A storage system includes a plurality of nodes connected with a network and configured to provide volumes, a plurality of drive units; and a management system. Each of the plurality of drive units consists of a plurality of storage drives and is accessible from one or more of the plurality of nodes without intervention of the other nodes. The management system or one of the plurality of nodes is configured to determine number of storage drives to be included in a new distribution range to distribute data of a first volume based on access frequency to the first volume.

An apparatus includes a non-volatile memory and a controller coupled to the non-volatile memory. The controller includes a volatile memory configured to store a first copy of a control table associated with the non-volatile memory. The controller is configured to perform a first update of a portion of the first copy of the control table in response to a first request, to initiate a second update of a second copy of the control table at the non-volatile memory based on the first update, and to execute a second request for access to the non-volatile memory concurrently with of the second update. The controller is configured to perform non-blocking control sync operations and non-blocking consolidation operations asynchronously, wherein non-blocking consolidation operations are atomic operations that include concurrent evacuation and compaction of an update layer to a cached address translation table in the volatile memory.

Provided is a linking server that can easily link outputted data with another system. The linking server includes: a communication unit that is capable of communicating between a management server that collects one or more pieces of operating information from one or more image forming apparatus, and an external system that performs processing using the one or more pieces of operating information; a storage unit; an input/output unit that acquires the one or more pieces of operating information that is outputted from the management server, and stores that operating information in the storage unit; and a packaging unit that acquires the one or more pieces of operating information, generates compressed data by performing a compression process and a packaging process, and writes the generated compressed data back into the storage unit; wherein the input/output unit outputs the compressed data to the external system.

An apparatus comprises a processor to receive a plurality of values of a data set, the data set comprising a first value, a second value, and a third value; calculate and store a first delta corresponding to the first value, wherein the first delta is equal to the difference between the first value and the second value; and calculate and store a second delta corresponding to the second value, wherein the second delta is equal to the difference between the second value and the third value.

The present disclosure includes apparatuses and methods for partitioned parallel data movement. An example apparatus includes a memory device that includes a plurality of partitions, where each partition of the plurality of partitions includes a subset of a plurality of subarrays of memory cells. The memory device also includes sensing circuitry coupled to the plurality of sub arrays, the sensing circuitry including a sense amplifier. A controller for the memory device is configured to direct a first data movement within a first partition of the plurality of partitions in parallel with a second data movement within a second partition of the plurality of partitions.

Provided are a computer program product, system, and method for releasing space allocated to a space efficient target storage in a copy relationship with a source storage. Source and target copy relationships indicate source data in the source storage to copy to target data in the target storage. The source copy relationship indicates source data that need to be copied to the target data before being updated, and the target copy relationship indicates target data tracks updated with data copied from corresponding source data. An operation is initiated that results in terminating the source and target copy relationships. Space allocated to the target data for the source and target copy relationships is released in response to determining that the target storage comprises the space efficient storage. The source and target copy relationships are removed.

Provided is an image forming system including an image forming apparatus and a server. The server stores management data. The image forming apparatus accepts an instruction to print in a confidential mode. The image forming apparatus obtains a name of candidate receiver from the server. The image forming apparatus generates a code. The image forming apparatus prints a distribution material including the generated code and the name of candidate receiver corresponding to the generated code. The code is obtained by converting a URL of a site for receipt notification of the distribution material.

A remote data replication method and a storage system, where a production array sends a data replication request to a disaster recovery array. The data replication request includes an identifier of a source object and a data block corresponding to the source object. The data block is stored in physical space of a hard disk of the production array. The disaster recovery array receives the data replication request. The disaster recovery array creates a target object when the disaster recovery array does not include an object having a same identifier as the source object. An identifier of the target object is the same as the identifier of the source object, the disaster recovery array writes the data block into the physical space.

A storage device includes a storage retaining content data, an input receiving instructions to reproduce the content data stored in the storage and a reproducer outputting the content data to an external reproducing device. The storage retains a table including identification information of the external reproducing device and a data format of the content data reproducible in the external reproducing device. The reproducer includes a notifier notifying reproduction information necessary for the external reproducing device to reproduce the content data before the content data are outputted to the external reproducing device in response to a reproduction instruction, and a data controller acquiring unique identification information for the external reproducing device when the external reproducing device is connected to the storage device and converting the content data into the data format reproducible in the external reproducing device and outputting the content data thereto.

Example embodiments of the present invention relate a method, a system, and a computer program product for extent-based tiering for virtual storage using full LUNs. The method includes exposing a virtual LUN comprising a first LUN in a first tier of storage having a first latency and a second LUN in a second tier of storage having a second latency and managing the virtual LUN according to properties of the first LUN, properties of the second LUN, and a policy.
