Abstract: A write allocation technique extends a conventional write allocation procedure employed by a write anywhere file system of a storage system. A write allocator of the file system implements the extended write allocation technique in response to an event in the file system. The extended write allocation technique efficiently allocates blocks, and frees blocks, to and from a virtual volume (vvol) of an aggregate. The aggregate is a physical volume comprising one or more groups of disks, such as RAID groups, underlying one or more vvols of the storage system. The aggregate has its own physical volume block number (pvbn) space and maintains metadata, such as block allocation structures, within that pvbn space. Each vvol also has its own virtual volume block number (vvbn) space and maintains metadata, such as block allocation structures, within that vvbn space.

Abstract: Methods and apparatuses that search tree representations of a bitmap for available blocks to allocate in storage devices are described. An allocation request for a file may be received to initiate the search. In one embodiment, the bitmap may include an array of bits corresponding to blocks in the storage devices. Each bit may indicate whether one of the blocks is available. The tree representations may include at least one red-black tree having nodes corresponding to one or more consecutive bits in the bitmap indicating an extent of available blocks. One of the tree representations may be selected according to a file associated with an allocation request to identify an extent of available block matching the allocation request. The tree representations may be synchronized as the bitmap is updated with changes of block allocations in the storage devices.

Abstract: The main purpose of the software, system and method of this invention is to help produce better searches for people utilizing their context as represented by a vector. The system allows for files (including websites) to be tagged with a vector. If a provider wants a searcher to find that provider's files, the file must be tagged with the vector that is sufficiently close to the searcher's corresponding vectors. A search user inputs not only a text search but also the vectors that have been created to show the context and preferences of that search user.

Abstract: A method and apparatus for creating a non-uniform index structure for data are disclosed. For example, the method sets at least one threshold for at least one of: a number of objects in a cell, or a maximum number of decompositions for a cell. The method creates a plurality of cells by overlaying a grid over a plurality of objects and decomposes each of the plurality of cells until either the maximum number of decompositions is reached, or the number of objects in each cell is below the at least one threshold for numbers of objects in a cell. The method then creates a key for each cell, and creates an index structure for the data using said key for each cell.

Abstract: A method and system for parsing of input addresses for further automated processing. A relevant locale for an input address is determined. Based on the locale, an applicable parsing tree is provided so that different address formats can be tested against the input address. The parsing tree is generated from a local address format specification that defines permissible formats for the locale. The local address format specification and the local address component rules are provided to a parsing engine to determine one or more potential parsed addresses based on compliance with specifications. The local address component rules specification is applied to the input address to determine one or more branches of the parsing tree for which the input address matches criteria of the component rules specification. Penalties may be assigned to branches of the tree when disfavored matches occur.
