Client Parallelism is a hidden option in your client resource. So if you want to use 3 devices parallel with that client, set it to a value of 12. The other question is, can your server create enough IO to serve the possible native writespeed of your DLTs.

Device parallelism is not a hard limit, it is just used for loadbalancing.

You should set your server parallelism general to a higher value. Better set it to 256

Client Parallelism?  Is there an option I don't see it in the client record.
Device parallelism is 4 per drive. (this was the default)
Server parallelism is 24 (I changed it by guessing 6 drives at 4 makes 24)

Thanks, Rob.
