Abstract: A method for depth mapping includes providing a depth mapping device comprising a projector, which is configured to project a pattern of optical radiation onto a target area over a first field of view about a projection axis, and a camera, which is configured to capture images of the target area within a second field of view, narrower than the first field of view, about a camera axis, which is offset transversely relative to the projection axis. The projector projects the pattern onto first and second planes at first and second distances from the camera, and the camera captures first and second reference images containing first and second parts of the pattern on the first and second planes, respectively. The first and second reference images are combined to produce an extended reference image including both the first and second parts of the pattern.

Abstract: Systems and methods for analyzing the service and performance levels associated with virtual machines in a storage network environment for compliance with a resource capacity policy are provided. Component configuration and connectivity information from components in the network environment is collected without using host agents on the virtual machines. Access paths defining end-to-end access relationships between an application on a virtual machine and storage data objects associated with the virtual machine in the network environment are derived. Access paths comprise sequences of components configured to enable information flow between an application residing on a virtual machine and a data object on a respective storage device. Access path resource consumption is computed and virtual machines with resource consumptions that violate the resource capacity policy are identified.

Abstract: Methods and systems for providing a framework for automated storage processes and flexible workflow are disclosed. The framework provides a user workflow design tool to create and/or customize workflow automation processes without needing to write software code. Additionally, the workflow design tool provides a mechanism that allows the workflow to make decisions, such as selecting storage resources.

Abstract: Methods and systems for collecting, analyzing, and presenting traffic loads in each part of a storage area network are described. These methods and systems account for various resource types, logical access paths, and relationships among different storage environment components. Data traffic flow is managed in terms of resource planning and consumption. The aggregated information is stored, and may be used to estimate future data traffic loads or determine deviations between projected and actual traffic load status from which adjustments may be made to better predict and manage future data traffic load.

Abstract: The systems and methods described herein include processes for efficiently detecting relevant state changes in storage network environments and for resolving the name of hosts in storage networks. A subset of states for each component in the storage network is tracked, state information consisting of the values of the selected states with an associated timestamp and a component identifier (ID) for the storage network components is periodically received, a hash function value of the received state using a pre-selected hash function is computed, the most-recent locally-stored hash function value associated with that component ID is retrieved, and in case the hash function value is different from the most-recently locally-stored value, the new hash function value and the timestamp associated with that new value and component ID are stored and this state information is forwarded to a global analyzer service.

Abstract: Systems and processes for determining and validating accessibility and currency, i.e., the actual status, of data replicated in a networked environment are disclosed. According to the disclosed process, a replicated-data policy for replicating data is defined, and access paths between network devices or between applications running on the network devices are monitored, for example, by a replicated-data monitor. Also monitored are the data replication activities in the network. The currency, i.e., timeliness, and accessibility of a replica by a network device is then compared with the requirements in the replicated-data policy and discrepancies with the replicated-data policy are identified, optionally accompanied by a notification.

Abstract: A dynamic approach for managing capacity in a storage environments accounting for various resource types, tiers, access paths, relationships among different storage environment components, as well as managing capacity in terms of resource planning and consumption is provided. Resource planning and consumption processes are used to allocate and reserve resources of different types and different tiers to each access path in the network. Capacity information for different resources types and tiers is automatically aggregated from different network components at different stages of a resource management cycle. The aggregated information may be used to estimate future resource needs or determine deviations between projected and actual status from which adjustments may be made to better predict future capacity needs.

Abstract: Methods and systems for predictive change management in a network are provided. A configuration change can be specified and pre-validated according to the access path policy, before the actual changes are implemented. The conformance of the implemented configuration change with the access path policy is validated after implementation, because of possible consequential effects of the configuration change. If a change in one or more access paths is specified, then associated component events can be simulated before implementation, so that root causes for resulting access path violations can be detected and remedied before the changes are made.

Abstract: A method and system for constructing and analyzing an access path event history in a network is provided. Inconsistencies in the physical and logical access paths when making changes in the network are detected and analyzed. Component events associated with network appliances are recorded and an event sequence is constructed. Root causes for the inconsistencies are identified and the access paths are repaired in conformance with the network access path policy. The method and systems can be applied to networks in general, and more particularly to storage area networks (SAN).
