On commodity Intel/AMD equipment on an 8 node 5TB RAC cluster only using 6
nodes to run the backup from, we maintain 45MB/sec on a 1Gb public NIC per
backup node. When networking/App is not busy of course we can stream at
65MB/sec - 80MB/sec.

Just as a point of reference - we are getting throughput of about 30MB/sec
(~100GB/hr) from our production LPAR to the backup system. I believe this is
over a dedicated gigabit connection going to the Netbackup disk staging area
(not directly to tape).

Turn this into a numbers game - how much data, how often does it need to be
backed up, and how long can it take to back up? Based on that, you can make an
informed decision about whether an LPAR can support the IO.
