摘要:
An apparatus, system, and method are disclosed for detecting entity changes in a storage area network. A discovery module probes a plurality of entities of the storage area network to detect an event in response to a policy, stores attributes of the probed entities, and reports the event with a probe event reference. A monitor module receives a self-announced event reference of the event if an entity communicates the event. A configuration module records the event as an initiated event reference if the event is initiated by an administrator. An event manager synthesizes a report of the event from the event references.

A method, system, and computer program product for implementing policies in a managed systems environment is provided. A plurality of the heterogeneous entities is organized into a system resource group (SRG). Each of the plurality of heterogeneous entities is visible to an application operable on the managed systems environment. The system resource group is subject to at least one membership requirement, defines a relationship between at least two of the heterogeneous entities, contains at least one policy defining an operation as to be performed on the system resource group for a domain of the managed systems environment, and defines at least a portion of a policy framework between the system resource group and an additional system resource group organized from an additional plurality of the heterogeneous entities. The system resource group expands according to an action performed incorporating the relationship, policy, or policy framework.

Policies are implemented in a managed systems. Virtual heterogeneous entities are organized into a system resource group (SRG) hosted on a virtual volume that is accessed via a virtualization machine. Each of the virtual heterogeneous entities are visible to an application operable on the managed systems environment. The system resource group is subject to at least one membership requirement, defines a relationship between at least two of the virtual heterogeneous entities, contains at least one policy defining an operation as to be performed on the system resource group for a domain of the managed systems environment, and defines at least a portion of a policy framework between the system resource group and an additional system resource group organized from additional virtual heterogeneous entities. The system resource group expands according to an action performed incorporating the relationship, policy, or policy framework.

A SAN management system including the ability to generate perspectives of a SAN topology is provided. The SAN management system includes a SAN manager program to monitor a SAN. The SAN management system further includes a SAN management database linked with the SAN manager program, wherein the SAN management database maintains information identifying devices included within the SAN and connections between the devices. In addition, the SAN management system includes a plurality of sensor agents positioned within the devices included within the SAN, wherein the sensor agents gather information pertaining to the connections between the devices and provide the gathered information to the SAN manager program for inclusion within the SAN management database. Moreover, the SAN management system includes a topology viewer linked to the SAN manager to generate a user requested topology perspective according to data included within the SAN management database and data associated with a previously requested topology perspective.
摘要:
A detectibility service for a storage infrastructure manager (SIM) operating on a storage area network (SAN) is disclosed directed to addressing a situation where there may be multiple sources of duplicate or contradictory information to the SIM about the presence and condition of an element in the SAN. The service can account for both authoritative as well as nonauthoritative sources of information in a SAN, which participate in the discovery process scanning for SAN elements. Both authoritative and nonauthoritative sources of information can be used to report a given SAN element during a probe, taking advantage of the more efficient processing of information from authoritative sources to override information from nonauthoritative sources regardless of the order in which the various scans may occur.

摘要:
Data collection agents are assigned to storage area network nodes in a storage area network resource management system, such that the bandwidth and cost of data collection are equitably distributed among data collection agents. Data collection overlaps and load imbalances are eliminated across the data collection agents, creating approximately equal partitions of bandwidth and data collection for each data collection agent. Graph partitioning is used to accomplish load balancing. The assignment of data collection agents to storage area network nodes equitably distributes the bandwidth and processing costs among the data collection agents and ensures a load balance.

A method, system, and article are provided to enable a Hyperswap operation in a clustered computer system. Each node in the system is configured with flash memory, with a hierarchical list of boot volumes therein. Following a Hyperswap operation, the current boot volume is communicated to each node in the cluster and each node joining the cluster. All previously inactive nodes that were booted from the improper boot volume are re-booted from the correct and the flash memory is amended to reflect the correct boot volume.
