Abstract: Using replication to create storage service tiers, including: receiving a request for data stored in a first storage array and not stored in a second storage array associated with a lower latency tier than the first storage array; providing the data from the first storage array in response to the request; and asynchronously replicating the data from the first storage array to the second storage array.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for managing or tracking assets in a geographical area. One method includes providing a plurality of travel routes to a plurality of assets located in a geographical area, wherein each of the plurality of travel routes indicates a route along which a corresponding asset of the plurality of assets is to travel, and wherein the plurality of travel routes are based on an analysis of travel history of one or more of the plurality of assets. The method also includes receiving a request from a client device to travel to a destination in the geographical area. The method further includes determining, by one or more computer processors, one or more travel routes of the plurality of travel routes to the destination, wherein the one or more travel routes use different assets to travel to the destination. The method also includes providing the one or more travel routes to the client device.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for managing or tracking assets in a geographical area. One method includes receiving one or more first messages from a plurality of assets on one or more first channels of a plurality of channels. The one or more first messages may indicate live geographical locations of the plurality of assets located in a geographical area. The method also includes displaying, via a graphical user interface, the live geographical locations of the plurality of assets on a map of the geographical area. The method further includes receiving on a second channel a message indicating a request from a first user device to travel to a destination. The method further includes determining one or more travel routes to the destination. The one or more travel routes may use different assets to transport the first user device to the destination.

Abstract: Techniques, systems, and articles of manufacture for input/output de-duplication based on variable-size chunks. A method includes partitioning virtual block data into multiple variable-sized chunks, caching each of the multiple variable-sized chunks in a chunk cache according to content of each of the multiple variable-sized chunks, initializing virtual block-to-chunk mapping and chunk-to-physical block mapping for each of the multiple variable-sized chunks, and detecting duplicate disk input and/or output requests across multiple hosts based on content-based mappings of the input and/or output requests to the chunk cache and the virtual block-to-chunk mapping and chunk-to-physical block mapping for each of the multiple variable-sized chunks in the chunk cache.
