Hello Rafael,

We run a three frame SP system with 2 wide nodes, 12 thin nodes and 7 high 
nodes. One of the wide nodes is the adsm server and the rest of the nodes are 
adsm aix clients. The Control Workstation and the adsm server node also has 
client code on them. 2 3590's are attached to the adsm server node (though we 
are likely to get a 3494 and two more 3590s in the near future. Backups are 
performed over the SP Parallel Switch and through put is very satisfactory. 
(SAP R/3 using backint can backup at around 25 GB an hour).

If you want more detail of our setup feel free to ask. 

Best Regards,
