How may streams are you running concurrent on the data domain ?
What DDOS version are you running ?
Do you have theb BOOST license ?
From my experience, even thou Dell-EMC claim they can have many hundred concurrent connection, the injection max is reached around 60 concurrent connections.
One indication of bottleneck is the average transfer speed, if all backup to data domain somewhat have the same transfer speed in KB/sec, then for sure there is a infrastructure bottleneck.
Hi Nicolai,
When affected policies interleave maximum streams is 48 or 24 per policy. Don't have Boost licence, DDOS version is 6.1.2.30-615547.
Nicolai is there any possibility to configure settings for policy that IF policies interleave for some reason that the policy B that is still ongoing(A policy starts earlier than other) recovers its speed to maximum?
This is what we are getting in output of finished job(A policy):

It seems that streams from policy A cannot achieve their maximum potential if policies interleave, is this dependant on hardware?
