The variable “n” indicates that there are any number of storage systems in the storage network 100. Storage manager 106 communicates with the storage systems 2001, 2002, 2003 . . . 200n over the network 104 to gather performance metrics on the components of the storage systems 2001, 2002, 2003 . . . 200n to store in a performance metrics database 110, such as response times (e.g., overall response time, read response time, write response time), I/O rate (e.g., write I/O rate, read I/O write, overall read rate), cache percentage (overall read cache hit percentage, overall write cache hit percentage, overall cache hit percentage, etc.), transfer rate at which read and write data is transferred, transfer size of read and write data transferred, etc.
The storage manager 106 includes a storage performance manager 108 comprising a program module to gather the metric data from the storage systems 2001, 2002, 2003 . . . 200n and to store in the performance metric database 110 to gather performance metric values.
FIG. 2 illustrates an embodiment of components in a storage system 200, such as one of the storage systems 2001, 2002, 2003, . . . , 200n. The storage system 200 includes configured storage resources 204 comprising logical storage space configured in physical storage devices 202 that is allocated for use or management, including volumes 206, storage pools 208, storage arrays 210 (e.g., Redundant Array of Independent Disks (RAID), Direct Access Storage Device (DASD), managed disks, etc), and I/O groups 212, among others. The storage system 200 further includes computational resources 214, such as controllers 216, nodes 218, such as processing nodes, ports 220 for communication with the physical storage devices 202 and the network 104, and performance metric information 222. The controllers 216 may gather performance information with respect to configured storage resources 202, computational resources 214, and storage devices 202, such as overall, read and write statistics including response times, I/O rate, data rate, transfer size, cache percentages, etc. The metrics information 222 may further indicate a time the data was gathered.

FIG. 3 illustrates an embodiment of performance metric information 300 maintained in the performance metric database 110, including a storage system identifier 302; an identifier of a component 304 in the storage system 302 for which the performance metric values 3061, 3062 . . . 306n are gathered, such as a unique identifier of any of the configured storage resources 204, storage devices 202, and computational resources 214; and values for one or more performance metrics 3061, 3062 . . . 306n gathered for the component 304, including by way of example, but not limited to, response times (e.g., overall response time, read response time, write response time), I/O rate (e.g., write I/O rate, read I/O write, overall read rate), cache percentage (Overall read cache hit percentage, overall write cache hit percentage, overall cache hit percentage, etc.), transfer rate at which read and write data is transferred, transfer size of read and write data transferred, etc.
FIG. 4 illustrates an embodiment of operations performed by the storage performance manager 108 to provide a series of graphical user interface (GUI) panels, as shown in FIGS. 5, 6a, 6b, and 6c to enable a user to select options to generate performance reports, as shown in FIGS. 7 and 8, that compares performance metrics across storage systems 2001, 2002, 2003 . . . 200n. Upon initiating (at block 400) performance metric report generating, the storage performance manager 108 generates (at block 402) a storage system selection GUI enabling selection from indication of a plurality of storage systems 2001, 2002, 2003 . . . 200n for which information 300 is maintained in the performance metric database 110. FIG. 5 illustrates an example of a storage system selection GUI 500 having a drop down menu 502 from which the user may select one of the displayed storage systems 2001, 2002, 2003 . . . 200n, where the selected storage systems are shown as highlighted.
Upon receiving (at block 404) selection of selected storage systems from the rendered indication of storage systems in the storage system selection GUI 500, the storage performance manager 108 determines (at block 406) from the performance metric database 110 performance metrics common to the selected storage systems. This may be determined from the performance metric information 300 for the selected storage systems 300 that are common among all the selected storage systems 2001, 2002, 2003 . . . 200n. The storage performance manager 108 generates (at block 408) a performance metric selection GUI enabling selection of the determined performance metrics common to the selected storage systems, selection of a time interval at which the performance metric values are sampled, and selection of a reporting period over which the performance metrics are sampled at the time intervals.
FIGS. 6a, 6b, 6c illustrate examples of the performance metric selection GUI 600a, 600b, 600c for storage systems showing different categories of selected performance metrics 602 common to the selected storage systems that may be selected. A drop down menu 604a in FIG. 6a is displayed showing the different common performance metric types for the selected components, such as cache percentage, data rate, I/O rate, response time, and transfer size. The performance metric selection GUIs have the selected performance metrics 606 selected for the selected categories 602, such as overall response time, overall read I/O rate, read data rate, and overall read cache hit percentage. Instance 600b of the performance metric selection GUI shows a drop down menu 608 from which the user selects a specific performance metric for the selected cache percentage performance metric type, where in FIG. 6b the selection is shown as Overall Write Cache Hit Percentage.
