reading and writing data and attributes to the back-end servers when tokens are revoked, the cache appliance having persistent storage in which data are stored, and the token server having persistent storage in which tokens are stored. A storage system includes a plurality of backend servers. The system includes a token server which grants permission to read and write file attributes and data system, and includes a plurality of cache appliances in communication with at least one of the backend servers and the token server for processing an incoming NFS request to the one backend server. Each cache appliance comprises an NFS server which converts incoming NFS requests into cache manager operations; a token client module in communication with the token server having a cache of tokens obtained from the token server; a cache manager that caches data and attributes and uses tokens from the token client module to ensure that the cached data or attributes are the most recent data or attributes, and an NFS client which sends outgoing NFS requests to the back-end file server.

| 20100280993 | ACTIVE/PUSH NOTIFICATION FACADE FOR A PASSIVE DATABASE SYSTEM - Systems, methods, computer program product embodiments for an active/push notification facade for a passive database are described herein. An embodiment includes an event listener configured to poll (or query) a passive database and selectively retrieve data objects based on the poll results. Such a selective database read operation may be based on the priority of an event occurring in the passive database. If events of a low priority occur, the event listener does not open the passive database immediately to retrieve additional information related to the low priority event but defers reading the passive database by a pre-determined amount of time. If a higher priority event occurs, the passive database is immediately read to retrieve details related to the high priority event from the passive database. In another embodiment, event listener reads the passive database based on event timestamp information in the passive database and stored timestamp information. | 11-04-2010 |

| 20140201147 | Migration of Feedback Data to Equivalent Digital Assets - Methods and systems for managing for migrating feedback data from one digital asset to another digital asset are disclosed. Typically, the one digital asset is available for distribution from a network-based media distribution system, but then subsequently is removed from distribution for any of a number of reasons. However, since the one digital asset has been in use at the network-based media distribution system, it has accumulated feedback data. Hence, if the another digital asset serves (e.g., due to equivalency) to replace the one digital asset, then the accumulated feedback data from the one digital asset can be transferred to the another digital asset. As a result, the another digital asset can benefit from the feedback data that was previously associated with the one digital assert. | 07-17-2014 |
