In a method for managing an image of a container in a host device, a first image of a first container is received, wherein the first image includes a first set of image layers for implementing a first set of services of the first container respectively. The first image is loaded to deploy the first container at the host device. Based on an attribute of an image layer in the first set of image layers, an expiration time is set for the image layer. In response to determining that the expiration time is reached, the image layer is deleted from the host device. Stored image layers can be reused to reduce the transmission bandwidth for remotely downloading the image layers. A corresponding device and a corresponding computer program product are provided.

This disclosure provides techniques hierarchical address virtualization within a memory controller and configurable block device allocation. By performing address translation only at select hierarchical levels, a memory controller can be designed to have predictable I/O latency, with brief or otherwise negligible logical-to-physical address translation time. In one embodiment, address transition may be implemented entirely with logical gates and look-up tables of a memory controller integrated circuit, without requiring processor cycles. The disclosed virtualization scheme also provides for flexibility in customizing the configuration of virtual storage devices, to present nearly any desired configuration to a host or client.

A system and method for visualizing multiple datasets in a virtual 3-dimensional interactive environment. Multiple datasets may be related and virtually cast as 3-dimensional type structures. User interfaces, such as game controllers or headsets, may be used to present the dataset from differing perspectives including the appearance of moving through the data. Certain embodiments provide for mirror image views that allow for presentation of higher order datasets. Other embodiments provide for animation or motion indicia to show how the data is changing and the results on the display. The datasets may represent physical areas or virtual areas as well as demographic, sensors and financial information.

A method for preserving a media access control (MAC) address of a virtual server is provided. The method includes assigning a physical computing resource to a virtual server, assigning a physical storage memory resource to the virtual server, and assigning a physical network resource to the virtual server. The method includes assigning a virtual MAC address to the virtual server, the virtual MAC address to remain with the virtual server despite reassignment of one or more of the physical computing resource, the physical storage memory resource or the physical network resource, wherein at least one method operation is performed by a processor. A computing and storage system is also provided.

A system and method for the dynamic, run-time configuration of logic core register files, and the provision of an associated execution context. The dynamic register files as well as the associated execution context information are software-defined so as to be virtually configured in random-access memory. This virtualization of both the processor execution context and register files enables the size, structure and performance to be specified at run-time and tailored to the specific processing, instructions and data associated with a given processor state or thread, thereby minimizing both the aggregate memory required and the context switching time. In addition, the disclosed system and method provides for processor virtualization which further enhances the flexibility and efficiency.

A method of data reduction in a partially encrypted volume includes receiving data to be stored on a storage array, decrypting the data using a first encryption key to generate first decrypted data, and decrypting the data using a second encryption key to generate second decrypted data. The method further includes comparing, by a storage array controller, a first compressibility value of the first decrypted data to a second compressibility value of the second decrypted data. The method further includes storing the first decrypted data if the first compressibility value is greater than or equal to the second compressibility value. The method further includes storing the second decrypted data if the second compressibility value is greater than the first compressibility value.

It is described an electronic device, comprising a secure element domain that further comprises: i) a physical memory region configured to store a plurality of data sets; and ii) a control device, coupled to the physical memory region, and configured to transfer at least one data set away from the physical memory region, wherein transferring the data set comprises at least one of: a) transferring the data set as a first data blob to a virtual memory region of the secure element domain; b) off-loading the data set as a second data blob to an external domain.

A node interconnection apparatus includes a computing node, a resource control node, and a device interconnection interface connecting the computing node and the resource control node. Each of the computing node and the resource control node includes a processing unit and a storage unit, and the resource control node further includes a resource interface for connecting with a network storage device. The resource control node manages a storage resource of the network storage device, and when the computing node needs to start up, the resource control node obtains operating system startup information from the network storage device and provides the operating system startup information to the computing node. The computing node can start up without the need for storing startup information locally.

Calculating storage consumption in a storage-as-a-service model, including: identifying a data object stored in a pool of storage resources, wherein the pool of storage resources are accessible by a plurality of entities and the data object occupies an amount of storage capacity within the pool of storage resources; attributing to each entity a fractional portion of the amount of storage capacity occupied by the data object; and calculating, in dependence upon the fractional portion of the amount of storage capacity occupied by the data object and attributed to a particular entity, a storage cost for the particular entity.
