Saving a capacity of an on-premises storage apparatus, a high access performance of the on-premises storage apparatus, and resuming an operation quickly and accurately by using data on a cloud when a resource in the on-premises fails are achieved. A processor provides a first volume which is a virtual volume, and configures a copy pair of the first volume and a second volume provided from another storage system. Write data to the first volume is transferred to the second volume via a network, based on the copy pair. The processor writes to the memory a part of data written to the second volume, and writes to the storage device the data written to the memory.

A method includes monitoring a job being executed at the source mainframe. A job comprises multiple tasks. A method includes monitoring a particular task of the multiple tasks being executed at a source mainframe and determining an application required to execute the particular task. In response to determining that the particular task requires an application to execute, determining a target mainframe where the application is installed. A method further includes validating the environment of the target mainframe to confirm that the particular task can be executed using the target mainframe, and upon validating the target mainframe, redirecting the particular task to the target mainframe for execution. A method also includes monitoring the particular task being executed at the target mainframe and returning the results of the particular task from the target mainframe to the source mainframe.

A method and/or system for checking the bus/interface between a host and a memory system during memory access operations includes a memory system having one or more of the data memory devices and a spare memory device; providing a bus/interface between a host and the memory system; selecting information on a per memory device basis to associate with a spare memory device; disassociating the selected information from the one or more data memory devices and associating the selected information with the spare memory device; adding Cyclical Redundancy Check (CRC) code to the one or more data memory devices from which the selected information was disassociated; transferring the CRC code and information over the bus and interface between the host and the memory system; and checking the bus interface with the CRC code added to the one or more data memory devices.

A containerized environment and application that are configured for component specific continuous replication and granular application level application. A key value store, which stores key values related to configuration data of the containerized application, is replicated continuously to a replicated key value store at a replica site. Persistent volumes may also be replicated to a replica site. The replication can be performed to multiple replica sites in an application specific manner.

A storage system and method for crash analysis are provided. In one embodiment, a storage system comprises a memory and a controller. The controller is configured to store a crash log in a buffer in the controller; determine whether the storage system has crashed; and in response to determining that the storage system has crashed, send the crash log from the buffer in the controller to a host in communication with the storage system. Other embodiments are provided.

To identify slice errors, a processing module of a computing device in a dispersed storage network (DSN) sends first list digest requests to at least first and second dispersed storage (DS) units. The requests indicates a first range of slice names to include in a first list digest. The processing module receives digest responses from the DS units, and compares the digest responses to determine whether they identify the same slices. If they do not identify the same slices, the processing module sends second list digest requests indicating a sub-range of the first range of slice names to include in second list digests. The sub-range continues to be narrowed until the processing module identifies at least one sub-range of slice names where a slice error exists.

One or more techniques and/or systems are provided for identifying configuration inconsistencies between storage virtual machines across storage clusters. For example, a first storage cluster and a second storage cluster may be configured according to a disaster recovery relationship where user data and configuration data of the first storage cluster are replicated to the second storage cluster so that the second storage cluster can takeover for the first storage cluster in the event a disaster occurs at the first storage cluster. Because replication of configuration data (e.g., a name and size of a volume, a backup policy, etc.) may fail for various reasons, configuration of the first storage cluster is compared to configuration of the second storage cluster to identify a configuration difference (e.g., a new size of the volume at the first storage cluster may have failed to be replicated to a replicated volume at the second storage cluster).

Disclosed embodiments relate to performing updates to Electronic Control Unit (ECU) software while an ECU of a vehicle is operating. Operations may include receiving, at the vehicle while the ECU of the vehicle is operating, a software update file for the ECU software; writing, while the ECU is operating, the software update file into a first memory location in a memory of the ECU while simultaneously executing a code segment of existing code in a second memory location in the memory of the ECU; and updating a plurality of memory addresses associated with the memory of the ECU based on the software update file and without interrupting the execution of the code segment currently being executed in the second memory location in the memory of the ECU.

Apparatuses, systems, and methods related to determination of a match between data values stored by three or more arrays are described. A system using the data values may manage performance of functions, including automated functions critical for prevention of damage to a product, personnel safety, and/or reliable operation, based on whether the data values match. For instance, one apparatus described herein includes a plurality of arrays of memory cells formed on a single memory chip. The apparatus further includes comparator circuitry configured to compare data values stored by three arrays selected from the plurality to determine whether there is a match between the data values stored by the three arrays. The apparatus further includes an output component configured to output data values of one of two arrays of the three arrays responsive to determination of the match between the data values stored by the two arrays.
