1 Performance management

This chapter provides an overview on performance management of the XP7 Storage system, and describes the system requirements.

Overview of performance management

The XP7 Storage system includes a suite of performance management software products that allow you to monitor and tune storage system performance to improve and optimize storage utilization and performance.

• Performance Monitor: Enables you to collect and analyze detailed performance and usage statistics for the XP7 Storage as well as statistics about workloads on drives and traffic between the hosts and the storage system. You can view the data in lists and on graphs, and you can export the data for analysis in a spreadsheet and other applications.

• Performance Control: Enables you to control port activity to provide high-priority hosts with higher throughput and prevent production servers from experiencing degraded performance. Performance Control monitors the data being collected by Performance Monitor and applies upper-limit control and threshold control according to user-specified settings.

• Cache Residency: Enables you to improve host access to frequently accessed data by retaining the data in the storage system's cache memory to make it available at front-end access speeds.

You can perform performance management operations using Remote Web Console and RAID Manager for the XP7 Storage system. For details about the Remote Web Console, see the XP7

Remote Web Console User Guide. For details about RAID Manager, see the XP7 RAID Manager User Guide.

System requirements

• Performance management products. The performance management software products for the XP7 Storage system are required for performance management operations.

◦ Performance Monitor

◦ Performance Control

◦ Cache Residency

• License keys. The license keys for the performance management software products must be installed. For details about installing license keys, see the XP7 Remote Web Console User Guide.

• Java. Java is required for Performance Control and Cache Residency. For details about installing Java and configuring Remote Web Console, see the XP7 Remote Web Console User Guide.

• Remote Web Console secondary window. The Remote Web Console secondary window must be enabled before you use Performance Control or Cache Residency. Java and some settings of Remote Web Console are required for the Remote Web Console secondary window. For details, see the chapter on how to use the Remote Web Console secondary window in the XP7 Remote Web Console User Guide.

• Cache memory for Cache Residency. Use of Cache Residency might require additional cache memory in the XP7 Storage system. For details, see “Estimating cache size for Cache

Residency” (page 140).

8 Performance management

2 Performance Monitor operations

This chapter describes performance monitoring and provides instructions for conducting performance monitoring operations using Performance Monitor.

Overview of Performance Monitor

Performance Monitor enables you to monitor your XP7 Storage system and collect detailed usage and performance statistics. You can view the data in lists and on graphs to identify changes in usage rates and workloads, analyze trends in disk I/O, and detect peak I/O times. For example, if there is a decrease in performance, such as delayed host response times, you can use Performance Monitor to discover the reason for the decrease and determine the actions to take to improve performance.

Performance Monitor collects data about storage system resources such as drives, volumes, and microprocessors as well as statistics about front-end (host I/O) and back-end (drive I/O) workloads. You can perform both short-range monitoring and long-range monitoring. For long-range monitoring, data is collected constantly. For short-range monitoring, the data is collected when the Monitoring Switch is set to Enable, and you specify when and how often the data is collected. Using the Performance Monitor data, you can manage and fine-tune the performance of your storage system using the performance management software products for the system.

• “Data collected by Performance Monitor” (page 9)

• “Short-range monitoring” (page 9)

• “Long-range monitoring” (page 10)

• “Performance Monitor data graphs” (page 11)

• “Export Tool for Performance Monitor” (page 11)

Data collected by Performance Monitor

Performance Monitor allows you to collect the performance and usage statistics for the XP7 Storage system. All statistics are available for short-range monitoring. Most of the storage system usage statistics are available for long-range monitoring. For details about the performance and usage statistics, see “Monitoring data” (page 29).

Short-range monitoring

When you perform short-range monitoring of the storage system, you control when the statistics are collected (in real time or during a specified period of time) and how often the statistics are collected (from once per minute to once every 15 minutes). Short-range monitoring occurs in parallel with and does not affect long-range monitoring activities. All performance and usage statistics are available for short-range monitoring.

Overview of Performance Monitor 9

The sampling interval is the length of time between data collection events for short-range monitoring. The following number of CUs to be monitored determines the options for setting the sampling interval:

• Up to 64 CUs. If there are 64 or fewer CUs to be monitored, you can set the sampling interval from 1 minute to 15 minutes in increments of 1 minute. For example, when the sampling interval is set to 3 minutes, Performance Monitor collects statistics once every 3 minutes.

◦ Performance Monitor collects statistics for 1 day when data is collected at 1-minute

intervals.

