Why each option
HP 3PAR Adaptive Optimization continuously monitors I/O at the sub-LUN level and automatically relocates data between storage tiers to maintain the performance each application requires.
Enhanced Priority Optimization applies QoS-style IOPS and bandwidth throttling to control workload priority between competing applications but does not move data between tiers to sustain minimum performance levels.
Deploying SSDs is a static hardware decision that improves potential throughput but does not dynamically adapt data placement based on changing application I/O demand.
Adaptive Optimization analyzes I/O patterns across 256 MB sub-LUN regions and migrates frequently accessed data to higher-performance tiers such as SSD, ensuring applications consistently receive the minimum IOPS and low latency they require without manual intervention or scheduled jobs.
Dynamic Optimization enables non-disruptive migration of volumes between RAID types and CPGs for resiliency or capacity changes and is not designed to guarantee minimum performance for specific applications.
