摘要:
A storage area network (SAN) has a plurality of components including digital data processors, e.g., hosts, coupled to a plurality of storage device. Common, platform-independent processes execute on the hosts, which can be of varied platform types, e.g., Unix™, Windows™, Solaris, and so forth. Those processes utilizes the command line interface of the host operating system to invoke platform-dependent processes on the respective hosts. The platform-dependent processes return data to the platform-independent processes, e.g., via Standard Output or Standard Error of the host operating system command line interface.

The invention provides, in one aspect, a digital data processing system having an interconnect that provides for registration of components communicating thereon. One or more host devices, storage devices or other components are coupled to the interconnect for communication, at least one of them lacking an ability to self-register with the interconnect. Such a component is referred to herein as a non-compliant component. A registration module coupled with the interconnect performs the registration on behalf of the non-compliant component.

The invention provides improvements on a digital data processing system of the type having a first set of hosts, storage devices or other components coupled for communication with a first network manager. A second set of components is likewise coupled to a second network manager. Communications between the network managers and their respective sets of components utilize different protocols, the first network manager referring to components of the first set with identifiers that are unique to those respective components under the first protocol, and the second network manager referring to components of the second set with identifiers that are unique to those respective components under the second protocol.

A storage area network (SAN) management and configuration method and apparatus are provided via enabling in-band communications. In the storage area network (SAN) management and configuration method, a SAN management application is utilized for communicating with a device driver. A pass through is provided by the device driver to a host bus adapter (HBA) for passing communications to a device in the storage area network from the SAN management application. The storage area network (SAN) management and configuration apparatus via enabling in-band communications includes a storage area network (SAN) management application for communicating with at least one SAN-connected host system. Each SAN connected host system includes a management application agent for communicating with a host bus adapter (HBA) device driver. The HBA device driver is provided for communicating with a device in the storage area network. The HBA device driver includes at least one pass through service for passing a plurality of commands to the device in the storage area network. The management application agent provides predefined protocol functions for communicating with the device in the storage area network. The predefined protocol functions include a common transport (CT) protocol function and an extended link service (ELS) protocol function.
摘要:
A digital data processor of the type used, e.g., in management of a storage area network (SAN), executes a process (a “manager” process) to maintain a representation of the SAN topology or at least an attribute thereof. A graphical output device displays the SAN representation. A further process (a “user interface” process) controls the output device for purposes of displaying that representation. An interface element effects retrieval of the SAN representation, for example, in response to a request from the user interface process. It transmits that representation to the user interface process for display on the graphical output device.

摘要:
A method, system, and computer program product for providing enhanced management features for a SAN with scalable hosts. Partitioned hosts (or ‘scalable’ hosts) are managed by extending SAN manager host-centric logical views to show (1) the host partition hierarchy and (2) the storage resource ownership for a SAN-attached scalable host. The extended host-centric view includes the host system, hosting OSes (if applicable), hosted OSes for each hosting OS (or the host system), OS volumes for each hosted OS, and logical mapping of each OS volume to the SAN storage resource (logical unit). The SAN manager is extended to also show how hosting (trusted) partitions, blades, and/or cluster members physically connect into a SAN. Users are able to toggle between a host centric view and a physical topology view by selection of items within the interface.

An apparatus, system, and method are disclosed for generating a name for a system of devices. An identifier identifies each component in the system. Once each component is identified, information such as the World Wide Name (WWN) of each component is stored in a database. Additional information such as the IP address of each component may also be stored within the database. A comparator then compares a name such as the WWN of each component and selects the name of a selected component based on specified parameters provided by a user. The selected name is modified and then assigned as an identifier of the entire system of devices. The system of devices is thus assigned a unique identifier that remains the same each time those components form a system of devices.
摘要:
A storage area network (“SAN”) includes one or more digital data processors that are coupled for communication with one or more storage devices (e.g., LUNs) over an interconnect. The improvement provides a mechanism for hierarchically displaying, e.g., on the administrator console or other output device, portions of the SAN topology. It includes a process that generates for application to the output device a plurality of graphical object that represent “segments” of the SAN and/or components of the SAN, along with the interconnections between them. The process selectively responds to operator/administrator selection of any of the graphical objects that represent a segment by regenerating the display to depict the interconnected segments and/or components that make up that segment.