◦ Performance Monitor collects statistics for up to 15 days when data is collected at

15-minute intervals.

• More than 64 CUs. If there are more than 64 CUs to be monitored, you can set the sampling interval to 5, 10, or 15 minutes.

◦ Performance Monitor collects statistics for one day when data is collected at 5-minute

intervals.

◦ Performance Monitor collects statistics for up to three days when data is collected at

15-minute intervals.

For short-range monitoring the SVP can store a maximum of 1,440 data collection events if there are 64 or fewer CUs to be monitored. Based on this number and the sampling interval, you can calculate the maximum storing period for the statistics as the sampling interval multiplied by 1,440. For example, if you set the sampling interval to 1 minute, the maximum storing period for the statistics is 1 day (24 hours):

1 minute x 1440 = 1440 minutes = 24 hours = 1 day

If you set the sampling interval to 15 minutes, the maximum storing period for the statistics is 15 days:

15 minutes x 1440 = 21600 minutes = 360 hours = 15 days

This maximum storing period is the maximum range of display in the Monitor Performance windows. When you specify one minute for the sampling interval as in the example above, Performance Monitor displays the statistics for a maximum of one day (24 hours) in the lists and graphs. When you specify 15 minutes for the sampling interval, Performance Monitor displays the statistics for a maximum of 15 days in the lists and graphs.

If there are more than 64 CUs to be monitored, SVP can store a maximum of 288 data collection events. Based on this number and the sampling interval, you can calculate the maximum storing period for the statistics as the sampling interval multiplied by 288. For example, if you set the sampling interval to 5 minutes, the maximum storing period for the statistics is 1 day (24 hours):

5 minutes x 288 = 1440 minutes = 24 hours = 1 day This maximum storing period is the maximum range of display in the Monitor Performance

windows. When you specify one minute for the sampling interval, as in the previous example, Performance Monitor displays the statistics for a maximum of 1 day (24 hours) in the lists and graphs. When you specify 15 minutes for the sampling interval, Performance Monitor displays the statistics for a maximum of three days in the lists and graphs.

Long-range monitoring

When you perform long-range monitoring of the storage system, you control when the statistics are collected in real time or during a specified period of time. The long-range monitoring statistics are collected at fixed 15-minute intervals (0, 15, 30, and 45 minutes of every hour) and stored for up to 6 months (186 days). Long-range monitoring occurs in parallel with and does not affect short-range monitoring activities.

10 Performance Monitor operations

You can collect the following statistics in long-range monitoring:

• Usage rates of MPs

• Usage rates of DRRs

• Write-pending statistics

• Access path usage statistics

• Data drive usage statistics

• Data drive access rates

Performance Monitor data graphs

You can view both the short-range and long-range statistics on data graphs. All statistics can be viewed in short range (for the storing period corresponding to the sampling interval setting). Usage statistics about storage system resources, which are monitored in both ranges, can be viewed in both short range and long range. When viewing usage statistics about resources, you can specify the range to view and which part of the storing period to display on lists and graphics. A few storage system usage statistics are not available for long-range monitoring.

For details about the Performance Monitor data graphs, see “About the data graphs” (page 25).

Export Tool for Performance Monitor

The Export Tool software that comes with Performance Monitor allows you to export the monitoring data in a .csv file for analysis, for example, using spreadsheet software or database software. You can also use Export Tool to save and accumulate data over extended periods of time for long-term analysis and future reference.

For details about Export Tool, see “Exporting Performance Monitor data” (page 49).

Cautions and restrictions for Performance Monitor

• “Cautions and restrictions for monitoring” (page 11)

• “Cautions and restrictions for usage statistics” (page 12)

Cautions and restrictions for monitoring

• Performance monitoring switch

When the performance monitoring switch is set to disabled, short-range monitoring data is not collected.

• Changing the SVP time setting

If the SVP time setting is changed while the monitoring switch is enabled, the following monitoring errors can occur:

◦ Invalid monitoring data appears.

◦ No monitoring data is collected.

If you have changed the SVP time setting, disable the monitoring switch, and then re-enable the monitoring switch. Next, obtain the monitoring data. For details about the monitoring switch, see “Starting monitoring” (page 14).

• WWN monitoring

You must configure some settings before the traffic between host bus adapters and storage system ports can be monitored. For details, see “Adding new WWNs to monitor” (page 16),

“Adding WWNs to ports” (page 17), and “Connecting WWNs to ports” (page 19).

