System and method for enabling de-duplication in a storage system architecture
ActiveUS7747584B1Effectively ensureImprove efficiencyDigital data information retrievalDigital data processing detailsData contentData store
A system and method enables de-duplication in a storage system architecture comprising one or more volumes distributed across a plurality of nodes interconnected as a cluster. De-duplication is enabled through the use of file offset indexing in combination with data content redirection. File offset indexing is illustratively embodied as a Locate by offset function, while data content redirection is embodied as a novel Locate by content function. In response to input of, inter alia, a data container (file) offset, the Locate by offset function returns a data container (file) index that is used to determine a storage server that is responsible for a particular region of the file. The Locate by content function is then invoked to determine the storage server that actually stores the requested data on disk. Notably, the content function ensures that data is stored on a volume of a storage server based on the content of that data rather than based on its offset within a file. This aspect of the invention ensures that all blocks having identical data content are served by the same storage server so that it may implement de-duplication to conserve storage space on disk and increase cache efficiency of memory.

A method and system for storing instructions retrieved from memory in a memory cache to provide said instructions to a processor. First a new instruction is received from the memory. The system then determines whether the new instruction is a start of a basic block of instructions. If the new instruction is the start of a basic block of instructions, the system determines whether the basic block of instructions is stored in the memory cache responsive. If the basic block of instructions is not stored in the memory cache, the system retrieves the basic block of instructions for the new instruction from the memory. The system then stores the basic block of instructions in a buffer. The system then predicts a next basic block of instructions needed by the processor from the basic block of instructions. The system determines whether the next block of instructions is stored in the cache memory and retrieves the next basic block of instructions from the memory if the next block of instructions is not stored in memory.

Methods and apparatus for serving content to customer devices based on dynamic content popularity
Methods and apparatus for processing requests for content received from customer devices are described. A decision on how to respond to a request for content is made at an edge node based on a locally maintained popularity list. The local popularity list reflects the local popularity of individual pieces of content at the edge node. A white list of content to be cached and served irrespective of popularity is sometimes used in combination with the local popularity list to make decisions as to how to respond to individual requests for content. In some embodiments the edge node decides on one of the following responses to a content request: i) cache and serve the requested content; ii) serve but don't cache the requested content; or iii) redirect the content request to another node, e.g., an alternate serving node, which can respond to the content request.
