1 Overview of Performance Monitor Performance Monitor provides usage statistics about physical hard disk drives, volumes, processors, or other resources in your storage system. Performance Monitor also provides statistics about workloads on disk drives and traffic between hosts and the storage system. The Auto LUN window displays a line graph that indicates changes in the usage rates, workloads, or traffic. You can view information in the window and analyze trends in disk I/Os and detect peak I/O time.
Overview of Performance Monitor
Figure 1 Performance Management Process Flow Diagram . HP StorageWorks XP Auto LUN Software lets you balance workload among hard disk drives, volumes (LUs) and processors to remove bottlenecks from your system. If Performance Monitor indicates that a lot of I/Os are made to some hard disk drives, you can use XP Auto LUN to distribute workloads to other disk drives. For details, see the HP StorageWorks XP24000/XP20000 Auto LUN Software User Guide.
Overview of Performance Monitor
2 About Performance Monitor This chapter gives an overview of performance management operations. • • • • Components, page 15 Overview of Performance Monitor, page 15 Overview of Export Tool, page 24 Interoperability with Other Products, page 25 Components To use Performance Monitor, you need: • The storage system • The Performance Monitor program products (Performance Monitor is required.
Software, and Hitachi Universal Replicator™ for Mainframe. The displayed contents are the same as those displayed in the Usage Monitor windows of each remote copy function. The Export Tool enables you to save information on the Auto LUN window into files, so you can use spreadsheet or database software to analyze the monitoring results. For detailed information about the Export Tool, see “Overview of Export Tool” on page 24 and Chapter 6 on page 99.
A RAID-5 parity group consists of four or eight HDDs. One of these HDDs is used as a parity disk. • RAID-6 parity group A RAID-6 parity group consists of eight HDDs. Two of these HDDs are used as a parity disk. If the monitor data shows overall high parity group usage, you should consider installing additional HDDs and using XP Auto LUN to migrate the high-usage volumes to the new parity groups.
External Volume Usage Statistics An external volume is a volume existing in an external storage system that is mapped to a volume in the storage system using XP External Storage. Performance Monitor can monitor and display the usage conditions for external volumes. The information that can be monitored for an external volume differs from that of a typical volume.
2. Check the usage rate of each parity group to find parity groups whose usage rate is lower than the parity groups that you want to migrate. It is recommended you migrate volumes from higherusage parity groups to lower-usage parity groups.
Cluster 1 Disk Adapter DKA-1KL Disk Processor Migrating Volumes in an XP24000 Disk Array DKP74-1KL Migrate volumes from parity groups with the following IDs to another parity group: DKP75-1KL DKP76-1KL 10-X DKP77-1KL 18-X DKPC0-2MU 2 DKA-2MU DKPC1-2MU DKPC2-2MU DKPC3-2MU DKPD0-2NU 2 DKA-2NU DKPD1-2NU DKPD2-2NU DKPD3-2NU DKPC4-2ML 2 DKA-2ML DKPC5-2ML DKA-2NL DKA-2XU DKA-2WU 20 DKA-2XL Migrate volumes from parity groups with the following IDs to another parity group: 2-X 4-X 12-X Mig
Cluster 2 Disk Adapter DKA-2WL Disk Processor Migrating Volumes in an XP24000 Disk Array DKPF4-2WL Migrate volumes from parity groups with the following IDs to another parity group: DKPF5-2WL DKPF6-2WL 10-X DKPF7-2WL 18-X NOTE: The letter X is a placeholder for numerical values. For example, parity group 1-X indicates parity groups such as 1-1 and 1-2.
Access Path Usage Statistics 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 cache switch (CSW) to the cache memory.
The I/O rate indicates how many I/Os are made to the hard disk drive in one second. If the I/O rate is high, the hosts might consume a lot of time for accessing disks and the response time might be long. • Transfer rate The transfer rate indicates the size of data transferred to the hard disk drive in one second. If the transfer rate is high, the hosts might consume a lot of time for accessing disks and the response time might be long.
8 hours to 15 days) and that changes depending on the collecting interval specified by the user. For details on the storing period of statistics, see “Understanding Statistical Storage Ranges” on page 16. The traffic statistics reported for an LU is aggregated across all LU paths defined for an LU. • I/O rate is the sum of I/Os across all LU paths defined for an LU. • Transfer rate is the total transfer rate across all LU paths defined for an LU.
Figure 3 An Example of a Text File . NOTE: • When you run the Export Tool, text files are usually compressed in a ZIP-format archive file. To open a text file, you must use decompress the ZIP file to extract the text files. • Text files are in CSV (comma-separated value) format, in which values are delimited by commas. Many spreadsheet applications can be used to open CSV files. • Do not run multiple instances of the Export Tool simultaneously.

Invalid Values of Monitoring Data Probable Causes Cause — The value "-4" indicates that Performance Monitor failed to obtain monitoring data. The monitoring data in the CSV file includes "-4". Reasons: • If the monitoring period for data with the export tool, does not match the collecting period, the export tool cannot collect the monitoring data. • If data of SVP is updated while the monitoring data is being collected, data collected near the start time is - 4.