Cautions and restrictions for Performance Monitor 11

• Parity group monitoring

To correctly display the performance statistics of a parity group, all volumes belonging to the parity group must be specified as monitoring targets.

• Storage system maintenance

If the storage system is undergoing the following maintenance operations during monitoring, the monitoring data might not be valid:

◦ Adding, replacing, or removing cache memory

◦ Adding, replacing, or removing data drives

◦ Changing the storage system configuration

◦ Replacing the microprogram

◦ Formatting or quick-formatting logical devices

◦ Adding, replacing, or removing MP blades

• Storage system power-off

If the storage system is powered off during monitoring, monitoring stops until the storage system is powered on again. Monitoring resumes when the storage system is powered on again. However, Performance Monitor cannot display information about the period while the storage system is powered off. Therefore, the monitoring data immediately after powering on again might contain extremely large values.

• Microprogram replacement

After the microprogram is replaced, monitoring data is not stored until the service engineer releases the SVP from Modify mode. Therefore, inaccurate data might be temporarily displayed.

Cautions and restrictions for usage statistics

• Retention of short-range and long-range usage statistics

Usage statistics for the last six months (186 days) are displayed in long-range monitoring, and usage statistics for up to the last 15 days are displayed in short-range monitoring. Usage statistics outside of these ranges are deleted from the SVP. In short range monitoring, results are retained for the last 1 to 15 days depending on the specified sampling interval. If the retention period has passed since a monitoring result was obtained, the previous result has been deleted from the SVP and cannot be displayed.

• Statistics for periods of high I/O workload

For short-range monitoring, if the host I/O workload is high, the storage system gives higher priority to I/O processing than to monitoring. If this occurs, some monitoring data might be missing. If monitoring data is missing frequently, use the Edit Monitoring Switch window to lengthen the sampling interval. For details, see “Starting monitoring” (page 14).

• Volumes and CU ranges

The volumes to be monitored by Performance Monitor are specified by control unit (CU). If the range of used CUs does not match the range of CUs monitored by Performance Monitor, usage statistics might not be collected for some volumes.

• Reverse resync operations

When you run the RAID Manager horctakeover command, the pairresync-swaps command for a Cnt Ac-J pair, or the BCM YKRESYNC REVERSE command for a Cnt Ac-J MF pair,

12 Performance Monitor operations

the primary and secondary volumes are swapped. You can collect the before-swapped information immediately after you run any of the commands. Invalid monitoring data will be generated for a short time but will be corrected automatically when the monitoring data gets updated. The invalid data will temporarily be generated when the volume used for a secondary volume is used as a primary volume after a Cnt Ac-J pair or Cnt Ac-J MF pair is deleted.

• Display of monitoring data immediately after monitoring starts or immediately after the sampling interval is changed

Monitoring data cannot be displayed within the first two sampling intervals after the monitoring starts or the sampling interval is changed because no monitoring data has accumulated. For instance, if the sampling interval is set or changed to 15 minutes, monitoring data is not accumulated for up to 29 minutes after this setting is made.

• Display of monitoring data during high SVP workload

If the SVP is overloaded, the system might require more time than the sampling interval allows to update the display of monitoring data. If this occurs, a portion of monitoring data is not displayed. For example, suppose that the sampling interval is 1 minute, and the display in the Performance Management window is updated at 9:00 and the next update occurs at 9:02. In this case, the window (including the graph) does not display the monitoring result for the period of 9:00 to 9:01. This situation can occur when the following maintenance operations are performed on the storage system or on the Remote Web Console PC:

◦ Adding, replacing, or removing cache memory.

◦ Adding, replacing, or removing data drives.

◦ Changing the storage system configuration.

◦ Replacing the microprogram.

• Pool-VOLs

3 Performance Monitor data

This chapter provides detailed descriptions of the monitoring data collected and displayed by Performance Monitor.

Monitoring data

The following table lists the objects that can be monitored and specifies the data that is collected for each monitoring object. You can specify the objects that are displayed in the graphs in the Performance Objects in the Monitor Performance window. When the resource group feature is installed, you can specify the objects to be displayed in the graphs only when the resources that are shown in the necessary resources in the following table are allocated.

The monitoring data for each sampling interval is the average value of the data over the data sampling interval. The sampling interval is 1 to 15 minutes for Short Range and 15 minutes for Long Range. The monitoring data shows the information by each resource ID even when the volume is in a virtual storage machine (not by virtual ID). For instructions on viewing the monitoring data, see “Using the Performance Monitor data graphs” (page 24).
