An exemplary communication method and system is disclosed. The system may be configured to create a mesh network of nodes for routing and/or rerouting data communications depending on the integrity of or demands on the system to improve efficiency and transmission confidence. The system may be configured to redundantly, simultaneously send data transmissions on different transmission interfaces using different transmission protocols.

Systems, apparatuses, and methods related to media management, including “garbage collection,” in memory or storage systems or sub-systems, such as solid state drives, are described. For example, a criticality value can be determined and used as a basis for managing a garbage collection operation on a data block. A controller or the system or sub-system may determine that a criticality value associated with performing a garbage collection operation satisfies a condition. Based on determining that the condition is satisfied, a parameter associated with performing the garbage collection operation can be adjusted. The garbage collection operation is performed on the data block stored on the memory component using the adjusted parameter.

Aspects of the present disclosure relate to data deduplication (dedup) techniques for storage arrays. At least one input/output (IO) operations in an IO workload received by a storage array can be identified. Each of the IOs can relate to a data track of the storage array. a probability of the at least one IO being similar to a previous stored IO can be determined. A data deduplication (dedup) operation can be performed on the at least one IO based on the probability. The probability can be less than one hundred percent (100%).

A memory system includes a plurality of memory devices and a controller, wherein each of the plurality of memory devices includes zone blocks. The controller is configured to evenly distribute open zone blocks within the memory devices by referring to an activated zone block count table and a full zone block count table. The activated zone block count table includes an activated zone block count of each of the memory devices, and the full zone block count table includes a full zone block count of each of the memory devices.

Systems and methods are disclosed for managing workload among server clusters is disclosed. According to certain embodiments, the system may include a memory storing instructions and a processor. The processor may be configured to execute the instructions to determine historical behaviors of the server clusters in processing a workload. The processor may also be configured to execute the instructions to construct cost models for the server clusters based at least in part on the historical behaviors. The cost model is configured to predict a processor utilization demand of a workload. The processor may further be configured to execute the instructions to receive a workload and determine efficiencies of processing the workload by the server clusters based at least in part on at least one of the cost models or an execution plan of the workload.

A system and method for encoding data using a plurality of encoding libraries. Portions of the data are encoded by different encoding libraries, depending on which library provides the greatest compaction for a given portion of the data. This methodology not only provides substantial improvements in data compaction over use of a single data compaction algorithm with the highest average compaction, but provides substantial additional security in that multiple decoding libraries must be used to decode the data. In some embodiments, each portion of data may further be encoded using different sourceblock sizes, providing further security enhancements as decoding requires multiple decoding libraries and knowledge of the sourceblock size used for each portion of the data. In some embodiments, encoding libraries may be randomly or pseudo-randomly rotated to provide additional security.

The present disclosure includes apparatuses and methods related to hybrid memory management. An example apparatus can include a first memory array, a number of second memory arrays, and a controller coupled to the first memory array and the number of second memory arrays configured to execute a write operation, wherein execution of the write operation writes data to the first memory array starting at a location indicated by a write cursor, and place the write cursor at an updated location in the first memory array upon completing execution of the write operation, wherein the updated location is a next available location in the first memory array.

A distributed data storage system using erasure coding (EC) provides advantages of EC data storage while retaining high resiliency for EC data storage architectures having fewer data storage nodes than the number of EC data-plus-parity fragments. An illustrative embodiment is a three-node data storage system with EC 4+2. Incoming data is temporarily replicated to ameliorate the effects of certain storage node outages or fatal disk failures, so that read and write operations can continue from/to the storage system. The system is equipped to automatically heal failed EC write attempts in a manner transparent to users and/or applications: when all storage nodes are operational, the distributed data storage system automatically converts the temporarily replicated data to EC storage and reclaims storage space previously used by the temporarily replicated data. Individual hardware failures are healed through migration techniques that reconstruct and re-fragment data blocks according to the governing EC scheme.

A new type of instruction and a control register for the new type of instruction are provided to handle data that may be misaligned in memory. A first part of data (which may be misaligned in memory) is loaded into a first set of registers by loading a first atom containing the first part of data into registers. The pack instruction is executed by an execution unit to place part of data (whose length and starting position are indicated by second and third values in a control register) from one set of registers into an identified location (identified by a first value in the control register) in another set of registers.

A storage device including: a memory storing data based on program modes; and a storage controller including a program mode table, the storage controller configured to: in response to a program request and first data being already stored in the memory, perform a deduplication operation in which the first data is logically and not physically programmed, in response to the program or an erase request, update a count value from a first to a second value, and in response to a determination that a first program mode corresponding to the first value and a second program mode corresponding to the second value are different, transmit a first command and address to the memory such that a first program operation in which the first data programmed with first bits corresponding to the first program mode is re-programmed with second bits corresponding to the second program mode is performed,
