A method of securely storing data to a dispersed data storage system is disclosed. A data segment is arranged along the columns or rows of an appropriately sized matrix. Data slices are then created based on either the columns or the rows so that no consecutive data is stored in a data slice. Each data slice is then stored in a separate storage node.

A method, system, apparatus, and computer-readable medium are provided for dynamically provisioning available space in a data storage system without having to configure partitions at system startup. According to one method, a system table is maintained that includes entries corresponding to provisions within the available physical capacity of a data storage system. A volume table is also maintained that includes entries corresponding to territories within a logical data storage volume. When a data write operation is requested, a determination is made as to whether physical space has been allocated for the territory in the volume that is to be written. If physical space has not yet been allocated, the necessary physical space is allocated for the territory within the logical volume that is to receive the written data by creating a pointer to an available entry in the system table in an entry in the volume table corresponding to the territory to be written. Once the physical space has been allocated, the requested write operation is performed. Metadata is written to disk in a fashion that makes it easy to recover from system crashes and unclean shutdowns.

A non-copyable data storage disk (NCDisk) that may be used in a secure data storage system. Stored data items on the NCDisk may only be used through the data storage system, and cannot be copied to and used by any other devices. Digital data written to the NCDisk is automatically converted to a new format by the NCDisk itself before being stored on it. Similarly, when reading a data item out from the NCDisk, the NCDisk itself automatically converts the stored data item to a new data format that a reading device can recognize. Data conversion does not involve the computer operating system. The data conversion unit may include a chipset level 2 secure key management module that generates and manages the keys used for the data conversion.

The invention discloses a data storage system and a data storage method. The system comprises a label and card manufacturing subsystem, a background management subsystem, a first data storage subsystem and a second data storage subsystem, wherein the first data storage subsystem and the second data storage subsystem are used for association control; different association data of the same object is respectively placed in different data storage subsystems; only one of the data storage subsystems for storing the different relative data of the same object can be opened at a time through setting; and moreover, as long as the data acquired from the data storage subsystems is authorized data, the other data storage subsystem for storing another association data of the object can be opened. By applying the invention, the safety of data storage can be improved.

The invention provides a consistency dynamic adjustment method and device in a distributed data storage system. The consistency dynamic adjustment method comprises the steps that a coordinating node obtains performance parameters of the distributed data storage system; the coordinating node calculates probability of inconsistency which corresponds to each copy response waiting to be returned of a user request in the distributed data storage system and a system delay; and the coordinating node obtains at least one first response number with the probability of inconsistency and the system delay meeting a preset condition based on the probability of inconsistency corresponding to each response number and the system delay.

The controller includes a PCIE end point for transferring atomic operation (DSA) requests, a data pipe section having a plurality of data pipes for passing user data; and a message engine section for passing messages among the plurality of storage processors. An acceleration path controller bypasses a DSA buffer in the absence of congestion on the network. Packets fed to the PCIE end point include an address portion having code indicating an atomic operation. An encoder converts the code from a PCIE format into the same atomic operation in SRIO format. Each one of a plurality of CPUs is adapted to perform a second DSA request during execution of a first DSA request.

Methods and systems are provided for storing data holographically. Multiple distinct data packets are received. The data packets are stored on a temporary data storage. Data that includes the data packets are written holographically during a single write session to a photopolymer storage medium by optically interfering an optical data beam with an optical reference beam. The data are written physically to a data region on the photopolymer storage medium. A bleaching area of the photopolymer storage medium is exposed to a bleaching illumination to optically fix the bleaching area and prevent data from subsequently being written to the bleaching area. The bleaching area includes the data region.

The present invention is directed to a distributed data migration and storage system and method configured for fully parallel writing and retrieval of data objects to (and from) the Web Object Scaler (WOS) object storage system with highly efficient accessibility and using a simplified set of filing commands. The data objects migrate between data generating entities and the WOS object storage through an intermediate Burst Buffer tier (supported by the Infinite Memory Engine) without the utilization of a serial process substantially simultaneously through parallel channels. The metadata for each object is captured with appropriate pointers for efficient finding of the object in the WOS storage system. The WOS nodes return the stored objects' ID (OIDs) corresponding to the objects storage address which are used for the object access.
