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.

Subject: Re: [Veritas-bu] NDMP/isilon throughput question
Currently I have two EMC Celerra NS120's, and I use 3-way NDMP
direct to
tape to back them up. 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.
