Page 9: Performance Monitor Operations
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.
Page 10: Long-Range Monitoring
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.
Page 11: Performance Monitor Data Graphs
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).

Page 69 Operand Description file name will be PhyExG_dat.ZIP. For details on the statistics exported by this operand, Table 5 (page 85). When you specify variable exg-id, you can narrow the range of external volume groups whose monitoring data are to be exported. exg-id is an ID of an external volume group. The colon (:) indicates a range.
Page 70 Operand Description Use this operand when you want to export statistics about parity groups, external volume [ [ p a r i t y - g r o u p - i d | e x g - i d | M i g r a t i o n - V o l u m e - g r o u p - i d ] : groups, or migration volume groups which are displayed in the Monitor Performance window.
Page 71 Operand Description Ensure that the LDKC-CU-id value on the left of the colon is smaller than the LDKC-CU-id value on the right of the colon. For example, you can specify LDEVEachOfCU 000:105, but you cannot specify LDEVEachOfCU 105:000. If internal is specified, you can export statistics about volumes in the parity group. If virtual is specified, you can export statistics about volumes in the external volume or V-VOL.

Operand Description URLDEV Use this operand when you want to export statistics about remote copy operations which of [ [ L D K C - C U - i d ] : [ L D K C - C U - i d ] ] [ … ] Cnt Ac-J and Cnt Ac-J MF.
Page 75 All the monitoring items are stored in short range. Therefore, you can use the shortrange subcommand whichever operand you specify to the group subcommand. If you run Export Tool without specifying the shortrange subcommand, the data stored in the whole monitoring term will be exported.
Page 76: Longrange
Operand Description be smaller than the original time. If this change occurs to the time on the right of the colon, the time will be larger than the original time. The following are the examples: If the time on the left is 10:15, the time on the right is 20:30, and the sampling interval is 10 minutes: The time on the left will be changed to 10:10 because the last two digits of the time are not a multiple of 10 minutes.
Page 77 The longrange subcommand is valid for monitoring data in long range. The monitoring data in long range is the contents displayed on the Physical tab of the Performance Management window with selecting longrange as the storing period. The monitoring items whose data can be stored in long range are limited. The following table shows the monitoring items to which the longrange subcommand can be applied, and also shows the operands to export those monitoring items.
Page 78: Outpath
Operand Description Adds time to the starting time for collecting monitoring data, if yyyyMMddhhmm is omitted. Subtracts time (ddhhmm) from yyyyMMddhhmm if yyyyMMddhhmm is specified. For example, -ddhhmm 201301120000-010130 indicates Jan. 10, 2013. 22:30. Subtracts time from the ending time for collecting monitoring data, if yyyyMMddhhmm is omitted.

Page 105: Performance Control Operations
5 Performance Control operations This chapter describes and provides instructions for managing host I/O activity using Performance Control. Overview of Performance Control Performance Control allows you to set upper limits of the number of accesses from the server to storage system as well as the amount of data transfer. The upper limits are automatically disabled when the traffic between the server and storage system drops to user-defined levels.
Page 106: Threshold Control
Related topics “Overview of Performance Control” (page 105) Threshold control While upper-limit control can help production servers to perform at higher levels during periods of heavy use, it may not be desirable when production servers are not busy. For example, if the I/O activity on production servers is high between 09:00 and 15:00 hours and decreases significantly after 15:00, upper-limit control for development servers may not be required after 15:00.
Page 107: Use Cases For Performance Control
Related topics “Overview of Performance Control” (page 105) Use cases for Performance Control This section describes the use cases for implementing Performance Control on the XP7 Storage system: “Use case for one-to-one connections” (page 107) “Use case for many-to-many connections” (page 109)
Page 108 Figure 7 Network A: 1-to-1 connections between HBAs and ports In Network A, ports 1A and 1C are connected to high-priority production servers. Port 2A is connected to a low-priority development server. Therefore, high priority (Prio.) is set to ports 1A and 1C, and low priority (Non-Prio.) is set to port 2A.
Page 109: Use Case For Many-To-Many Connections
After upper limit values have been applied, the traffic at the ports is measured to check the result of the upper limits and see whether host performance has improved to a desirable level, in this case 400 IO/s for ports 1A and 1C. If production server performance is not improved to a desirable level, you can adjust the upper limit to a smaller value until the I/O rate for the high priority servers reaches the desirable level.
Page 110 Before using Performance Control, you must find the WWN (Worldwide Name) of each host bus adapter in host servers. WWNs are 16-digit hexadecimal numbers used to identify host bus adapters. For details on how to find WWNs, see the XP7 Provisioning for Open Systems User Guide.
Page 111 The priority for the host bus adapters is set using the WWN tab of the Performance Control main window. In Network B, the production server is high priority (Prio.), and the development server is low priority (Non-Prio.). To give priority to the three host bus adapters, take the following steps: On the WWN tab of the Performance Control main window, select one of the four ports that the HBAs are connected to (that is, ports 1A, 1C, 2A, and 2C).
Page 112 Figure 11 Traffic at ports To maintain a higher I/O rate (400 IO/s) for the prioritized WWN, you can set upper limits on the I/O rate for the non-prioritized WWNs to minimize their effect on the performance of the high-priority production server.

Page 138: Cache Residency Operations
6 Cache Residency operations This chapter provides instructions for managing data in cache using Cache Residency. Overview of Cache Residency Cache Residency enables you to retain frequently accessed data in the storage system's cache memory so that it is immediately available to hosts. Using Cache Residency you can increase the data access speed for specific data by enabling read and write I/Os to be performed at the higher front-end access speeds.
Page 139: Prestaging Data In Cache
Bind mode provides the following advantages over priority mode: The accessibility of read data is the same as Cache Residency priority mode. Write operations do not have to wait for available cache segments. There is no back-end contention caused by destaging data. The required total cache capacity for bind mode is: standard cache + Cache Residency cache Cache Residency bind data that has write attributes is normally not destaged.
