Using Adaptive Optimization

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.

NOTE: Adaptive Optimization is only supported by InForm OS versions 2.3.1 MU 1 and beyond.

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,
