An apparatus includes a processor component of a first node device caused to receive data block encryption data and an indication of size of an encrypted data block distributed to the first node device for decryption, and in response to the data set being of encrypted data: receive an indication of the quantity of sub-blocks within the encrypted data block, and a hashed identifier for each data sub-block; use the data block encryption data to decrypt the encrypted data block to regenerate data set portions from the data sub-blocks; analyze the hashed identifier of each data sub-block to determine whether all data set portions are distributed to the first node device for processing; and in response to a determination that at least one data set portion is to be distributed to a second node device for processing, transmit the at least one data set portion to the second node device.

Systems and methods of the present disclosure are directed to defining a data store format for storing state information related to border-gateway protocol (BGP) routing information base (RIB) entries, BGP Neighbor Tables, intermediate system-intermediate system (IS-IS) adjacencies, Link-State Databases, Interface information, Chassis information, etc in a binary format. A brick data store (BDS) system can define tables, table properties, objects and attributes for an application in the system using configuration files expressed in Java Script Object Notation (JSON). The data format can be uniform across inter-process communication, file and in-memory representation.

A processing apparatus includes a memory, a processor, and a setting processor. The memory has plural memory areas, and the plural memory areas include registered memory areas that are registered to be used, and unregistered memory areas that are not registered to be used. The processor stores input data in a corresponding memory area among the plural memory areas. In response to an instruction to perform a setting process related to a function which uses a memory area, the setting processor executes a setting process including registering a memory area selected from among the unregistered memory areas to use the selected memory area for the function or including presenting the selected memory area to a user as a candidate for the memory area used by the function.

Methods, systems, and computer readable media can be operable to facilitate the updating of memory at a device based upon a custom command file. In embodiments, update or configuration codes or data may be delivered to a device within a download package, and the download package may include a command file. The command file may identify one or more operations that are to be carried out on the memory of the device, and each respective one of the one or more operations may be associated with a subset or portion of the memory of the device. The device may identify the one or more operations and the one or more associated memory areas from the command file, and the device may carry out the one or more operations on only those areas of the device memory that are identified from the command file as being associated with the operations.

Systems and methods for enhancing storage recollection in a shared storage system by enabling the recollection procedure to differentiate between open and abandoned transaction. An example method comprises: detecting, by a processing device, a transaction marker of a storage system, the transaction marker being stored on shared storage and indicating a modification of the shared storage is incomplete; determining, in view of a locking data structure on the shared storage, whether the transaction marker is associated with an abandoned modification; in response to the transaction marker being associated with an abandoned modification, releasing a portion of the shared storage associated with the abandoned modification; and destroying the transaction marker.

A semiconductor memory device according to the present disclosure includes: a memory cell array including a plurality of planes; a command processing unit configured to generate an internal command to be executed by at feast one plane among the plurality of planes on the basis of external commands received from an external controller; a status register configured to store status information of the external commands by a tag included in the external command according to results of performing the internal command.

Certain embodiments described herein relate to an improved block-level replication system. One or more components in an information management system may receive a request to perform a block-level replication between a source storage device and a destination storage device, and depending on the specific replication mode requested, (i) store block-level changes directly to the destination storage device or (ii) first to a recovery point store and then later to the destination storage device.

A memory system includes a nonvolatile memory and a controller. The nonvolatile memory has first regions in which data writes and data reads can be executed in parallel. Each of the first regions has second regions which are each a data write/read unit. The controller acquires first values indicating a data write load for each of the first regions, detects a first region having a first value greater than or equal to a first threshold, acquires second values indicating a data write load for each of the plurality of second regions in the detected first region, detects a second region having a second value greater than or equal to a second threshold but less than or equal to a third threshold that is higher than the second threshold, and then move data from the detected second region to a second region in another first region.

In file storage, a CPU is configured to: divide a file into a plurality of chunks, execute encoding processing on at least one of the chunks to obtain an encoded chunk, and store in cloud storage a plurality of chunks of the file including the encoded chunk; acquire, when receiving a read command of which target is data of a part of a file stored in the cloud storage, a read target chunk including data, which is a target of the read command, from the cloud storage; and execute, when an encoded chunk is included in the read target chunk, decoding processing on the encoded chunk, identify data that is a read target from the read target chunk including the chunk having been subjected to decoding processing, and hand over the identified data to a command source of the read command.

Methods, systems, and devices for multi-stage memory device performance notification are described. A memory system may include a first set of memory cells of a first type associated with a first performance level and a second set of memory cells of a second type associated with a second performance level. The memory system may have an interface and a control circuit coupled with the first and second sets of memory cells. The control circuit may be configured to determine a first parameter associated with a transition between the first performance level and the second performance level. The control circuit may also be configured to store the first parameter in a first register based at least in part on determining the first parameter.
