What should the customer implement?
A. quad controllers
B. Adaptive Optimization
C. 120 SSDs
D. Dynamic Optimization
Correct Answer: B
Explanation/Reference:
Explanation:
The HP 3PAR Adaptive Optimization (AO) software takes optimization a step further into sub-LUN tiering. AO migrates sub-LUN data across CPGs based on user-defined policies. Two or three CPG tiers can be specified per policy; all volumes inside a CPG are subject of an AO policy. AO policies usually operate on an FC and NL tier or on an SSD, FC, and NL tier. This tool can improve system response and reduce disk acquisition cost by storing frequently accessed data in the faster tier while moving infrequently accessed data to the slower and cheaper slower tier.
Incorrect:
Not D: Related to online migration:
P 3PAR’s Dynamic Optimization (DO) software offers the functionality of EVA’s Dynamic LUN Migration: volumes are migrated online to another CPG with a different RAID level, set size, drive media type , etc.
