1 Performance improvement of storage system Unless otherwise specified, the term P9000 in this guide refers to the following disk array: • P9500 Disk Array The GUI illustrations in this guide were created using a Windows computer with the Internet Explorer browser. Actual windows may differ depending on the operating system and browser used. GUI contents also vary with licensed program products, storage system models, and firmware versions.
2 About monitoring performance This chapter provides an overview of Performance Monitor and Cache Residency. Monitoring resource availability Performance Monitor tracks your storage system so that you can obtain statistics about the following: • Resources in your storage system • Workloads on disk and ports If your system encounters some problem (for example, if server hosts suffer delayed response times), Performance Monitor can help you detect the cause of the problem.
NOTE: Notes of Cache Residency show as follows: • If you have accessed the Cache Residency area for input and output before the prestaging operation is performed from the SVP or Remote Web Console, the host may not be able to find data in the cache at the first I/O access after Cache Residency is configured. • In order to prevent the response time of host I/O being slow, the prestaging operation may be interrupted when the cache load is heavy.
is duplexed in the Cache Residency area, which consumes a significant amount of the Cache Residency cache. In Bind Mode, the total capacity of cache required is: standard cache + Cache Residency cache The following table specifies the cache requirements for bind mode operations. For further information on calculating procedures for required cache size for using Cache Residency if the bind mode is set, see “Estimating cache size ” (page 38).
Changing the mode without cache extension requires reconfiguring of Cache Residency (i.e., release the data from cache, and then place the data back in cache with the desired mode).
3 Interoperability of Performance Monitor and other products This chapter describes the interoperability of Performance Monitor and other products. Maintenance If the storage system is undergoing following maintenance operations during monitoring, the monitoring data might contain extremely large values. • Adding on, replacing, or removing cache memories. • Adding on, replacing, or removing disk drives. • Changing the system configuration. • Replacing the micro program.
◦ Changing the system configuration. ◦ Replacing the micro program. Viewing the WWN monitoring data To start monitoring traffic between host bus adapters and storage system ports, you must make settings before starting monitoring.

7 Setting statistical storage ranges This chapter describes statistical storage ranges. About statistical storage ranges Performance Monitor collects and stores statistics for two time periods (ranges): short range and long range. The difference between the two ranges and the statistics they target are as follows: • Short range If the number of CUs to be monitored is 64 or less, statistics are collected at a user-specified interval between 1 and 15 minutes, and stored between 1 and 15 days.
5. Select Set Range or Use Real Time in the Time Range as the periods (ranges) for displaying statistics. If Long-Range is selected, you can specify only Set Range. If Short-Range is selected, you can select Set Range or Use Real Time. Performance Monitor saves the statistics obtained up to 1440 times in SVP. Therefore, you can estimate the storing period of statistics with "gathering interval multiplied by 1440".

Storing period Short-Range or Long-Range can be specified. Selecting of monitoring objects Select monitoring objects in Performance Objects: field. The combination of items is shown as follows.
Access paths usage statistics Function An access path is a path through which data and commands are transferred within a storage system. In a storage system, channel adapters control data transfer between hosts and the cache memory. Disk adapters control data transfer between the cache memory and hard disk drives. Data transfer does not occur between channel adapters and disk adapters. Data is transferred via the ESW (PCI Express Switch adapter) to the cache memory.
Throughput of storage system Function Total throughput is the sum of I/Os to LDEVs, parity groups or LUNs The read throughput is I/Os to the disk per second when the file read processing is performed. The write throughput is I/Os to the disk per second when the file write processing is performed. Throughputs in the following modes can be displayed.

