Adapting Storage to User Demands

2-8 CLI Storage-Management Guide

An auto-migrate rule migrates files off of the over-burdened filers and onto the filers

with more available free space. In addition, the ARX ensures that no filer is

over-filled; all filers in the share farm maintain the minimum free space until/unless

they all fill up to this level.

Configuration Instructions

An auto-migrate rule is one of the share-farm rules described in Chapter 12, Policy for

Balancing Capacity. See “Auto Migrating Existing Files” on page 12-18.

Migration for Class of Storage: File-Placement Policy

Another application for namespace policy is adaptive migration of files onto selected

back-end storage. This migration is configured as a file-placement policy. To

configure file-placement policy, you can

1. group files into filesets based on criteria like names (such as *.xml or *.mpg),

location (/usr/local), and/or last-modified times,

2. differentiate your back-end filers by classifying them into different share farms

(optional), and

3. configure a file-placement policy to place a fileset onto a given share or share

farm.

The policy engine periodically re-examines its back-end files to re-group them into

filesets, then it moves them to the configured back-end share or share farm.
