Hi Dan, I dont know if my rsponse on this is still relevent.
First of all there are 2 kinds of NDMP backup. Local NDMP in this filer accesses the library locally via scsi or fc Remote NDMP one filer sends the backup data to library connected to another filer When you send the backups to library connected to nbu media server it is called 3 way (which is a form of remote) ndmp. Now coming to performence on isilon It will be much better almost 10times of what you are getting now as it is going to be disk bases however connection should be over 10Gbe also i would say decide whether you want backups or archive....if u just want to archive go with data domain dd 990 archiver which gives arhives with dedupe.

This works reasonably well and I get reported throughput of 90MB/sec on multiple streams. I'm looking at buying an Isilon system (3x X200), and am considering whether to continue to use 3-way NDMP (and buy isilon's fibre channel backup appliance to do so), move to 2-way NDMP, or possibly something else. In particular I'm wondering about what kind of performance I can expect with 2-way NDMP. ...and as i read some docs I think I've gotten the meaning of 2-way and 3-way NDMP confused. current setup: EMC NS120's are connected by fibre channel to the tape drives. netbackup server is only doing control, no data traffic goes through the netbackup server. proposed setup: isilon sends data over ethernet to netbackup server, which writes data to tape via fibre channel. -- Dan Pritts ICPSR Computing & Network Services University of Michigan +1 (734)615-7362 _______________________________________________ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