If you want to delete the item, select the item and then click Deselect. Click OK. The graph is added.
10 Estimating cache size This chapter describes how to estimate the cache size required for using Cache Residency. About cache size The required cache size for using Cache Residency differs according to operation modes or RAID levels. For example, if the bind mode is set, RAID1 storage systems require twice the size of cache for the user data to use Cache Residency. However, RAID5 or RAID6 storage systems require three times the size of cache.
Calculating cache size for open systems 1. Calculate the converted values of the starting address and the ending address. For all specified LDEVs: 1. For OPEN-V: Number of LBAs = LDEV size (KB)×2 Convert the LDEV size to the number of LBAs. Number of slots = ceil (Number of LBA ÷ 512) Round up the value that is calculated from the formula enclosed by ceil(). Converted value of starting address = 0 Converted value of ending address = (Number of slots × 512) - 1 2.
1. For OPEN-V: Number of addresses = Converted value of ending address - Converted value of starting address + 1 Calculate the number of LBAs that are used by the user data. 2. For emulation types other than OPEN-V: Number of LBAs = Converted value of ending address - Converted value of starting address + 1 Calculate the number of LBAs that are used by the user data. Number of slots = Number of LBAs ÷96 Convert the number of LBAs to the number of slots.
Calculating cache size for mainframe systems 1. Calculate the converted values of the starting address and the ending address. a. For all specified LDEVs: Setting value of ending address (CC) = floor (((LDEV size × 15) - 1) ÷ 15) Round down the value that is calculated from the formula enclosed by floor(). "Setting value of ending address (CC)" is the value which is input on the Cache Residency window.
• For mainframe volumes, each Cache Residency cache extent must be defined on contiguous tracks, with a minimum size of one cache slot (or track) and a maximum size of one LVI. This is equivalent to 66 KB. • For OPEN-V volumes, Cache Residency cache extents must be defined in logical blocks using logical block addresses (LBAs), with a minimum size of 512 LBAs (equivalent to 264 KB). However, in most cases you will assign an entire open-system volume for Cache Residency.
11 Managing resident cache This chapter provides information and instructions for using Cache Residency software to manage resident cache. Cache Residency rules, restrictions, and guidelines Rules • Cache Residency must be enabled on Remote Web Console. • Administrator or Cache Residency write access to the Remote Web Console software is required to perform Cache Residency operations.
The following operations automatically reset Cache Residency cache: ◦ When LDEVs that is partly or wholly assigned to Cache Residency is deleted. ◦ When the parity group containing LDEVs that are assigned to Cache Residency is deleted. Figure 6 Example of LBA Value Setting When Using LUSE Restrictions • The Cache Residency bind mode is not available to external volumes whose Cache mode is set to Disable (which is the mode that disables the use of the cache when there is an I/O request from the host).
Launching Cache Residency 1. 2. 3. Log on to the primary SVP. When you successfully log on to the primary SVP, the Remote Web Console main window opens. On the menu bar of the Remote Web Console main window, click Actions→Other function→Cache Residency. In the Cache Residency window, click modify mode. . Change the mode between the view mode and Viewing Cache Residency information The Cache Residency information can be viewed in the following fields in the Cache Residency window.
NOTE: For OPEN-V LUs, Cache Residency identifies a logical area in units of 512 blocks. If you enter 0 or 1 as the starting LBA and a value less than 511 as the ending LBA, Cache Residency automatically changes the ending block address to 511. 4. In the Cache Residency window, select options to apply to all selected LDEVs: 1. In the Cache Residency Manager Mode box, select the desired mode (Bind or Priority). 2. Select the desired Prestaging Mode setting (Yes or No).
8. 9. To start the operation(s), click Apply. If Prestaging was selected, respond to the Yes/No confirmation. To continue with prestaging, click Yes.

A Export Tool This chapter explains how to use the Export Tool to export into files the monitoring data collected on your storage system. About the Export Tool Use the Export Tool to export the monitoring data (statistics) shown in the Monitor Performance window to text files. You can also use the Export Tool to export monitoring data on remote copy operations performed by Continuous Access Synchronous, Continuous Access Synchronous Z, Continuous Access Journal, and Continuous Access Journal Z.
4. Change the directory to the created directory. #cd /monitor 5. Copy the CD-ROM to the created directory. For HP-UX system: # cp/ /program/monitor/HP_UX/export.tar For Solaris: # cp/ /program/monitor/solaris/export.tar For Linux: # cp/ /program/monitor/HP_UX/export.tar 6. Execute the program file. # tar xvf export.
The JRE version required for running the Export Tool is the same as the JRE version required for running Remote Web Console. ◦ A user ID for exclusive use of the Export Tool To use the Export Tool, you must create a user ID exclusively for the Export Tool. HP recommends that you assign only the Storage Administrator (Performance Management) role to the user ID for the Export Tool to manage the storage system.
4. Decompress export.tar on your computer. The Export Tool is installed. Also, a new directory named export is created. NOTE: Consider the following: • The export directory contains several files including runWin.bat. We recommend that you delete runWin.bat because this file is no longer needed. • The Export Tool program is a Java class file and is located in the export/lib directory. Using the Export Tool To be able to export monitoring data, you must prepare a command file and a batch file.
• show The show subcommand checks SVP to find the period of monitoring data stored in SVP and the data collection interval (called gathering interval in Performance Monitor), and then outputs them to the standard output (for example, the command prompt) and the log file. Performance Monitor collects statistics by the two types of storing periods: in short range and in long range. The show subcommand displays the storing periods and the gathering intervals for these two types of monitoring data.
by these operands are the monitoring data displayed in the Physical tab of the Performance Management window with selecting longrange.) Specify a term within "Long Range From XXX To XXX" which is output by the show subcommand.
