A set of resource fallback rules are followed to traverse the hierarchy and to locate a corresponding data item for the subject resource in the hierarchy. | 07-22-2010 |
| 20110185401 | REAL-TIME ADJUSTMENTS TO AUTHENTICATION CONDITIONS - Embodiments of the invention provide for adjusting authentication conditions in real-time. A graph-theoretic data structure is dynamically constructing, having nodes corresponding to received valid and invalid authentication credentials used in attempts to access a system. Based on the graph-theoretic data structure, embodiments compute a probability of an invalid credential being an authentication attempt by a particular type of user. If the probability is beyond a threshold probability, embodiments trigger a security event is to adjust an authentication condition of the system, e.g., to increase or decrease a maximum permissible number of failed login attempts within a certain period of time. | 07-28-2011 |

| 20090112949 | COMPRESSED STORAGE MANAGEMENT - In accordance with one or more aspects, compressed storage management in a system includes determining which of multiple data units stored in an uncompressed portion of the storage resource are to be compressed and stored in a compressed portion of the storage resource. The management can further include returning one or more regions of the compressed portion for use in the uncompressed portion in response to storage resource pressure in the system, as well as compacting regions in the compressed portion to fill empty gaps in the compressed portion. | 04-30-2009 |
| 20090150611 | MANAGEMENT OF EXTERNAL MEMORY FUNCTIONING AS VIRTUAL CACHE - A method and apparatus for managing the caching of data on an auxiliary memory of a computer. Pages of data may be cached on an auxiliary memory, such as a flash memory, at a virtual level using an identifier that does not involve a physical address of the pages on a memory. Pages may be cached on auxiliary memory that may be removable from the computer, e.g., by unplugging the memory from the computer. Page data may be encrypted and/or compressed on the auxiliary memory. An authentication indicator may be used to verify the accuracy of cached data in the case of an interrupted connection to the auxiliary memory, e.g., as a result of computer power down, hibernation, removal of the memory from the computer, etc. | 06-11-2009 |
| 20090198883 | DATA COPY MANAGEMENT FOR FASTER READS - Multiple copy sets of data are maintained on one or more storage devices. Each copy set includes at least some of the same data units as other sets. Different sets optionally have data units stored in different orders on the storage device(s). A particular one of the sets of data is selected as the set to be accessed in response to detecting a particular scenario. | 08-06-2009 |
| 20100070701 | MANAGING CACHE DATA AND METADATA - Embodiments of the invention provide techniques for ensuring that the contents of a non-volatile memory device may be relied upon as accurately reflecting data stored on disk storage across a power transition such as a reboot. For example, some embodiments of the invention provide techniques for determining whether the cache contents and/or or disk contents are modified during a power transition, causing cache contents to no longer accurately reflect data stored in disk storage. Further, some embodiments provide techniques for managing cache metadata during normal (“steady state”) operations and across power transitions, ensuring that cache metadata may be efficiently accessed and reliably saved and restored across power transitions. | 03-18-2010 |
| 20100070747 | MANAGING CACHE DATA AND METADATA - Embodiments of the invention provide techniques for managing cache metadata providing a mapping between addresses on a storage medium (e.g., disk storage) and corresponding addresses on a cache device at data items are stored. In some embodiments, cache metadata may be stored in a hierarchical data structure comprising a plurality of hierarchy levels. Only a subset of the plurality of hierarchy levels may be loaded to memory, thereby reducing the memory “footprint” of cache metadata and expediting the process of restoring the cache metadata during startup operations. Startup may be further expedited by using cache metadata to perform operations associated with reboot. Thereafter, as requests to read data items on the storage medium are processed using cache metadata to identify addresses at which the data items are stored in cache, the identified addresses may be stored in memory. When the computer is later shut down, instead of having to transfer the entirety of the cache metadata from memory to storage, only the subset of the plurality of hierarchy levels and/or the identified addresses previously loaded to memory may be transferred (e.g., to the cache device), thereby expediting the shutdown of the computer. | 03-18-2010 |
| 20110113432 | COMPRESSED STORAGE MANAGEMENT - Compressed storage management includes assigning a selection priority and a priority level to multiple data units stored in an uncompressed portion of a storage resource. The management can further include compressing data units and storing the compressed data units in a compressed portion of the storage resource. The data units in the compressed portion are stored in regions, which each store data units having the same selection priority or the same selection priority level. | 05-12-2011 |
| 20110271070 | MEMORY USAGE SCANNING - A memory scanning system may scan memory objects to determine usage frequency by scanning each memory object using a mapping of the processes stored in memory. The scanning may be performed multiple times to generate a usage history for each page or unit of memory. In some cases, scanning may be performed at different frequencies to determine multiple classifications of usage. The mapping may create a detailed topology of memory usage, including multiple classifications of access frequency, as well as several other classifications. Based on the topology, the objects in memory may be copied to another storage medium or optimized for performance or power consumption. | 11-03-2011 |
| 20110314202 | MANAGING CACHE DATA AND METADATA - Embodiments of the invention provide techniques for managing cache metadata providing a mapping between addresses on a storage medium (e.g., disk storage) and corresponding addresses on a cache device at data items are stored. In some embodiments, cache metadata may be stored in a hierarchical data structure comprising a plurality of hierarchy levels. When a reboot of the computer is initiated, only a subset of the plurality of hierarchy levels may be loaded to memory, thereby expediting the process of restoring the cache metadata and thus startup operations. Startup may be further expedited by using cache metadata to perform operations associated with reboot. Thereafter, as requests to read data items on the storage medium are processed using cache metadata to identify addresses at which the data items are stored in cache, the identified addresses may be stored in memory. When the computer is later shut down, instead of having to transfer the entirety of the cache metadata from memory to storage, only the subset of the plurality of hierarchy levels and/or the identified addresses previously loaded to memory may be transferred (e.g., to the cache device), thereby expediting the shutdown of the computer. | 12-22-2011 |
