A task analyzer analyzes received tasks to identify and classify corresponding sub-tasks. For example, for each given received task, the task analyzer analyzes a given task to identify a first type of sub-tasks (e.g., sub-tasks that can be executed in any order). The task analyzer also analyzes the given task to identify a second type of sub-tasks (e.g., sub-tasks that are to be executed in parallel) associated with the given task. A task execution manager submits the first type of sub-tasks for execution by a first pool of processing threads, which is dedicated for executing the first type of sub-tasks. The task execution manager submits the second type of sub-tasks for execution by the second pool of processing threads. The second pool of processing threads is dedicated to execute the second type of sub-tasks.

Task execution using multiple pools of processing threads, each pool dedicated to execute different types of sub-tasks

A task manager (or related operation) keeps track of free processing threads amongst multiple processing threads. The task manager receives a request to execute a task. Prior to execution, the task manager processes the task to identify portions of the task that must be executed in parallel. In response to detecting that there is a first processing thread in the pool free to execute a main portion of the task as well as sufficient free additional processing threads in the pool to execute each of the identified sub-tasks in parallel, the task manager submits the task for execution by the pool of multiple processing threads. For accounting purposes, the task manager modifies tracking information to indicate that the first processing thread and additional processing threads are now unavailable for use for execution of other tasks.

Task management using multiple processing threads

Methods and systems for separating presentation and business models for common management platform tasks in a storage area network (SAN) are disclosed. A graphical user interface (GUI) object may be mapped to a task object, which include action(s) performed on a SAN. A selection of task objects from a collection of task objects is received, which are needed to implement the underlying functionality of a GUI object. The collection of task objects is part of a task framework. An arrangement of the task objects according to a hierarchy of the framework is received. The hierarchy includes simple task objects, corresponding to actions performed on a SAN, and composite task objects, corresponding to at least two simple task objects and may include other composite task objects. The arranged task objects are mapped to the GUI object by extending a presentation object to encapsulate the GUI object and the arranged task objects.
