The invention relates to a system and method for prioritizing one or more data processing operations in a computer storage system, the computer storage system including a plurality of modules, the method comprising receiving a command indicating one or more data processing operations to which priority is to be assigned and interfacing with each of the modules so as to prioritize the one or more data processing operations over other data processing operations.

Prioritising data processing operations

There is provided a system and a method for increasing input/output ('I/O') throughput in a data storage system. More specifically, in one embodiment, there is provided a method comprising determining an owning controller associated with each of a plurality of storage units of a storage system, receiving an I/O transaction for one of the plurality of storage units, determining if the I/O transaction is a read transaction, and selecting a path to the owning controller associated with the storage unit if the I/O transaction is a read transaction.

System and method for increasing input/output throughput in a data storage system

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.

Diagnosis of a storage area network

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.
