How to configure bandwidth throttling for optimized duplications for PureDisk and Media Server Deduplication
Description
On the NetBackup media server writing optimized deduplications to either PureDisk or Media Server Deduplication storagepools:
Edit the pd.conf file by uncommenting/configuring the OPTDUP_BANDWIDTH = line to read:
OPTDUP_BANDWIDTH = <value in KB>
Location:
UNIX : /usr/openv/lib/ost-plugins/
Windows : install_path\Veritas\NetBackup\bin\ost-plugins
Note: About the NetBackup media server pd.conf OPTDUP_BANDWIDTH value:
- value is in KB (kilobytes)
- default Storage Server server agent 'maxstreams' value is 4
- (maxstreams value) * (NetBackup Storage Unit ‘Maximum concurrent jobs’ value) * (OPTDUP_BANDWIDTH value) * 8 / 1024 = bandwidth_used_in_Mb(megabits_per_second)
Example for a 10Mb (megabit) per second maximum allowed bandwidth requirement when the NetBackup Storage Unit 'Maximum concurrent jobs' value is 10:
(10Mbps * 1024) / 8 / 10 max concurrent jobs / 4 maxstreams = 32KB OPTDUP_BANDWIDTH
In this example the pd.conf OPTDUP_BANDWIDTH line would read:
OPTDUP_BANDWIDTH = 32
