Hi Chester,

It won't hurt your dedupe or backup performance. It's even best practice.
That way your clients will have a 2nd storage node to use in case the first one 
is unreachable.

We use three SN per zone in our environment and each SN is 'present' in each 
pool.

Subject: [Networker] DD Boost Devices in Same Media Pool, Multiple Storage 
Nodes?

Hello,
I'm using DD boost, nw 7.6.x and am trying to make my environment more 
resilient to failures, including backup server failures.  Does it hurt dedupe 
performance, or backup performance, to have a media pool have data domain 
devices attached to 2 different storage nodes at the same site?

For instance:
1 physical site
Group1 writes to MediaPool1, has roughly 30 clients in it
MediaPool1 has devices that are attached to StorageNode1 and StorageNode2

What I'm trying to protect against is if StorageNode1 physically goes down 
during the night that StorageNode2 will pick up the slack.

Thanks.
