A recording control apparatus configured to access a plurality of recording media, includes a control unit configured to set a temperature threshold of each of first and second recording media, a functional restriction being imposed on the recording medium at the temperature threshold, wherein the control unit is configured to, in recording data read from the first recording medium into the second recording medium, make a first setting for the first recording medium and a second setting for the second recording medium, where the first setting includes setting the temperature threshold of the recording medium at which the functional restriction is imposed on the recording medium to a default value of the recording medium, and the second setting includes setting the temperature threshold of the recording medium at which the functional restriction is imposed on the recording medium to a value greater than the default value of the recording medium.

A storage network processing system includes a processor, a network interface and memory that stores operational instructions. The operation instructions enable the processor to receive a data object for storage and dispersed error encode the data object in accordance with dispersed error encoding parameters to produce a plurality of encoded data slices. The operation instructions further enable the processor to generate to determine a plurality of site slice sets from the plurality of encoded data slices, where each site slice set of the plurality of site slice sets includes a number of unique encoded data slices of the plurality of encoded data slices that is greater than or equal to a site write threshold value. The operation instructions further enable the processor to a designate one of a plurality of storage sites for each of the plurality of site slice sets and transmit each of the plurality of site slice sets to a corresponding designated one of the plurality of storage sites via the network.

The present disclosure includes apparatuses and methods for data movement. An example apparatus includes a memory device that includes a plurality of subarrays of memory cells and sensing circuitry coupled to the plurality of subarrays. The sensing circuitry includes a sense amplifier and a compute component. The memory device also includes a plurality of subarray controllers. Each subarray controller of the plurality of subarray controllers is coupled to a respective subarray of the plurality of subarrays and is configured to direct performance of an operation with respect to data stored in the respective subarray of the plurality of subarrays. The memory device is configured to move a data value corresponding to a result of an operation with respect to data stored in a first subarray of the plurality of subarrays to a memory cell in a second subarray of the plurality of subarrays.

A computer system stores metadata that is used to identify physical memory devices that store randomly-accessible data for memory of the computer system. In one approach, access to memory in an address space is maintained by an operating system of the computer system. Stored metadata associates a first address range of the address space with a first memory device, and a second address range of the address space with a second memory device. The operating system manages processes running on the computer system by accessing the stored metadata. This management includes allocating memory based on the stored metadata so that data for a first process is stored in the first memory device, and data for a second process is stored in the second memory device.

A memory system includes a controller, a buffer, and a nonvolatile memory including a plurality of blocks, wherein each of the blocks includes a plurality of pages and each of the pages includes a plurality of unit data portions. The controller is configured to carry out garbage collection by reading data from one or more pages of a target block of the garbage collection and selectively copying valid unit data portions included in the read data to another block, count a number of invalid unit data portions included in the read data, and accept, in the buffer, unit data portions from a host as write data, up to a number determined based on the counted number, during the garbage collection.

A method performed by one or more processors comprises displaying code, receiving user selection of a portion of code, determining one or more settable data items, generating a template, displaying the template, receiving a user input value for the settable data items by the template, and executing the code with each of the settable data items set to the received user input value. A data processing pipeline is configured to pass a data item to a first transformer to provide first transformed data, store the first transformed data in a temporary memory, write the first transformed data to the data storage system, and pass the transformed data from the temporary memory to a second transformer.

The disclosure relates in some aspects to managing the fetching and execution of commands stored in submission queues. For example, execution of a command may be blocked at a data storage apparatus due to an internal blocking condition (e.g., a large number of commands of a particular type are pending for execution at the data storage device). As another example, execution of a command may be blocked at a data storage apparatus due to an external blocking condition (e.g., a host device may specify that certain commands are to be executed immediately one after another). The disclosure relates in some aspects to controlling how commands are fetched and executed so that commands that cannot be executed by the data storage apparatus in the near future do not prevent other commands (that are not subject to the same blocking condition) from being executed.

An information processing apparatus reads definition information that is common to a plurality of magnetic tapes and defines a plurality of pieces of data included in archive data, generates the same number of pieces of the archive data as the number of the magnetic tapes based on the definition information, the archive data being obtained by grouping the plurality of pieces of data, and performs control of recording the plurality of pieces of generated archive data on the plurality of magnetic tapes in one-to-one correspondence.

A method may include accessing, by a first apparatus, a queue, wherein the queue may be accessible by a second apparatus, and the first apparatus may be connected to the second apparatus by a coherent interface, and indicating, by the coherent interface, to the second apparatus, the accessing. The indicating may include indicating by a monitoring mechanism. The indicating may include generating a monitoring request. The indicating may include generating, based on the monitoring request, an alert. The queue may include a submission queue. The queue may include a completion queue. The accessing may include reading an entry from the queue. The accessing may include writing an entry to the queue. The entry may include a command. The entry may include a completion. The first apparatus may include a host, and the second apparatus may include a device. The queue may be located at the host.

An edge accelerator card has a first interface, a second interface, a memory and a processor. The first interface is to couple to a server. The second interface is to couple to a storage system. The processor is to handle communication between the server and the storage system through the first interface and the second interface. The processor is to perform at least one task as directed by the storage system, using the memory and communication through at least the second interface.
