Systems and methods for grouping mesh networks. Mesh networks enable energy data to be transferred from an energy sensing device to a destination device using various networks and reduces the need to install metering stations. Embodiments of the invention join or group mesh networks that otherwise are not able to communicate. The connections between the grouped mesh networks can be passive using directional antennas or passive antennas or active using higher power RF devices, solar repeaters, mobile mesh devices, etc. The energy data is routed in a smart manner, by performing load balancing at gateways, by monitoring the signal to noise ratio of available communication paths, etc. Mesh clusters can also be created to define low power clusters, address blocking clusters, and frequency based clusters. Grouping clusters facilitates the efficient transfer of energy data from an energy sensing device to a energy management station.

A traditional structured data store is leveraged to provide the benefits of an unstructured full-text search system. A fixed number of “extended” columns is added to the traditional structured data store to form an “enhanced structured data store” (ESDS). The extended columns are independent of any regular columnar interpretation of the data and enable the data that they store to be searched using standard full-text query syntax / techniques that can be executed faster (as opposed to SQL syntax). In other words, the added columns act as a search index. A token is stored in an appropriate extended column based on that token's hash value. The hash value is determined using a hashing scheme, which operates based on the value of the token, rather than the meaning of the token. This enables subsequent searches to be expressed as full-text queries without degrading the ensuing search to a brute force scan.

Systems and methods for providing accelerated data storage and retrieval utilizing lossless data compression and decompression. A data storage accelerator includes one or a plurality of high speed data compression encoders that are configured to simultaneously or sequentially losslessly compress data at a rate equivalent to or faster than the transmission rate of an input data stream.

A method for managing a data storage system includes maintaining a record predictive of locations to which data are to be written on a first storage medium by a host computer. Upon receiving a write command from the host computer directed to storing specified data at a specified location on the first storage medium, if the specified location is not included in the record, the record is updated responsively to the specified location. A signal is sent to the host computer that the specified data have been stored in the data storage system responsively to storing the specified data and, if the specified location was not included in the record, responsively to updating the record. The specified data are copied to the second storage medium responsively to the record, and are stored in the specified location on both the first and second storage media.

Easily implemented randomization within a flash memory EEPROM reduces the NAND string resistance effect, program disturbs, user read disturbs, and floating gate to floating gate coupling that result from repeated and long term storage of specific data patterns. The randomization may be code generated pseudo randomization or user driven randomization in different embodiments. User driven commands, the timing of which cannot be predicted may be used to trigger and achieve a high level of randomization. Randomly altering the encoding scheme of the data prevents repeated and long term storage of specific data patterns. Even if a user wishes to store the same information for long periods, or to repeatedly store it, it will be randomly encoded with different encoding schemes, and the data pattern will therefore be varied.

In order to provide a low noise laser beam, a noise reducing feedback network is provided which creates a noise reducing signal and provides that signal to the laser itself. In order to produce the noise reducing signal, the operation of the laser is monitored and the feedback signal is a direct result of this monitoring. Monitoring is accomplished by a fast-forward sense detector, which receives a portion of the laser beam from the operating laser. The output from this fast-forward sense detector is provided to an amplifier which inverts and amplifies the signal. A noise reduction feedback network then receives the amplified signal, appropriately filters this signal, and provides it to the laser itself so as to reduce noise in the laser-beam for the frequency band of importance for reading the recorded data from the optical medium. The noise reduction feedback signal further has sufficiently high impedance so as to not disturb the traditional CW operation of the laser and to avoid interference with the traditional RF modulation of the laser.

A data storage system includes controller nodes and a storage component. The controller nodes couple the storage component to a host. The storage component includes a controller and sleds with disk drives. The host and the storage component form an arbitrated loop. When the arbitrated loop is down, the controller removes the storage component from the arbitrated loop so the controller, the sleds, and the disk drives form an internal loop. When the internal loop is also down, the controller tests each of the sleds individually and marks those that are not responding properly. If a sled is responding properly the controller tests each of the drives in that sled individually and marks those that are not responding properly. The controller adds back into the internal loop the sleds and the drives that are not marked as bad, and then the storage component back into the arbitrated loop.

Techniques are disclosed for storing content in distributed computing environments to reduce storage overhead and improve efficiency and / or speed of accessing and delivering the stored content. A content management system (or other authoring system, such as a text editor) supplies hints about dependencies among objects or files, such as which objects are embedded into a web page and which objects are referenced by the web page. These hints are then used when deploying the corresponding files on a storage system, such that the files which are likely to be retrieved together are (preferably) stored together. Optionally, run-time observations by a web server may be used as input to this process to determine how best to store content during a subsequent redeployment.

A ferroelectric nanostructure formed as a low dimensional nano-scale ferroelectric material having at least one vortex ring of polarization generating an ordered toroid moment switchable between multi-stable states. A stress-free ferroelectric nanodot under open-circuit-like electrical boundary conditions maintains such a vortex structure for their local dipoles when subject to a transverse inhomogeneous static electric field controlling the direction of the macroscopic toroidal moment. Stress is also capable of controlling the vortex's chirality, because of the electromechanical coupling that exists in ferroelectric nanodots.

A data storage device with improved data storage densities, coupled with lower hard error and write-inhibit events is described. A feed-forward write inhibit (FFWI) method enables data tracks to be written more densely. Alternatively, the FFWI method may reduce the hard error and write inhibit events to improve data storage performance. A concept of virtual tracks enables the FFWI method to be applied to the writing of circular data tracks with non-circular servo tracks, or to the writing of non-circular data tracks with PES data from circular servo tracks—in both cases, improvements to performance and / or storage densities are enabled. The FFWI method may also be applied to the case of both non-circular servo and data tracks.
