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. -- Andy Carlson --------------------------------------------------------------------------- Gamecube:$150,PSO:$50,Broadband Adapter: $35, Hunters License: $8.95/month, The feeling of seeing the red box with the item you want in it:Priceless.
