This chapter provides information about the optionally licensed Adaptive Optimization
feature that works in conjunction with System Reporter to optimize storage utilization across
multiple tiers.
9.1 Overview
Adaptive Optimization analyzes sub-volume, region level disk access rates for a given array
over a scheduled period of time and then performs a data migration of regions between tiers
according to a cost versus performance preference. Disk utilization is optimized by having
frequently accessed data moved to the higher performance tier (e.g., RAID 1 using Solid State
Disks or SSDs) while infrequently accessed data is moved to the lower cost tier (e.g., RAID 6 on
Nearline disks). By using Adaptive Optimization, you can achieve a much higher degree of
control over disk usage by reserving your faster and more expensive storage resources for the
data that is frequently accessed and relegating your slower and less expensive drives to storing
data that is only occasionally accessed.
Multiple Adaptive Optimization configurations can be defined for an InServ array where each
corresponds to a related set of hosts or applications that require optimization. You can assign
either two or three storage tiers (defined through tiers numbered 0, 1 and 2) for data
migration in a given configuration where tier 0 is the fastest, tier 1 is the intermediate speed,
NOTE: Adaptive Optimization is only supported by InForm OS versions 2.3.1 MU 1
and beyond.
