20120117035 | FILE SYSTEM CONSISTENCY CHECK ON PART OF A FILE SYSTEM - A file system that includes multiple logical devices can be subdivided into multiple containers. The containers each include respective non-overlapping sets of the logical devices. An amount of memory allocated to a container is dynamic.

20130275653 | MULTI-TIER STORAGE USING MULTIPLE FILE SETS - Storage locations in a first tier of a multi-tier storage system are allocated to a first set of data structures (e.g., inodes) in a first file set. A file that is stored in the first tier is associated with a first data structure of the first set. In response to determining that data in the file should be moved to a second tier of the multi-tier storage system, the file is associated with a second data structure in a second file set. The second data structure is allocated a storage location in the second tier. Consequently, two data structures are associated with the file. The data is copied from the first tier to the storage location in the second tier, and can be subsequently accessed using the second data structure. | 10-17-2013 |
20130346724 | SEQUENTIAL BLOCK ALLOCATION IN A MEMORY - A region of memory is logically divided into a number of segments, each of which is logically divided into a number of blocks. Blocks are allocated sequentially. A head pointer and a tail pointer demarcate the section of allocated blocks. As allocated blocks are added, the tail pointer is moved so that it remains at the end of the section of allocated blocks. If the tail pointer is within a threshold distance of the head pointer, then the head pointer is moved from its current position to a new position, and the allocated blocks between the current and new positions are freed (deallocated and/or erased). Thus, writes to the memory can be performed sequentially, and blocks can be freed in advance of when they are actually needed. | 12-26-2013 |

20090313483 | Single Instance Storage of Encrypted Data - Described is a technology by which data is efficiently and securely stored in a single instance store. A hash value is computed from data in its unencrypted form. The hash value is used to reference a single instance of that data when stored in its encrypted form. In this manner, duplicate data blocks are detectable independent of their encryption, yet stored in an encrypted form in a single instance store. In one aspect, context information for decrypting the encrypted data is stored in association with the data. When the client wants to restore the data, the client sends the hash value for that block to the single instance store service. The service returns the block and the associated context information. The client uses the context information to decrypt the block. For example, the context may comprise a key identifier which the client uses to lookup the correct key. | 12-17-2009 |

20110219201 | COPY ON WRITE STORAGE CONSERVATION SYSTEMS AND METHODS - Systems and methods for copy on write storage conservation are presented. In one embodiment a copy on write storage conservation method includes creating and mounting a snapshot; mounting a snapshot; monitoring interest in the snapshot; initiating a copy on write discard process before a backup or replication is complete; and deleting the snapshot when the backup or replication is complete. In one embodiment the method also includes marking a file as do not copy on write. In one embodiment, the copy on write discard process includes discarding copy on write data when a corresponding read on the file in the snapshot is successful. Initiating a copy on write discard process can be done at a variety of levels (e.g., a file level, an extent level, a block-level, etc.). | 09-08-2011 |

20090254916 | ALLOCATING RESOURCES FOR PARALLEL EXECUTION OF QUERY PLANS - Computing resources can be assigned to sub-plans within a query plan to effect parallel execution of the query plan. For example, computing resources in a grid can be represented by nodes, and a shortest path technique can be applied to allocate machines to the sub-plans. Computing resources can be provisionally allocated as the query plan is divided into query plan segments containing one or more sub-plans. Based on provisional allocations to the segments, the computing resources can then be allocated to the sub-plans within respective segments. Multiprocessor computing resources can be supported. The techniques can account for data locality. Both pipelined and partitioned parallelism can be addressed. Described techniques can be particularly suited for efficient execution of bushy query plans in a grid environment. Parallel processing will reduce the overall response time of the query. | 10-08-2009 |
