摘要： A system and method of input/output (I/O) workload analysis of the components in a storage area network (SAN) are disclosed. In one embodiment, I/O workloads of components in the SAN are analyzed by determining host bus adapter (HBA) port to storage port oversubscription ratios as well as HBA port to inter-switch link (ISL) oversubscription ratios. A subset of the components for monitoring based on the HBA port to storage port oversubscription ratios and the HBA port to ISL oversubscription ratios is selected. The subset of the components is continuously monitored and the I/O statistics of the subset of the components are stored. Expected I/O workloads of the subset of the components are forecast based on current I/O workloads associated with the I/O statistics of the subset of the components and respective I/O workload threshold values of the subset of the components.

摘要： A method of determining a state of a Storage Area Network SAN is provided comprising analyzing data collected from components in the SAN, calculating a redundancy level of the SAN based on the analyzed data, and determining the state of the SAN based on the calculated redundancy level. The redundancy levels indicate the sensitivity of the SAN to a fault in one of the components. The method also includes receiving user policy settings allowing automatic correction of the SAN and auto-correcting the SAN in response to a change in the SAN state and in dependence on the user policy settings. The redundancy levels can be used by an administrator to set the user policy settings. An apparatus for carrying out the method is also provided.

摘要： A method and system for visualizing a SAN is disclosed. In one embodiment, a method for visualizing a SAN includes scanning SAN components in the SAN to determine respective types of the SAN components and connectivity information between the SAN components. The method also includes generating a hierarchically-laid-out SAN graph by determining respective positions of the SAN components in the SAN based on the types of the SAN components and the connectivity information. The method further applying a force-directed model to the hierarchically-laid-out SAN graph to generate a SAN topology layout, wherein attractive and repulsive forces between the SAN components are tuned based on the types of the SAN components and the connectivity information. In addition, the method includes displaying the SAN topology layout on the display area of a display device in a management station coupled to the SAN.

摘要： A method, system and computer program product for migrating at least one switch in a storage area network is disclosed. The migration is done by analysing the I/O traffic to identify patterns in the I/O traffic of the switch; forecasting future I/O workload of the switch based on one or more identified patterns in the I/O traffic, determining appropriate timing for migration based on the identified patterns and administrator inputs; processing the storage area network configuration data to identify the storage network physical and logical access paths to the or each selected switch to create a first connectivity map; generating a second connectivity map based on the first connectivity map and administrator inputs; and migrating the or each switch migration based on the second connectivity map and the appropriate timing. The migration may comprise routing the I/O traffic from the switch to be migrated to the alternate switches in the storage area network. The migration may further comprising transforming zones on the switch to be migrated and deploying the transformed zones to the new switch
