HP 3PAR System Tuner Software spreads volumes evenly and widely across all available resources so that HP 3PAR Storage can deliver balanced performance. However, as the storage system scales and new applications come online, new access patterns may emerge that result in sub-optimal performance levels.

HP 3PAR System Tuner Software autonomically and non-disruptively detects potential bottlenecks and hotspots then rebalances volumes to maintain peak performance without impacting service levels or changing pre-existing service level characteristics such as RAID level.        

Features

Autonomically Maintains Peak Performance Over Time

HP 3PAR System Tuner Software automatically detects and eliminates bottlenecks and hotspots without disrupting applications or impacting service levels.
Detects unforeseen storage access patterns and addresses any issues to ensure consistently high performance.
Retains all pre-existing service level parameters such a RAID levels and disk type.
Relocation operations run as a background process that is non-disruptive to users and applications.

Customizable Solution Delivers Administrative Simplicity, Flexibility, and Control

HP 3PAR System Tuner Software targets underperforming storage at the sub-volume level by identifying fine-grained capacity units that fall below a specific user-definable threshold.
Configurable thresholds can be adjusted according to multiple criteria related to service times.
Can be set to examine all capacity in the array or a subset of the system, such as a specified group of physical disks.
