"Client parallelism" is not global parameter - it applies to each client
resource, (where "client" is a host to be backed up).
Server parallelism is global parameter (except can be "under-ridden" by
Savegroup parallelism - which is another topic).
>From above values - first client to respond will supply up to 8 save
streams, which will fill up first 2 drives (TargSession 4 each). If it has
more save streams than 8 it will have to wait until some finish. Next
client to respond will use up next 2 drives, etc. If drives are full, then
additional clients will stack on top in round-robin fashion, until 48 max
is reached (or savegrp max).
