Hi all

I am running TSM 6.2.1.1 on AIX V615 in a LPAR on a P770.  The LPAR
has 6 shared CPU's, 12 virtual CPU;s, and 64GB of memory.  There are 2
VIO servers with 4 fiber channel connections to XIV storage for the DB
and LOG, and 2 10Gbit Ethernet in each VIO in an Etherchannel
configuration.  The storage pool is on Data Domain DD880's, 2 per AIX,
1 per instance.

I am seeing consistenly poor performance from this setup.  I have
tested network from VIO to cloud, and LPAR to VIO, which seems fine.
I tested LPAR to Data Domain, and things seem fine.  But, when backups
are running (and I only have a few nodes there yet, this is a new
setup), TSM doesn't seem to want to go over 20 to 30MB/s throughput.
I tried backing up the TSM server over lo, and that was a little
better at 50MB/s, but not screaming.  I tried using chunk of SAN as a
disk pool ahead of the Data Domain, no change.  I am at my whit's end.

If anyone has any ideas, please let me know.  Thanks.
