A method is used in managing disk drive power saving in data storage systems. Multiple data storage systems storage elements capable of operating in a power saving mode are identified and grouped into a RAID group. One or more logical units are created from the RAID group. The one or more logical units are exposed to a server. The one or more logical units are associated to an application at the server. Power saving settings are determined. A power saving mode based on the power saving settings is enabled.

Managing disk drive power savings in data storage systems

The subject disclosure is directed towards providing a user with impact-related information regarding the impact of a monitored event (for a detected resource issue) to a managed system, such as a storage system. An event is generated when a resource such as a hard disk has an issue, e.g., has failed. Information from the event is automatically extracted and used to communicate with a management program coupled to the resource. Communication with the management program obtains information as to the impact the resource issue has to the system, e.g., what servers and/or applications are impacted. The impact-related data may be presented in a report to a user.

Monitored system event processing and impact correlation

Described are techniques for processing a request from a client for performing an operation that is received by a business logic provider. First processing is performed by the business logic provider to process the request that includes communicating with other providers for information in connection with the request, performing validation processing using the information obtained from the other providers to determine whether one or more restrictions are violated, each of said one or more restrictions identifying a required state of one or more objects for performing an operation of the request, determining whether any restrictions are violated, and performing one or more actions responsive to determining that any restrictions are violated.

Techniques for performing data validation

Described are methods, systems, and apparatus, including computer program products for locating a target IT component in a data center. A first identification marker is scanned by a mobile computing device. A location of the first identification marker in the data center based on a virtual representation of the data center is determined by the mobile computing device. An identity of the target IT component is received. A location of the rack containing the target IT component in the data center based on the virtual representation of the data center is determined by the mobile computing device. A map of the data center, wherein the map of the data center includes first indicia of the location of the first identification marker and second indicia of the location of the rack containing the target IT component, is displayed by the mobile computing device.

Data center management using virtualized data center inventory

A method is used in managing object deletion. Updated information about a system is repeatedly polled for. An information set is received identifying an object to be deleted from a system management model that is descriptive of the system. An iterative process is applied to determine other objects in the system management model that are unidentified in the information set and that are affected by deletion of the object. The object is deleted.

Managing object deletion

A method is used in mapping data storage and virtual machines. A logical volume from a data storage system is provided for use by a hypervisor. The hypervisor is queried through a web service to identify a virtual machine of the hypervisor. It is determined that the virtual machine is using the logical volume.

Mapping data storage and virtual machines

Described are techniques for processing a request from a client. Validation processing is performed to determine whether any restrictions are violated. With respect to two associated objects for a logical device and its snapshot, a business logical provider may perform runtime checks regarding the two associated objects of the same or different frameworks to ensure a valid state exists with respect to the requested operation on the two associated objects. For example, the request may be to restore a logical device to its previous snapshot and the restrictions may indicate to not perform the restore if the logical device is in an active mirroring relationship, a source of an active migration, or if the snapshot has expired. The request may be to destroy the logical device which is included in a consistency group and a restriction indicates that a logical device included in a consistency group may not be destroyed.

Described are methods, systems, and apparatus, including computer program products for authoring a virtual representation of a data center. An identity of a first IT component is determined. First position data indicating a position of the first IT component in the data center is received. The associated identity of the first IT component and the first position data is stored as a first part of the virtual representation of the data center. An identity of the second IT component is determined. Relative position data indicating a position of the second IT component relative to the first position data is received. Second position data indicating a position of the second IT component in the data center is determined. The associated identity of the second IT component and the second position data is stored as a second part of the virtual representation of the data center.

Authoring a virtualized data center

There is disclosed a technique for use in processing vectorized elements on a mobile computing device. A vector list is received, wherein the list comprises a set of vectors having positional and magnitude values associated with identified markers. A first test angle and stride size is determined. Vectors falling within a boundary defined by the first test angle and first stride size are analyzed and a likelihood the vectors form a line is determined. An increment size is adjusted if a positive determination result occurs. Vectors that intersect with a line are identified, wherein the vectors include vectors determined to fall with the boundary defined by the first test angle and first stride size. Based on a first policy, vectors that intersect the line are identified. A report including anchor information associated with the identified vectors is created.

Processing vectorized elements associated with IT system images

Described are techniques for processing a request received at a business logic provider from a client. The request includes a snapshot identifier uniquely identifying a snapshot having a snapshot object in a first data model and requests properties of a storage device providing a data source for the snapshot identified by the snapshot identifier. The snapshot object is requested from, and returned by, a snapshot provider. The business logic provider requests, from a storage device provider using a first property of the snapshot object, a storage device object corresponding to the storage device identified by the first property. The storage device provider returns the storage device object to the business logic provider. The storage device object is then returned to the client.

Techniques using associated object properties

A method is used in handling managed object data. A software object is created which represents a managed object in a data storage system. The software object holds performance data for the managed object. The software object is created in response to a request for the performance data. Based on a determination that the performance data held by the software object is out of date, the software object is destroyed.

Handling managed object data

There is disclosed a technique executed on a mobile computing device for use in analyzing image data. A heatmap is received, wherein the map comprises data representing a single channel image. A plurality of cache levels are built, wherein each cache level comprises a plurality of zones comprising pixel data, wherein each successive cache level comprises a successively lower resolution and corresponding increase in the number of zones. At each cache level, pixel data is analyzed in each zone beginning with the cache level having the lowest resolution and recursively analyzing each successive cache level. The zone is disabled from further analysis if the zone analysis determines the zone to be empty. The zone is marked for further analysis if the zone analysis determines the zone to be full. Edges associated with pixels in the zone are detected. A vector associated with a marker is created, wherein a vector includes positional and magnitude information and the vector is added to a list of vectors.

Processing image data associated with IT system components

Described are methods, systems, and apparatus, including computer program products for locating one or more markers associated with IT equipment. An image of a scene including the one or more markers is acquired by a mobile computing device. A band-pass filter is applied by the mobile computing device to first pixel data associated with a first pixel in the image to generate a first band-pass filter result, wherein a pass-band of the band-pass filter is based on the light emitted by the one or more markers. A first pixel score is determined by the mobile computing device based on at least the first band-pass filter result. First indicia of the first pixel score is stored by the mobile computing device in a map at a first map location corresponding to a first image location of the first pixel in the image.
