HPE 3PAR Adaptive Optimization - A quick summary for beginners

[sbhat09]

Hello,

HPE 3PAR Adaptive Optimization (AO) is a great feature that facilitates hybrid storage using multiple disk tiers. By enabling AO, you can effectively utilize expensive SSD drives at their best value.

To summarize the significance of AO, for example, if you have created a volume in the SSD tier, the chances are high that only 10-20% of the data in that volume is frequently accessed by the users and would really require SSD performance. The rest of the data may not justify their occupancy on an expensive SSD tier. While some data on FC or NL tier may be frequently accessed by the hosts/users and experience performance lag.

3PAR Adaptive Optimization helps you to meet the requirements of the volumes on all the tiers. AO combines 2 or 3 CPGs (different tiers) where it moves the hot data of all the volumes on member CPGs to SSD tier, rest of the data to FC, NL tier based on the access rate (frequency of read-write). AO uses it's own intelligent algorithm to move the data between the tiers based on the free space, qualified data, and the mode (performance, balance and cost) you have selected. You can create multiple AO configurations on the same system, opt certain CPGs in a tier and exclude the CPGs that you don't want to be part of the AO configuration.

AO analyses the system reporter data during business hours (usually daytime) and moves data between the tiers during off-business hours (usually night time) on daily basis. You can customize your business hours, non-business hours, days in a week to run AO, etc in AO schedule.
You can directly configure AO, login to SSMC -> Main menu -> Storage Optimization -> Adaptive Optimization -> Create new.
