Abstract: A partial outer parity management system generates a product code based on a partial data block write to a data block and partial outer parity generated by a previous partial data block write to the data block. In one implementation, a storage device includes cache storage circuit accessible by the parity generator, the cache storage circuit being configured to cache the partial outer parity generated by the previous partial data block write to the data block in a partial outer parity cache designated for association with the product code.

Abstract: A fixed data region on a storage medium may be allocated with one of a variety of allocation schemes (e.g., a randomly writable allocation scheme, a non-randomly writeable allocation scheme with a first data isolator spacing, a non-randomly writeable allocation scheme with a second data isolator spacing, and a non-randomly writeable allocation scheme with no dynamic isolators). Dynamic sub-region spacing refers at least to the number of data tracks in a data region of a magnetic disc between dynamic isolators and the number of bits in a data region in flash memory between dynamic isolators. The presently disclosed technology adapts isolators on the storage medium to create dynamic sub-regions based on characteristics of the storage medium, characteristics of the data, and/or expected access patterns of data to be written to the storage medium.

Abstract: Targeted coagulation factors comprising a coagulation factor linked with at least one domain that specifically binds to a membrane protein on a blood cell is provided. The disclosed targeted coagulation factors increase the efficiency of coagulation factors and prolong their duration of action and thus, are an improvement for the treatment of hematological diseases such as hemophilia A.

Abstract: Data stripes and addressing for flash memory devices are provided. Flash memory devices illustratively have a plurality of programmable devices that are capable of simultaneously storing data. A plurality of erasure blocks are within each of the programmable devices, and each erasure block has pages of transistors. The flash memory devices are logically organized as a plurality of stripes. Each stripe has a height and a width. In an embodiment, the stripe height is greater than one page. In another embodiment, the stripe width is less than all of the programmable devices within the flash memory device.

Abstract: A method or system stores a data block redundancy related to a data block of a storage medium together with the mapping metadata for the data block. In an alternative implementation, redundancy storage location is on a separate block of the storage medium, the separate block being in a storage region other than the storage region of the data block.

Further, the controller is adapted to receive state information related to the data storage medium from a plurality of firmware detectors, to weight the received environmental data and the received state information according to a pre-determined weighting table, and to dynamically manage at least one attribute of the storage device based on the weighted environmental data and the weighted state information.

Abstract: Multi-resolution cache monitoring devices and methods are provided. Multi-resolution cache devices illustratively have a cache memory, an interface, an information unit, and a processing unit. The interface receives a request for data that may be included in the cache memory. The information unit has state information for the cache memory. The state information is organized in a hierarchical structure. The process unit searches the hierarchical structure for the requested data.

Abstract: A method or system comprising iteratively updating a value of an operating parameter of a storage region of a storage device based on dynamic characterization of the storage region during operation of the storage device and using the updated value of the operating parameter during access to the storage region.

Abstract: The disclosure is related to systems and methods of dynamic dataflow in a multiple cache architecture. In an embodiment, a system having a data storage device with a multiple cache architecture may detect at least one attribute affecting a data storage workload or data storage performance. The system may select at least one of a plurality of data flow schemes based on the at least one attribute, which may be done to optimize the data storage workload for various conditions. In another embodiment, a data storage controller may automatically and dynamically select one of multiple data flow schemes within a data storage device having a multiple cache architecture. The data storage controller may monitor attributes to determine which data flow scheme to select for various workloads of the data storage device.

Abstract: Values are grouped into a first set of groupings of values. Based on inner codes, the number of groupings in the first set of groupings that have at least one erroneous value is determined. If the number of groupings in the first set of groupings that have an erroneous value is fewer than a maximum number of groupings that can be corrected by outer codes, a seek operation is begun. During the seek operation, the outer codes are used to detect and correct the erroneous values that were produced during the reading of values. In other aspects, a parity section for a data section of a data storage device is dirtied before writing any data to the data section such that if writing to the data section is interrupted, the parity section will indicate that it should not be used to correct data read from the data section.

A controller is communicatively coupled to each of the multiple storage entities. The controller is configured to associate one or more storage attributes of a received object with one or more of the different storage characteristics, and to store the received object in one or more of the multiple storage entities based on the association of the one or more of the storage attributes of the received object with the one or more of the different storage characteristics.

Abstract: The disclosure is related to systems and methods of distributing data in devices with multiple storage entities. In a particular embodiment, a system is disclosed that includes multiple storage entities, with each storage entity having a sub-controller. A controller is communicatively coupled to each of the multiple storage entities. The controller is configured to send at least one of a respective copy of data or metadata associated with the respective copy of the data to each of the multiple storage entities. Upon receipt of the at least one of the respective copy of the data or the metadata associated with the respective copy of the data, each sub-controller provides storage competency information of the respective storage entity for the respective copy of the data. Upon receiving storage competency information for the multiple storage entities, the controller selects a particular one of the multiple storage entities and notifies the selected storage entity to store the respective copy of the data.
