38 Configuring FSE
• Define your migration and release policies regarding the characteristics of files on each individual file
system, such as how much are the files in use, are these “working” files or files that simply need to be
retained safely, how often do you want these files to be migrated, and so on.
• Consider the effect of your policies on your FSE implementation and tune it accordingly.
Configuration basics
All FSE resources, namely FSE library, FSE drive, FSE media pool, FSE medium, and FSE medium volume,
must be configured before you can start using FSE. You configure FSE resources using configuration plain
text files. See also section ”Using the FSE Management Console for configuring resources and policies” on
page 41 for a graphical interface to most of the tasks.
Configuration files
The plain text file format, used for configuration files, has the following advantages:
• Simple editing and modification
To edit and modify your configuration files, you can use any tool that can save files as plain text.
• Similar syntax for each component
You configure your resources using corresponding syntax, considering the requirements of a particular
resource.
• Parsing
You can collect data from existing, already applied configuration files using parsing utilities and scripts.
• Use of comments
You can add your own comments to configuration files. Comments are introduced with a hash
character (#) in order to be marked and preserved.
FSE configuration file elements
Each configuration file consists of particular elements, which can be grouped as follows:
The following example shows the elements as they are represented in the configuration file:
Element Description
type Identification of configurable object type
header Contains version number, date of application, user name
sections Related parameters are logically grouped to sections
variables Used to set parameters
comments User comments; they are marked with a # sign
qualifiers Amount of data: KB, MB…; time units: m, h…:, percentage: %
[FSE Pool] <-------------------------------------------- type
[Version = 1] <---------------------------------------- header
[Date = "2005/08/05 15:00:12"]
[User = "[e-mail]"]
# This is where actual parameters start <------------- comment
Name = "My_Media_Pool" <------------ main section
MediaFamily = LTO # AIT | LTO
PoolType = Regular # Regular | WORM | Backup
[DefaultFormat] <---------------------------------- subsection
