Systems and methods for time series data error detection, correction, and transformation may detect gaps and anomalies in time series data, such as from a meter device, and may correct the gaps and adjust the anomalies prior to long-term record storage. Data forecasting may be used to correct the errors in the time series data. The error corrected data may be regarded as an actual set of time series data and become a base data set against which additional heuristic projections are generated. In addition, the time series data may be transformed into any number of physical and virtual device hierarchies that represent the underlying data source configurations, and may then be stored in an analytical database for further analysis. The hierarchies may be irregular and may change over time.

Techniques are disclosed for controlling and managing virtual machines and other such virtual systems. VM execution approval is based on compliance with policies controlling various aspects of VM. The techniques can be employed to benefit all virtual environments, such as virtual machines, virtual appliances, and virtual applications. For ease of discussion herein, assume that a virtual machine (VM) represents each of these environments. In one particular embodiment, a systems management partition (SMP) is created inside the VM to provide a persistent and resilient storage for management information (e.g., logical and physical VM metadata). The SMP can also be used as a staging area for installing additional content or agentry on the VM when the VM is executed. Remote storage of management information can also be used. The VM management information can then be made available for pre-execution processing, including policy-based compliance testing.

A system for write forwarding in a storage environment employing distributed virtualization includes a first and a second storage server providing access to a first and a second physical storage device, respectively, a virtual device server and a virtual device client. The virtual device server may be configured to aggregate storage in the first and second physical storage device into a virtual storage device and make the virtual storage device accessible to the virtual device client for I / O operations. An update requested by the virtual device client may require a first physical write operation at the first physical storage device and a second physical write operation at the second physical device. The virtual device client may be configured to send an update request to the first storage server, rather than to both the first and the second storage servers. The first storage server may respond to the update request by starting the first physical write operation, and forwarding a request for the second physical write operation to the second storage server.

The virtual device receives a response to the request indicative of a status of the computing environment.

A technique efficiently creates and serves a backup data set on a backup filer located at a remote site from a primary filer by essentially moving an entire operating environment of a primary data set to the backup filer. The primary filer is organized into one or more virtual filers (vfilers), one of which (the primary vfiler) is configured to serve data, such as the primary data set, for a client. In the event that the primary filer or primary vfiler becomes unavailable, the technique may be implemented as a disaster recovery or data migration sequence to enable efficient instantiation of a backup vfiler to serve the backup data set for the client.

A peripheral device of a host computer includes a microcontroller and two virtual devices. The first virtual device passes, to the microcontroller, commands of a first command set from any user of the host computer and preferably also commands of a second command set from only privileged users of the host computer.

A system and method for managing disk space in a thin-provisioned storage subsystem. If a number of free segments in a free segment pool at a storage subsystem is detected as below a desired minimum, one or more of the following is performed: selecting and adding logical devices (LDEVs) from an internal storage as free segments to the free segment pool, transitioning LDEVs to a virtual device (VDEV), and / or selecting and adding LDEVs from an external storage as free segments to the free segment pool. The transitioning includes identifying partially used or completely used LDEVs and transitioning these to the VDEV. Data migration may also occur by: selecting a source segment at a VDEV for migration, reading data from the source segment, writing the data to a target segment, the target segment being a free segment from the free segment pool, and assigning the target segment to the VDEV.

A device management manager having a device driver function and communication function installed on the terminal or the like, a virtual device manager having a device driver function and communication function installed on the server, and an authentication server that manages access permission for the device allow the device to be virtually available as in the case of the device directly coupled to the server while managing the access to the device.

Systems, methods, apparatus and software can configure, support, and make use of a coordinator virtual device to determine which node or nodes of a cluster should be ejected from the cluster as a result of a cluster partition or other error event. Fencing software operating on the cluster nodes monitors the cluster for a cluster partition (split-brain) event, and when such an event occurs, software on the nodes attempts to gain control of the coordinator virtual device. A node that succeeds in gaining control of the coordinator virtual device survives. Nodes failing to gain control of the coordinator virtual device remove themselves or are removed from the cluster. The coordinator virtual device can be established by a virtual device configuration server which provides coordinator virtual device access to cluster nodes acting as virtual device configuration clients.

Fitting a sound processing device for an individual is automated using a computer. Fitting and customisation is carried out using natural sounds without specialised audiometric equipment or audiological expertise. Software for this purpose is downloaded from an internet portal. The computer plays back acoustic signals, and obtains user input reflecting the user's perceptions of the acoustic signals, from which a hearing map is derived, representing the user's hearing. An algorithm updates the device fitting based on the hearing map. Also provided is pre-sale virtual device fitting, whereby a virtual signal processing path is established in the computer, reflecting a signal processing function of a sound processing device of interest to the user. An algorithm updates parameters of the virtual processing path, based on the hearing map. Audio signals passed through the virtual processing path are played back to the user, giving the user an acoustic indication of future device performance.

Systems and methods are provided, whereby partitions may become enlightened and discover the presence of a hypervisor. Several techniques of hypervisor discovery are discussed, such as detecting the presence of virtual processor registers (e.g. model specific registers or special-purpose registers) or the presence of virtual hardware devices. Upon discovery, information (code and / or data) may be injected in a partition by the hypervisor, whereby such injection allows the partition to call the hypervisor. Moreover, the hypervisor may present a versioning mechanism that allows the partition to match up the version of the hypervisor to its virtual devices. Next, once code and / or data is injected, calling conventions are established that allow the partition and the hypervisor to communicate, so that the hypervisor may perform some operations on behalf of the partition. Four exemplary calling conventions are considered: restartable instructions, a looping mechanism, shared memory transport, and synchronous or asynchronous processed packets. Last, cancellation mechanisms are considered, whereby partition requests may be cancelled.
