An embodiment of the method includes an autonomous memory device receiving a set of instructions, the memory device executing the set of instructions, combining the set of instructions with any data recovered from the memory device in response to the set of instructions into a packet, and transmitting the packet from the memory device.

Automatic storage system configuration for mediation services that includes: determining that a particular storage system of the storage systems is not configured to request mediation from a mediation target for mediation between storage systems synchronously replicating a dataset; requesting, by the particular storage system from a configuration service, configuration information indicating one or more service handles for a mediation service; and configuring, in dependence upon the one or more service handles received from the configuration service, a mediation handler to communicate with the mediation service responsive to detecting a communication fault with one of the storage systems.

A host device is configured to read and write information from and into a card and to supply a supply voltage that belongs to a first voltage range or a second voltage range which is lower than the first voltage range, and issues a voltage identification command to the card. The voltage identification command includes a voltage range identification section, an error detection section, and a check pattern section. The voltage range identification section includes information indicating which one of the first voltage range and the second voltage range the supply voltage belongs. The error detection section has a pattern configured to enable the card which has received the voltage identification command to detect errors in the voltage identification command. The check pattern section has a preset pattern.

Establishing a synchronous replication relationship between two or more storage systems, including: identifying, for a dataset, a plurality of storage systems across which the dataset will be synchronously replicated; configuring one or more data communications links between each of the plurality of storage systems to be used for synchronously replicating the dataset; exchanging, between the plurality of storage systems, timing information for at least one of the plurality of storage systems; and establishing, in dependence upon the timing information for at least one of the plurality of storage systems, a synchronous replication lease, the synchronous replication lease identifying a period of time during which the synchronous replication relationship is valid.

A method for sending executable content to a first computer is provided. The executable content includes computer instructions. A second computer receives a request from the first computer for contents of an identified disk block that contains a portion of the executable content, the identified disk block being identified by a block parameter that is stored in a data structure at the first computer. Then, the second computer identifies a third computer that includes an application that is available, the application including the disk block within a file structure. The request is provided to the third computer where the third computer uses a mapping between the block parameter and an actual location of the portion of the executable content and sends the portion of the executable content of the identified disk block to the first computer.

Managing storage systems that are synchronously replicating a dataset, including: detecting a change in membership to the set of storage systems synchronously replicating the dataset; and applying one or more membership protocols to determine a new set of storage systems to synchronously replicate the dataset, wherein the one or more membership protocols include a quorum protocol, an external management protocol, or a racing protocol, and wherein one or more I/O operations directed to the dataset are applied to a new set of storage systems.

A computer-readable medium storing instructions which, when executed by at least one processor of a computer system, adapt the computer system to implement a method for displaying relative saturation of a computer disk system. The method includes visually displaying elements of the computer disk system in an infographic disk activity interface. The elements may include at least one of the group including at least one disk controller, at least one physical disk, at least one file, and at least one other files. The elements are visually linked using an arrangement of connectors defining respective data flow paths between the elements. Disk system activity along the data flow paths is visually indicated using static and/or dynamic infographic display elements.

Managing storage systems that are synchronously replicating a dataset, including: detecting a change in membership to the set of storage systems synchronously replicating the dataset; and applying one or more membership protocols to determine a new set of storage systems to synchronously replicate the dataset, wherein the one or more membership protocols include a quorum protocol, an external management protocol, or a racing protocol, and wherein one or more I/O operations directed to the dataset are applied to a new set of storage systems.

Techniques are provided for sharding objects across different compute nodes. In one embodiment, a database server instance generates, for an object, a plurality of in-memory chunks including a first in-memory chunk and a second in-memory chunk, where each in-memory chunk includes a different portion of the object. The database server instance assigns each in-memory chunk to one of a plurality of computer nodes including the first in-memory chunk to a first compute node and a second in-memory chunk to a second local memory of a second compute node. The database server instance stores an in-memory map that indicates a memory location for each in-memory chunk. The in-memory map indicates that the first in-memory chunk is located in the first local memory of the first compute node and that the second in-memory chunk is located in the second local memory of the second compute node.

An electronic device managing method and system, and a host electronic device using the method are disclosed. A plurality of client electronic devices may be connected to the host electronic device. The host electronic device may perform file storage state management, remaining battery capacity management, and file reproduction management, thereby integrally and efficiently managing the plurality of client electronic devices. The file storage state management may include managing file storage states corresponding to the memories of the plurality of client electronic devices, respectively. The remaining battery capacity management may include managing the remaining capacity of the batteries of the plurality of client electronic devices. The file reproduction management may include reproducing at least one of the files stored in the plurality of client electronic devices.
