I have 4 media agents in total. Two sets of 2 MAs, one set at the primary site and the other set at DR. Each set presents a single disk library at each site (half the storage mounted on each MA with read-only mount points to the other) and a partitioned DDB.
We have 3 or 4 storage policies and all primary copies are hosted at the primary site with Aux Copies (DASH) to DR.
Our link between primary and DR is 800Mbit and we would like the MAs to use a max of 600Mbit for the Aux Copies.
Is there a way for me to restrict the bandwidth used between these 2 sets of 2 MAs to a total figure of 600Mbit? Obviously I can use Network Throttling - I could set the two DR MAs to only allow 300Mbit of "receive traffic" from the two primary MAs which would be a total of 600Mbit. Is this the best (only) way to do it? Ideally I want to say that the entire "group" is allowed to use 600Mbit (rather than specifying 300Mbit for each MA separately). That way, if only one MA is currently copying (which can happen at the end of the Aux Copies as the number of streams remaining is low) it would still be able to use the full 600Mbit rather than being restricted to 300Mbit.
Can this be achieved? I know I can create a "Computer Group" and set Network Throttling here - however, it is unclear to me whether this imposes a dynamic limit "total" across the entire group (eg, 600Mbit which can be split up between the two MAs dynamically) or whether it would just be limiting both MAs to 600Mbit individually. Is the group "smart" in this way? Or is it really just a way to push the same config to multiple machines?
