NBU AIR replication bandwidth throttling.

[Masami_Katsuno]

Hi Experts,

Can NBU controll bandwidth of AIR Replication?

NBU can control the bandwidth for backing up to Cloud. How about AIR?

Hi,

You should consider following technote:

To limit the bandwidth used by replication there are two ways

The OPTDUP_BANDWIDTH limit (in the pd.conf file) will do it per stream but generally it is the total that needs to be resticted and not just one stream

So for that you need to edit the agent.cfg file (/disk/etc/puredisk/agent.cfg or equivalent windows equivalent)

In that file is a BANDWIDTH_LIMIT value which is set to 0 by default

It can be changed to a suitable value (kb/s - but test ot out as it can give odd results) and this controls the total bandwidth used for opt dupe (and hence AIR replication) for that server

There is no global value for all servers so if you have several you just need to balance them out

Hope this helps