Upon receiving (at block 410) user selection of at least one selected performance metric of the determined performances metrics rendered in the performance metric GUI 600a, 600b, 600c, a time period and a reporting period, the storage performance manager 108 determines (at block 412) whether the performance metric database 110 includes performance metric values for the selected interval and time period for the selected storage systems. If there are not performance metric values for the selected interval and time period, then the storage performance manager 108 communicates (at block 414) with the selected storage systems 2001, 2002, 2003 . . . 200n not having performance metric values for the interval and sample period to obtain the performance metrics for the interval and sample period and store in the performance metric database 110. If (at block 412) the performance metric database 110 has the values for the interval and time period or after obtaining requested metrics (from block 414), the storage performance manager 8 determines (at block 416) from the performance metric database 110 performance metric values at the selected interval over the selected sample period for the at least one of the selected common performance metrics for the selected storage systems. The storage performance manager 108 generates (at block 418) a computer renderable visualization providing a visual comparison for each of the at least one selected performance metric of the determined performance metric values for the selected storage systems.
A computer renderable visualization may comprise a computer readable file having computer code to instruct a computer how to render the content therein, including performance metric values across storage systems 2001, 2002, 2003 . . . 200n and their components,
FIG. 7 illustrates an example of a computer renderable storage system performance chart 700 generated at block 418 in FIG. 4, where FIGS. 7A, 7B, 7C, and 7D provide expanded views of the panels in FIG. 7. FIG. 7 shows a plurality of sub-visualizations for the selected performance metrics that provides for each selected performance metric a chart having a graph of the performance metric values over the selected storage systems. FIG. 7 shows four sub-visualizations including an overall response time (ms/operation) visualization 7021 (FIG. 7A), an overall read I/O rate visualization (operations per second) 7022 (FIG. 7B), a read data rate 7023 (MB per second) (FIG. 7C), and an overall read cache hit percentage 7024 (FIG. 7D). Two of the visualizations 7021 and 7024 provide values for the selected common performance metrics for four of the selected storage systems and two others 7022 and 7023 provide visualizations for two of the storage systems.
FIG. 8 illustrates an example of a computer renderable storage system performance chart 800 table generated at block 418 in FIG. 4. FIG. 8 shows a plurality of sub-visualizations for the selected performance metrics that shows for each common performance metric a column of values for each of the selected storage systems. FIG. 8 shows four sub-visualizations including an overall response time (ms/operation) visualization 8021, an overall read I/O rate visualization (operations per second) 8022, a read data rate 8023 (MB per second), and an overall read cache hit percentage 8024. The metric values for each of three storage systems 8041, 8042, and 8043 are provided in each of the visualizations.
FIGS. 9a and 9b illustrate an embodiment of operations performed by the storage performance manager 108 to provide a series of graphical user interface (GUI) panels to enable a user to select options to generate a performance report that compares performance metrics across storage systems 2001, 2002, 2003 . . . 200n and components in storage systems, such as configured storage resources 204, computational resources 214, and storage devices 202. Upon initiating (at block 900) performance metric report generating, the storage performance manager 108 generates (at block 902) a component type selection GUI enabling selection of a selected component type from one of a plurality of component types in the storage systems, such as through drop down menu, selectable list or other GUI element to enable selection from one of a plurality of component types. The performance metric database 110 may maintain information on the possible component types in the storage systems 2001, 2002, 2003 . . . 200n. Upon receiving selection (at block 904) of a selected component type rendered in the component type selection GUI, the storage performance manager 108 generates (at block 906) a storage system selection GUI 1002 in FIG. 10 enabling selection from indication of a plurality of storage systems 2001, 2002, 2003 . . . 200n for which information 300 is maintained in the performance metric database 110. FIG. 10 illustrates an example of the storage system selection GUI 1000 having a drop down menu 1002 from which the user selects one of the storage systems 2001, 2002, 2003 . . . 200n, where the selected storage systems are shown as highlighted.
Upon receiving (at block 908) selection of selected storage systems from the storage system selection GUI 1000, the storage performance manager 108 determines (at block 910) from the performance metric databases 110 components of the selected component type in the selected storage systems. In one embodiment, the components may be determined by computer processing the performance metric information 300 for each of the selected storage systems 302 to determine particular components 304 of the selected component type. A component selection GUI enabling selection of selected components of the determined components is generated (at block 912). The components may be listed in a drop down list from which multiple may be selected or with other GUI selection techniques. FIG. 10 illustrates an example of the component selection GUI 1004 in which the user has selected components from the selected storage systems, which components are storage pools 208 in FIG. 10.
