Setup guide

Each partition managed by the Bandwidth Manager must have a [Device]
section associated to it in the /usr/discreet/sw/cfg/sw_bwmgr.cfg file.
To add a new device to the Bandwidth Manager:
1 Open the /usr/discreet/sw/cfg/sw_bwmgr.cfg file in a text editor.
2 Add a new [Device] section at the end of the file, using the following
syntax:
TIP You may also copy and paste an existing [Device] section, and change
its parameters.
[Device<device_number>]
Path<path_number>=<device_mount_point>
TotalAvailableReadBandwidth=<total_read_bandwidth>
TotalAvailableWriteBandwidth=<total_write_bandwidth>
DefaultReservation=<default_reservation>
where:
■ <device_number> represents the number of the [Device] section,
starting at 0. For example:
[Device0]
■ Path specifies the partition's mount point. Since a partition can have
several paths, <path_number> represents the number of the current
path, starting at 0 for each device. For example:
Path0=/mnt/XYZ
Path1=/usr/local/ABC
■ TotalAvailableReadBandwidth represents the estimated total
reading bandwidth of the device, in megabytes per second. Based on
this value, and on the amount of active reservations for the current
partition, the Bandwidth Manager decides whether new reservation
requests are granted or rejected. For example:
TotalAvailableReadBandwidth=200
■ TotalAvailableWriteBandwidth represents the maximum
estimated writing bandwidth of the device, in megabytes per second.
If this parameter is not specified, its value defaults to the value of
TotalAvailableReadBandwidth. For example:
TotalAvailableWriteBandwidth=150
