摘要： Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for storing data on storage nodes. In one aspect, a method includes receiving a file to be stored across a plurality of storage nodes each including a cache. The is stored by storing portions of the file each on a different storage node. A first portion is written to a first storage node's cache until determining that the first storage node's cache is full. A different second storage node is selected in response to determining that the first storage node's cache is full. For each portion of the file, a location of the portion is recorded, the location indicating at least a storage node storing the portion.

摘要： A storage system may include a set of storage devices; a controller; and a management device. The controller may arbitrate among operations for execution by the set of storage devices, where the operations are received from users that are associated with priority levels. The controller may maintain queues, corresponding to the users, to queue operations from the users. The controller may additionally include a scoring component and a scheduler. The scoring component may maintain a score for each queue. The scheduler may choose, from the queues and based on the score of each queue, one of the operations to service. The management device may receive usage updates, from the controller, reflecting usage of the set of storage devices; calculate a maximum allowed usage levels, based on the received usage updates, for each user; and transmit the calculated maximum usage levels to the controller.

摘要： A system may identify a first document associated with a geographic location within a geographical area and identify a second document associated with a geographic location outside the geographical area. The system may also assign a first score to the first document based on a first scoring function and assign a second score to the second document based on a second scoring function.

摘要： One embodiment of the present invention provides a system that automatically determines if a location is a standalone location, which can be unambiguously identified by a name for the location alone. During operation, the system determines a name score for the location which indicates a popularity of the name for the location. The system also obtains a signature for the location, wherein the signature is a set of combinations of location specifiers, wherein each combination of location specifiers refers to the location. The system then determines a signature score for the location which indicates a popularity of the signature for the location. Finally, the system determines whether the location is a standalone location based on the name score and the signature score.
