Performance Profiles Overview
Data Collection of array performance data is supported for certain vendor storage arrays. See the APTARE StorageConsole Certified Configurations Guide for a complete list of supported arrays. See also, Capacity Manager Array Performance Metrics.
Performance profiles reflect key performance metrics for groups of LUNs. These profiles are used to assign performance states to LUNs and hosts, as shown in several APTARE StorageConsole array performance reports. APTARE StorageConsole maintains aggregated performance profiles for each collection of RAID groups and thin pools that share common physical characteristics. These performance profiles categorize a host’s performance state, based on LUN performance: Slow, Normal, or Fast. All LUNs are mapped to either a RAID group or thin pool thereby enabling array performance reports to list the associated drives, drive types, and drive speed. See the following reports: Array Performance by RAID Group and Array Performance by LUN.
Performance profiles are derived from previously captured array raw performance statistics. APTARE StorageConsole’s internal procedures examine captured performance metrics for the specified interval and populate profiles with actual ranges of performance and throughput metrics for slow, normal, and fast performance states.
Performance profiles should be based on a typical peak array performance interval. By default, the updating of performance profiles occurs daily and uses an interval of 10:00 a.m. to 11:00 a.m. You should change the default interval to correspond to the peak array performance interval for your environment. When the Data Collector policy is configured, a recurring frequency is selected to set the length of the profile interval. Baseline profiling determines the range of metrics for I/Os, response time, and cache hits. See Determining Performance States and Populating Performance States.
An on-going scheduled daily task profiles collected data. Since certain times of day are more prone to performance issues, the performance profile schedule can be modified for your environment. For Performance Profile Schedule Customization, see Customize the Array Performance Profile Schedule in the System Administrator’s Guide.
Both internal and community profiling can be enabled.
Internal profiling compares periodic collection cycles within just your environment. Essentially, a library of metrics is maintained for comparisons.
Community profiling lets contributors securely import/export performance profiles over https, enabling comparisons with a broader community of similar arrays and environments. See Community Performance Profiling and Aggregated Profiles.
