The present disclosure relates to a method and system for presenting a set of control functions via an interface of a peripheral control device (PCD). A control function can include a command associated with one or more media contexts of a host media device. The method decodes a payload, from the host media device, with an encoded context identifier, where the context identifier indicates a primary media context active on the host media device. The method determines one or more control functions corresponding to the context identifier, and changes the set of control functions on the interface of the PCD to include the one or more control functions that can command the primary media context.

Method and apparatus for peripheral context management

A set of data chunks stored in a first data storage system is accessed. The set of data chunks includes original data chunks and replicated data chunks respectively corresponding to the original data chunks. A given original data chunk and the corresponding replicated data chunk are stored in separate storage nodes of the first data storage system. For each of at least a subset of storage nodes of the first data storage system, unique ones of the original data chunks and the replicated data chunks stored on the storage node are aggregated to form a data object. The data objects thereby formed collectively represent a given data volume. Each of the data objects is stored in separate storage nodes of a second data storage system.

Data archiving in data storage system environments

Techniques are disclosed for managing workloads across a distributed virtual infrastructure. In one example, a method comprises the following steps. Information is collected relating to services offered by service providers across a multi cloud environment implemented in accordance with a distributed virtual infrastructure. A service capability model is maintained based on the collected information. Service level claim conformance is validated for the services offered by the service providers. One or more recommendations are generated based on the collecting, maintaining and validating steps for presentation to a subscriber to assist in management of one or more workloads across the multi cloud environment.

Workload management in multi cloud environment

Techniques are disclosed for measuring and attesting to service levels offered by a service provider in a computing system implemented with a distributed virtual infrastructure. In one example, a method comprises the following steps. Information is maintained relating to one or more services offered by one or more service providers in accordance with a distributed virtual infrastructure. One or more service level claims associated with the one or more services are validated. A subscriber is sent validation results for at least a portion of the one or more services.

Cloud service level attestation

Information processing techniques are disclosed for managing knowledge across a distributed entity. For example, a method comprises the following steps. A database of information is maintained representing knowledge attributable to at least one distributed entity. An interface is provided for presenting at least a portion of the information maintained in the database and for presenting one or more responses to one or more queries to the database. At least a portion of the one or more responses is indicative of at least one of an expansion, a transfer and a leveraging of the knowledge attributable to the at least one distributed entity.

Knowledge management across distributed entity

A method and system for initializing a Network Attached Storage (NAS) system having disaster recovery capabilities uses a communication link disposed between control stations of a source and destination NAS to enable the destination NAS to consolidate configuration and mapping information at a centralized location, thereby enabling validation of disk mirroring and mapping of standby components to be performed in a consistent manner.

System and method for initializing a network attached storage system for disaster recovery

A system, architecture for initializing and utilizing a mirrored Network Attached Storage (NAS) system is described. The architecture includes a plurality of processing layers that define and control the operation and relationship of component groups in a primary NAS and associated component groups in a secondary NAS. The groups may include, for example, file server groups and disk device groups. The processing layers may include an execution layer, a transaction layer and a storage layer. The modularized architecture of the invention allows NAS systems to be easily apportioned into logical groups at varying levels of granularity with varying relationships. As a result, the component groups are abstracted from their underlying physical characteristics and constraints, thereby enabling complex processes such as initialization, activation and restoration to be performed using simple commands at a command line interface.

Disaster recovery using mirrored network attached storage

In an asynchronous remote copy system, a primary site keeps a list of data blocks for which changes have been made to a primary file system and transmitted to a secondary file system at a secondary site. When the primary site becomes inoperative, the secondary site begins read/write access to the secondary file system and keeps a snapshot copy of the restart point. Once the primary site becomes operative, the primary file system is restored to the state of the secondary file system at the restart point by using the list of data blocks for obtaining from the snapshot copy the data of the blocks for which changes had been made to the primary file system after the restart point. Then the primary file system is synchronized to the secondary file system, and read/write access is switched back from the secondary file system to the primary file system.
