That's not a cluster, but rather a normal deployment.
 
assuming the media servers backup their respective sites only, and you
don't want to backup a client at site A to a media server at Site B, you
create a Storage unit on each media server, then create two storage unit
groups, one which includes all Storage Units belonging to the Media
servers at site A and one for Site B, create Policies for each site,
point the Policies to the respective Storage Unit Groups and Bob's yer
uncle. Not sure if tha't's Bob Stump or bob944 though.
 
No extra software required....it's the way NBU works.

        Ok here is my setup and what we want to do.  We have 1 master
and 6 media servers. 3 media servers are site1 and 3 at site2 with 1
master controlling both sites (their is a 4gig pipe connecting the 2
sites) . At each site we have 2 Storagetek L700 libraries and a EMC CDL
740 split into side a and b.  We want to move the robotic control to the
master for the L700's and the CDL and then have each media server see
all the libraries at their site. We want the master to load balance work
automatically between the media servers so not one media server is
overloaded while another is idle.  This will allow us to loose a media
server without loosing robotic control over a device.
         
        Does anyone have a setup like this where they are clustering
servers together? What software needs to be in place to do this?
Thoughts? good or bad?.
