That performance is superb!! To get that, did you go with the defaults, or was any significant tuning done?
Were there any filer settings that needed to be changed? Also, was there any network gotchas that you encountered? Thanks so so much!

There is a significant ethernet workload on the TSM server because I am backing up 6 Netapp filers simultaneously. Sar shows 100% cpu utilization on the TSM server during the processing due to the high ethernet load. I have one 50GB backup that takes 30 minutes (1.6GB/minute) Make sure you are using TSM 5.4.1.1 or later because it addresses some NDMP bugs in 5.4.1.0 You might check with your networking folks to ensure that all ethernet settings are correct.

The backups are NDMP images, with the TOC. The TOC goes to a separate disk storage pool. I am experiencing terrible performance. In the region of 2 MBs for backup and 0.2MBs restore!!! Have checked the basic settings tcpnodelay etc and disk performance etc... Can anyone think of anything, (sorry, its expansive!!!) Also any real world experience when it comes to performance? expected throughputs etc And how to get them!!! Ian Smith --- This e-mail may contain confidential and/or privileged information.
