Patent Number: 
Section: claims

1. A device for preparing a captured trace, the captured trace being stored for later use, of I/O workload activity experienced on one or more data storage volumes included with a data storage system for being analyzed by a computerized trace analysis process, the device comprising:a processor in communication with a memory containing software code, which when loaded into said processor enables said processor to execute the steps of:preparing the captured trace for being analyzed by categorizing information from the captured trace into categories related to (i) components in the data storage system experiencing the traced workload activity and (ii) information type including response times and task events;using the categories for access to trace-related information for trace analysis by the computerized trace analysis process; andpresenting the categorized information from the captured trace on a display screen. 2. The device of claim 1, wherein a summary file summarizing the captured trace is created including the categories information and the summary file is used for the access to the trace-related information by the computerized trace analysis process. 3. The device of claim 1, wherein the information type includes I/O activity. 4. The device of claim 1, wherein the components includes logical volume representation of the data storage volumes. 5. The device of claim 1, wherein the computerized trace analysis process includes communication to the computerized trace analysis process for being responsive to the act of a trace being captured.