Upon receiving (at block 914) selection of multiple of the rendered components from one or more storage systems 2001, 2002, 2003 . . . 200n, the storage performance manager 108 determines (at block 916) from the performance metric database 110, performance metrics common to the selected components. These may be determined by determining from the performance metric information 300 for the selected components 302 the performance metrics 3061, 3062 . . . 306n in common among all the selected components 302.
Control proceeds to block 918 in FIG. 9b where the storage performance manager 108 generates a performance metric selection GUI enabling selection of the determined performance metrics common to the selected components, selection of a time interval at which the performance metric values are sampled, and selection of a reporting period over which the performance metrics are sampled at the time intervals.
FIG. 11 illustrates an example of the performance metric selection GUI 1100 showing different categories of selected performance metrics 1102 common to the selected components that may be selected. The user may select a category of common performance metrics 1102 using the drop down menus, where selection is made of the performance metric categories of Response Time, I/O Rate, Data Rate, Transfer Size along with the Interval and sample period. The performance metric selection GUI 1100 has the selected performance metrics 1104 selected from the selected categories 1102, such as overall response time, overall read I/O rate, total data rate, and overall transfer size. Further, the drop down menus 1104 in the GUI 1100 to select specific performance metrics for the selected categories are further shown in FIGS. 6a, 6b, 6c. 
Upon receiving (at block 920) user selection of at least one selected performance metric of the determined performances metrics rendered in the performance metric selection GUI 1100 (FIG. 11), a time period and a reporting period, the storage performance manager 108 determines (at block 922) whether the performance metric database 110 includes performance metric values for the selected interval and time period for the selected storage systems. If there are not performance metric values for the selected interval and time period, then the storage performance manager 108 communicates (at block 924) with the selected storage systems 2001, 2002, 2003, . . . , 200n not having performance metric values for the interval and sample period to obtain the performance metrics for the interval and sample period and store in the performance metric database 110. If (at block 922) the performance metric database 110 already has the values for the interval and time period or after obtaining requested metrics (from block 922), the storage performance manager 8 determines (at block 926) from the performance metric database 110 performance metric values at the selected interval over the selected sample period for the at least one of the selected performance metrics for the selected storage systems. The storage performance manager 108 generates (at block 928) a computer renderable visualization providing a visual comparison for each of the at least selected performance metric of the determined performance metric values for the selected storage systems.
FIG. 12 illustrates an example of a computer renderable storage system performance chart 1200 generated at block 928 in FIG. 9b, where FIGS. 12A, 12B, 12C, and 12D provide expanded views of the panels in FIG. 12. FIG. 12 shows a plurality of sub-visualizations for the selected performance metrics that shows for each performance metric a chart having a graph of the performance metric values over the selected storage systems. FIG. 12 shows four sub-visualizations including an overall response time (ms/operation) visualization 12021 (FIG. 12A), an overall read I/O rate visualization (operations per second) 12022 (FIG. 12B), a total read data rate 12023 (MB per second) (FIG. 12C), and an overall transfer size 12024 (FIG. 12D).
FIG. 13 illustrates an example of a computer renderable storage system performance chart table 1300 generated at block 928 in FIG. 9b. FIG. 13 shows a plurality of sub-visualizations for the selected performance metrics that shows for each performance metric a column of values for each of the selected storage systems. FIG. 13 shows four sub-visualizations including an overall response time (ms/operation) visualization 13021, an overall read I/O rate visualization (operations per second) 13022, a total data rate 13023 (MB per second), and an overall transfer size visualization 13024. The table 1300 further has groupings of storage systems 1304 in the second row of the table, and for each storage system, columns 1306 for the components for which the performance metric values are listed.

By way of example only, storage system 1413 can be provided for reading from and writing to a non-removable, non-volatile magnetic media (not shown and typically called a “hard drive”). Although not shown, a magnetic disk drive for reading from and writing to a removable, non-volatile magnetic disk (e.g., a “floppy disk”), and an optical disk drive for reading from or writing to a removable, non-volatile optical disk such as a CD-ROM, DVD-ROM or other optical media can be provided. In such instances, each can be connected to bus 1408 by one or more data media interfaces. As will be further depicted and described below, memory 1406 may include at least one program product having a set (e.g., at least one) of program modules that are configured to carry out the functions of embodiments of the invention.
Program/utility 1414, having a set (at least one) of program modules 1416, may be stored in memory 1406 by way of example, and not limitation, as well as an operating system, one or more application programs, other program modules, and program data.
