Abstract: A data management and archive method and apparatus, such as for implementation in an automated system to monitor and manage status, performance and configuration data for a plurality of networked storage components. Analysis and cross-correlation of data related to the plurality of storage components can be done individually, collectively and/or comparatively. A collection manager component of a workload analyzer is implemented to start and stop data collection in the context of a system comprising at least one storage component (or at least two networked storage components). The collection manager includes a command and control module that coordinates requests of data from at least one collection agent configured on at least one host connected to the storage component(s).

The collection manager includes a command and control module that coordinates requests of data from at least one collection agent configured on at least one host connected to the storage component(s). The collection manager manages collection of data and effects file transfer of collected data according to a user specified policy, and maintains status of the data collected.

Abstract: This invention is a system and method for performing a data management function using correlated data obtained from analyzing work performed on data stored in a data storage system.

Abstract: A system provides mechanisms and techniques to retrieve trace data from a trace buffer residing in a data storage system. The software program operating on a processor within the data storage system operates in trace mode to produce trace data in the trace buffer upon occurrence of trace events. An event trace routine operates in response to a system call to access the trace buffer and return either a current value of a trace buffer pointer or the current trace buffer pointer as well as trace data read from the trace buffer beginning at a location and in an amount as specified in the system call to the event trace routine. The trace capture process can operate either within the data storage system or preferably on a remote host computer system to access trace data in the trace buffer in the data storage system by using the event trace routine.

Abstract: This invention is a system and method for replaying workload data that may be accessed in a data storage environment and then replayed for testing or other reasons. The invention has the capability to extract a trace of all I/Os to a data storage system for an extended period of time and then replay these I/Os back to that or another system. Variables may also be manipulated though the play back system to increase testing flexibility at a lower cost than actually introducing new physical variables.
