A data preservation system for flash memory systems with a host system, the flash memory system receiving a host system power supply and energizing an auxiliary energy store therewith and communicating with the host system via an interface bus, wherein, upon loss of the host system power supply, the flash memory system actively isolates the connection to the host system power supply and isolates the interface bus and employs the supplemental energy store to continue write operations to flash memory.

A system and method of operating a storage system is provided. The storage system includes a tape cartridge having a magnetic tape medium and a tape drive for reading and writing data to the magnetic tape medium of the tape cartridge. Performance data associated with specific operating loci (e.g., bands, directions, tracks, segments, etc.) of the tape drive and tape medium are collected, analyzed, and stored, allowing for analysis and detection of trends over time. In one example, tape usage events are monitored and when they cross a threshold the system may remove particular tapes in a preventative maintenance approach to reduce system outage. Performance data is collected and analyzed with a portion of the performance data being saved to emulated medium auxiliary memory (EMAM) on the magnetic tape, and a portion of the of the performance data saved in non-volatile storage in the drive.

A system tool merges different load forecasts for power grid centers. A plurality of load forecast engines are coupled to a load forecast interface and a relational data base that saves load forecast engine data as an input through the load forecast interface. A comprehensive operating plan is coupled to the load forecast engines and the relational database. The comprehensive operating plan is configured to integrate individual load forecasts into a composite load forecast to present a comprehensive, synchronized and harmonized load forecast. A program interface provides access to the composite load forecasting schedule.

A nonvolatile storage device is provided with a nonvolatile main storage memory whose erase size is larger than a cluster size, and a buffer, i.e. a nonvolatile auxiliary storage memory. At the time of writing data in the memory, the data is temporarily stored in the buffer, then, a plurality of data in the buffer are collectively taken out to be stored in the main storage memory. Data in an original block is saved in a write block in the main storage memory. Thus, the data can be written in the main storage memory at a high speed.

The invention relates to an accelerated data query method in a query system, which provides an accelerated data query method based on a cache of document system according to the features of unchanged saved historical data and frequent query of same data. The invention saves the historical query data and takes it as the cache data for query, so as to accelerate the query. Upon receiving the query quest from user, the system will first of all turn to the query analyzer; the principal function of the query analyzer is to analyze and plan the query condition; then, after passing through a document buffer, the system analyzes whether the data document in the result satisfies the present query need; if not, the query will be carried out in the database and the final result will be fed back to a data processor; then, the data processor will filter and sort the data according to the final query demand and finally feed back the result document to a super stratum application system. Therefore, without increasing the investment on hardware, this query method is able to greatly reduce the occupation of database and system resource, so as to improve the query speed.

In a storage switch to control a snapshot operation in the file unit, the delay in the writing operation of a host due to a data saving operation is prevented. In a snapshot acquiring method, the memory usage in a switch is reduced to create a snapshot. The storage switch includes a function to create a snapshot of a file. To prevent occurrence of delay due to the data saving operation, a mirror of source data as a snapshot target is kept in a source volume in any situation or according to a predetermined condition with synchronization established between the mirror and the source data. In the creation of the snapshot, the mirror data is used. By creating the mirror data in sequential positions in the source volume, the positional correspondence between the source side and the snapshot side is simplified.

The invention provides a supermarket intelligent shopping guide system based on WIFI (Wireless Fidelity) indoor positioning and a positioning method. The supermarket intelligent shopping guide system is characterized by comprising a WIFI positioning module, a server end system and an application end system, wherein the WIFI positioning module comprises terminal equipment and hotspot APs (Access Points) distributed in every part in a supermarket; the hotspot APs are used for providing a WIF network for equipment in the supermarket and sending the position information of each hotspot AP to a server; the terminal equipment collects commodity information codes and sends the commodity information codes to the server; and the server is used for receiving information, processing the information, storing the data into a memory, receiving a request of the application end system, sending the position information to the application end system and sending commodity information and advertisements. The method and the system provided by the invention have the advantages that the commodities can be fast and effectively positioned and navigated; the commodity sale promotion information is sent to client equipment in real time; convenience is brought to customers to consume; and the cost of merchants is also reduced.

A high-performance and highly-reliable snapshot management apparatus and method, and storage system are provided that can prevent the adverse influence of overhead when they retain a multiplicity of snapshots. An operational volume is set in a storage area provided by a first storage apparatus and a plurality difference volumes are set in a storage area provided by a second storage apparatus. In response to data writing to the operational volume, difference data is saved in the difference volumes and management tables for it are created, with each snapshot being managed according to the management tables. Each management table is divided according to one or more snapshots in accordance with the snapshot creation time. The second and any following management tables store specified inheritance information to inherit the content of the preceding management tables.

The present application discloses a blockchain-based data transaction method, which utilizes the decentralization feature of the blockchain to solve the defect of centralized storage. Each user is a node in the blockchain network, and the intelligent transaction contract is deployed to the blockchain network to establish a data transaction channel between the data producer and the data purchaser.The data storage uses a distributed storage network with lower storage cost and higher security performance, the tradable data is stored in the form of cipher texts, and data indexes with a very smallamount of data are generated to locate the corresponding cipher texts, which is different from directly saving the data to the blockchain network, thereby effectively reducing the data storage cost.At the same time, the blockchain network saves all transaction records and synchronizes them to all nodes, greatly avoiding the possibility of tampering and making all transaction records public and transparent. The application also discloses a blockchain-based data transaction system, which has the above beneficial effects.
