A method includes, upon a read operation for a stripe of a storage device, determining a percentage amount of potential read amplification for the read operation. A current age of the stripe in the read operation is determined as a percentage of a longest safe elapsed time between read scrub operations on a stripe of the storage device. A read scrub operation is performed on the stripe when the current age is greater than the percentage amount of potential read amplification.

Cost-benefit aware read-amplification in RAID scrubbing

Various embodiments are disclosed for displaying multiple storage windows. One embodiment is a method that displays a first window having a depiction of storage capacity. The first window is expanded to nest two storage windows in the first window.

Displaying multiple storage windows

A method of using a Graphical User Interface (GUI) to display relationships amongst resources of a system can include illustrating at least two overlapping but separate hierarchies in the same mosaic-like graphic, each hierarchy representing one or more of the relationships amongst the resources.

Methods of displaying resources of overlapping but separate hierarchies

Systems and methods for presenting managed data from one or more applications are invented and disclosed. A data storage management system comprises a data store, a data storage manager, and a graphical user interface. The data storage manager is communicatively coupled to the data store and configured to allocate and use logical and physical storage elements of the data store via an application instance. The graphical user interface exposes data storage in application specific storage units. A method for managing data comprises coupling a data store to one or more applications, allocating storage on the data store in accordance with respective storage requirements expressed as an application instance associated with each of the one or more applications, and using a graphical user interface to expose the data store in application storage units associated with the one or more applications.

Systems and methods for presenting managed data

A method generates a graphical portion of a graphical user interface (GUI), the graphical portion concerning aspects of a storage domain. Such a method may include: illustrating a tree hierarchy; including, on the tree hierarchy, a node at a first level corresponding to a set of at least two file systems that are members of the storage domain; and including, on the tree hierarchy, nodes at a second level reporting to the first-level node, each second-level node corresponding to a member of the set of files systems to which the first node corresponds. Related apparatus and machine-readable media having instructions can each include features similar to elements of the method.

Storage domain GUI

The present disclosure relates to a system and method for detecting devices connected to a network. The method comprises sending a scan request to a remote command process running on a remote network host, scanning the network host with the remote command process to determine if devices are connected to the host, and receiving a response to the scan request from the remote command process that indicates whether a device is connected to the network host. In a preferred arrangement, the remote command process sends a scan request to a host application program interface to receive device addresses. With these addresses, the remote command process requests information from the devices.

Device detection system and method

A graphical user interface (GUI) is provided that enables machine control sequences and the results of their execution to be easily and expediently analyzed. Logic is configured to execute GUI generation code and GUI user interaction handling code, and control a display device. When the logic executes the GUI generation code, a first window is displayed on the display device. The first window presents at least one option that enables a user to open a file comprising machine control sequence execution results resulting from execution of a machine control sequence. When the file is opened, a second window is displayed on the display device. The second window displays at least a summary of the execution results comprised in the file.

Method and apparatus for analyzing machine control sequences

A tree-based graphical user interface (GUI) creates and edits command sequences. The GUI simultaneously displays a tree structure and a list. The tree includes a sequence, which is the root node of the tree, at least one step branching from the sequence node, at least one device branching from each step node, and at least one command branching from each device node. When a step node of the tree is selected, the list displays devices that can be added to the step node. When a device node is selected, the list displays commands that can be added to the step. Items can be added or removed from the selected node. The steps, devices, and commands can be configured by selecting the corresponding node in the tree, and by selecting appropriate options on the screens. Operations can be performed absent knowledge of the underlying code and command sequences.
