A combination of non-rotating storage and associated software temporarily transfers storage functions from a hard disk to the non-rotating storage. This invention provides for the “on the fly” adaptation and transfer of an application's disk requirements to be instead sent to a flash storage, non-spinning memory device, solid state memory, or similar device while the hard drive is powered down. This not only makes operations faster, but results in a large savings in battery power.

An intelligent caching data structure and mechanisms for storing visual information via objects and data representing graphics information. The data structure is generally associated with mechanisms that intelligently control how the visual information therein is populated and used. The cache data structure can be traversed for direct rendering, or traversed for pre-processing the visual information into an instruction stream for another entity. Much of the data typically has no external reference to it, thereby enabling more of the information stored in the data structure to be processed to conserve resources. A transaction / batching-like model for updating the data structure enables external modifications to the data structure without interrupting reading from the data structure, and such that changes received are atomically implemented. A method and mechanism are provided to call back to an application program in order to create or re-create portions of the data structure as needed, to conserve resources.

A networking system is disclosed that provides synchronization of information over the network using instantaneous, real time smart cache refreshing. The network utilizes a combination of a synchronous programming scripts, smart cached user requests and preferences, and semi-distributed processing, to optimize information flow, management, and updating over the network system.

Pre-caching may decrease the response time necessary for a wireless communication network to fulfill a user request. Pre-caching includes predicting what data the user will request next and preemptively fetching that data from a network (e.g., the Internet). Additionally, the wireless communication network may predict the geographic location of the mobile device when it makes the request. Instead of pre-caching the data in the memory of the mobile device, the data may be stored at a wireless access point that has a radiation pattern that covers the predicted geographic location of the mobile device. Once the wireless access point receives the request from the mobile device for the pre-cached data, the pre-cached data may be transmitted wirelessly to the mobile device, thereby avoiding having to forward the request to rest of the communication network.

An Intelligent Caching Tool collects reliability statistics for an application server to build a Hidden Markov Model. Using the Hidden Markov Model, the Intelligent Caching Tool calculates a reliability index for the application server. After setting a user defined reliability threshold, the Intelligent Caching Tool caches all client requests and the status of the application server's response when the reliability index is below the reliability threshold.

Methods and systems to distribute cached information for efficient processing without overloading system resources. In an embodiment, VGENs can be implemented as software engines that can reside on a web server or another server that responds to requests for information in a networked environment. A hash table can identify whether a VGEN exists with cached information to process the request. If an available VGEN engine includes the cached information, the available VGEN is assigned to process the request; otherwise, another available VGEN can be selected to process the request, wherein the VGEN is augmented to include the cached information and the hash table is updated to reflect the VGEN statistics. VGENs can maintain persistent connections to databases, file systems, session manager daemons, real-time data sources, etc., to facilitate the processing of requests.

A Hard Disk Drive (HDD) is provided two FATs and two cluster sizes, a regular cluster and a “Supercluster”. In one example, each Supercluster is the size of four regular clusters. A second Supercluster FAT is added (FAT2) which works in a similar manner to the original FAT (hereinafter FAT1), but instead points to the next Supercluster in the chain. Since there are far fewer Superclusters than clusters, the Supercluster FAT (FAT2) can be stored in a cache memory. When data is streamed to and from the hard drive, it can be streamed to Superclusters and no seeks on the HDD to a FAT are required, as the FAT2 is cached in memory. Access time to and from the hard drive is decreased. The original cluster configuration is still supported. During lulls in system operation, the FAT2 data may be written to the drive and moreover, FAT1 data created and “flushed” to the hard drive. Thus, if the HDD is read by a standard computer system, it will recognize the regular clusters from the FAT1 table in a transparent manner (and ignore the FAT2 table).

A network storage server has a non-volatile mass storage facility, a main cache and a victim cache. A technique of intelligently determining whether to cache a data block in the victim cache includes determining whether to store the data block in the victim cache based on a first caching policy and the type of data contained within the data block. The first caching policy may be a global policy. The determination of whether to store the data block in the victim cache further may be based on a second caching policy, which may be a volume-specific control of service (CoS) policy.

A method and system for cooperatively caching digital content in a vehicle for sharing with other vehicles in a vehicle-to-vehicle network. A content utility value is assigned to each piece of digital content available on the network, where the utility value is a function of the popularity of the content, the freshness of the content, and the size of the content. Any piece of content with a sufficiently high content utility value is stored in a host vehicle's collective cache, so that other vehicles may be able to retrieve it quickly on demand. The host vehicle may cache a particular piece of digital content even if the host vehicle is not interested in it. The host vehicle periodically re-computes the content utility value for all digital content in the vehicle's cache to determine if any of the data should be evicted from the cache.

This disclosure describes systems, methods, and apparatus for ERP reporting using a cache server to cache previous query results. Query latency is further reduced by routing queries and responses to queries through the cache server rather than via direct communication between a querying device and a server hosting the database. This is done by moving a driver for interfacing with the database to the server hosting the database, thus avoiding slow protocol communications between this driver and the database when such communications occur over a WAN. A custom driver is also designed to interface with the cache server and control routing of queries and responses through the cache server. Further, a cache server is selected that enables queries to be passed straight to the server hosting the database rather than the query device having to pass these queries to the database.
