The present invention provides a system and method for abstracting multiple network attached storage ('NAS') locations, providing a single global namespace and a single mount point that is protocol and location-independent. As a result, rather than identifying each NAS and file server by location, access is provided through a single transparent mechanism. In order to maintain transparency, the present invention provides a way to reconcile the different naming practices for different file server protocols.

Multi-protocol global namespace mechanism for network attached storage

In a storage area network, a task manager identifies a set of preconditions for execution of storage management tasks. The set of preconditions establish dependencies between tasks in the storage area network. Execution of the tasks is contingent upon satisfaction of the set of preconditions. In addition, the task manager generates a scheduling data structure based on the set of preconditions in order to schedule execution of the tasks. As a result, the task manager can utilize the scheduling data structure to optimize task execution in the storage area network (e.g., by applying a task optimization algorithm). Such optimization minimizes resource consumption (e.g., thread allocation, processor time commitment, etc.) in the storage area network during execution of the tasks.

Dependency-based task management using set of preconditions to generate scheduling data structure in storage area network

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.

Separation of presentation and business models for common management platform tasks in a storage area network

Deployment of new elements in a computer network can result in development of patch kits adapters, and other software and trigger corresponding regressive test efforts. In a storage area network, a method is disclosed for defining a general, extensible model of a manageable entity for use in management of the entity. The method includes obtaining a set of attribute values related to the manageable entity in relation to the storage area network. A deployment engine identifies corresponding entity categories within a storage area network entity model that contains attribute definitions that correspond to respective attribute values in the set of attribute values obtained from the manageable entity. The deployment engine assigns the respective attribute values of the manageable entity to the corresponding respective attribute definitions identified in the model. The deployment engine then determines if all attribute values of the manageable entity have been assigned. If unassigned attribute values remain, a classification processor defines new entity categories to contain new attribute definitions, and assigns the unassigned attributes value to the new attribute definitions contained in the new entity category.

Methods and apparatus providing an extensible manageable entity model for a network

A method, system, and program product for reserving resources in a networked environment, e.g. a storage area network. A resource is some object that a user must use or change to complete a task. When a user plans a task, the user selects some high-level resources and properties to reserve and a Reservation Service embodiment creates reservations for them. Accordingly, the method system and program product embodiments overcome inefficiencies in reserving resources in a data storage environment while still allowing such reservations to occur. The method includes reserving portions of properties for resources from more than one available choice.

Accordingly, the method system and program product embodiments overcome inefficiencies in reserving resources in a data storage environment while still allowing such reservations to occur. The method includes selectively reserving properties for resources from more than one available choice.

Described are techniques used in connection with management and processing of configuration data and performance data about a data storage system. The data is collected by one or more agents and forwarded to store components. The store components are responsible for maintaining persistent data objects in a repository. A server may process user requests issued from one or more consoles by retrieving data from the repository and displaying information based thereon on the consoles. The data collected by the agents may be in accordance with a first object model or data representation different from another object model or data representation of the repository. The store components update the repository using data collected by the agents.

System, methods and apparatus operate a module server to service a plurality of different storage area network management modules that each provides a respective type of management functionality for elements operating within a storage area network. The system operates an administration module in conjunction with a module sever. The administration module provides a plurality of module administration interfaces that are software interfaces that can be remotely invoked to administer the plurality of different storage area network management modules. The system receives a remote invocation of at least one of the plurality of module administration interfaces and applies module administration functionality associated with the at least one remotely invoked module administration interface to remotely administer at least one of the storage area network management modules serviced by the module server. By decoupling the administration from the module server, the module server does not need to be shut down to perform module administration and is a less complicated and smaller software process.
