Abstract: 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.

Abstract: An apparatus, system, and method are disclosed for dynamically adjusting performance monitoring of storage area network (“SAN”) components. An initial violation module is included to determine that a threshold violation associated with a SAN component is an initial threshold violation. A violation entry module is included to record a component violation entry in response to the initial threshold violation. An entry adjustment module is included to adjust a component violation entry associated with a SAN component in response to a threshold violation related to the SAN component. An analysis module is included to analyze the component violation entry based on analysis criteria. A suspicion adjustment module is included to adjust a suspicion variable associated with the SAN component in response to results of the analysis of the component violation entry.

Abstract: An apparatus, system, and method are disclosed for dynamically determining a set of Storage Area Network (SAN) components for performance monitoring. The computer program product monitors SAN components of a predefined set of SAN components according to a monitor data structure associated with each SAN component. At least one attribute of the set of SAN components is changed in response to a threshold violation by a SAN component in the set. The SAN components of the changed set are monitored according to the monitor data structure for each SAN component within the changed set as part of a monitoring feedback loop.

Abstract: Novel storage area networks (SANs) and methods of operation thereof utilize a plurality of hosts coupled via an interconnect with one or more storage units. A manager device, process or other functionality in communication with a plurality of agent processes, devices or other functionality, each of which is associated with a host. The agents identify attributes of (i) their associated hosts, (ii) interconnect to which that host is coupled, and/or (iii) storage units to which that host is coupled via the interconnect. The manager responds to these attributes identified by the agents to manage the SAN. The manager can be implemented on a first digital data processor and the hosts on further digital data processors. These digital data processors can be coupled via a first network, e.g., an IP or other network, to support communications between the manager and the agents. A second network, e.g.
