摘要： A SAN testing application may be provided to restrict the utilization of one or more SAN device resources. The restricted, or throttled, resource(s) enables a smaller load to stress a SAN switch to effectively emulate a larger load. Resource throttling may, for example, result in the rapid filling of switch buffers and corresponding computational stress. The emulated load allows for all ports of a SAN switch to be simultaneously tested without the need or expense of a large number computing devices stressing the SAN. The SAN device with throttled resource(s) may be located within a testing environment or may be located in a functioning SAN to determine SAN bottlenecks prior to critical loading.

摘要： Techniques to simulate production events are described. Some embodiments are particularly directed to techniques to simulate production events based on randomization across a distribution of production events. In one embodiment, for example, an apparatus may comprise a simulation application operative to simulate one or more commands in a simulated environment using a task hierarchy, the simulation application comprising a configuration component, a command generation component, and an execution component, wherein simulating the one or more commands comprises executing one or more task commands. The configuration component may be operative to receive the task hierarchy from the data store, the task hierarchy comprising a plurality of task entries, each task entry comprising a list of task entries or a task command, the list of task entries comprising probabilities associated with each task entry in the list of task entries, wherein task commands correspond to the simulated environment representing a production environment. The command generation component may be operative to determine the one or more task commands by traversing through the task hierarchy based on the associated probabilities until the one or more task commands are reached. The execution component may be operative to execute the one or more task commands as one or more simulated commands in the simulated environment. Other embodiments are described and claimed.

摘要： Methods, devices (such as computer readable media), and systems (such as computer systems) for performing movements of a tool of a medical robot along a single axis that are achieved by electronically limiting the medical robot's movement to produce movement of the tool along the single axis rather than mechanically restricting the medical robot's movement to produce the single axis movement. The tool's movement will be along the single axis even if a user is moving an input device linked to the medical robot in other axes during the single axis movement. In addition, techniques are disclosed for automating the single axis movement such that it can be programmed to stop at a target location and start at or near a second (e.g., starting) location, which is useful for a procedure such as a brain biopsy, breast biopsy or implantation, and such that a user can execute a command instructing the medical robot to perform the movement without the need for the user to manipulate an input device to cause real-time responsive movement of the medical robot.
