Setup guide

To set up bandwidth reservation for a group of applications:
1 Open the /usr/discreet/sw/cfg/sw_bwmgr.cfg file in a text editor.
2 In the [Groups] section, add a line for each group of applications you
want to define. The syntax of the line is as follows:
<group_name>=<application_name> <application_name>
where:
■ <group_name> is the custom name of the group. The group name
must not contain spaces and must not be the same as one of the
predefined application names.
■ Each <application_name> represents the name of an application
in the group. This parameter can take one of the following predefined
values: “inferno”, “flame”, “flint”, “smoke”, “imcopy”,
“stonifiseTool”, “publishTool”, “S+W Server”, “IFFFS Wiretap Server”,
or “IFFFSTool” for other Visual Effects and Finishing command-line
tools.
For example:
[Groups]
IFFFSTools=imcopy stonifiseTool publishTool
3 After you have defined the group, go to the [Device]section for the
appropriate partition and add a Reservation line for the new group.
The syntax is the same as when adding a reservation for a single
application. For example (using the “IFFFSTools” group from the previous
step):
Reservation1=IFFFSTools 50 50
4 Save and close the configuration file, and restart Stone and Wire by
typing:
/etc/init.d/stone+wire restart
For additional information on all the parameters in the Bandwidth Manager
configuration file, and for a list of application names you can use when
defining reservations, see the comments inside the configuration file.
Monitoring Partition Fill Rate
As each disk in a storage array gets filled near capacity, its overall read and
write performance decreases once a certain threshold is reached.
