Yes I did install 7.3 on a T2000... Just for fun really.

I had 4 sata drives in it, so I configured a simple stripe between two
of the disks and put adv_file on it..... I didn't think to tune up the
stripe widths or filesystem block sizes or anything... I just wanted to
see it run before I invest some serious effort. All I have done so far
is let the server backup itself, eg no network or san involved....

Peter, 

I wasn't clear from your posting:  are you saying you installed
NetWorker 7.x on a T2000 (Solaris 10)?  If so, what kind of tape
drive(s) is 
installed onto the T2000?   

Asking because Sun has given me a script to run on one of my NW servers
(Sol8/UltraSPARC III) to evaluate whether NetWorker will run well on a
T2000, and the script pointed out what it thinks are a number of FP 
(floating point) operations being called by nsrmmd.   They may actually 
not be FP operations at all, but showing up as such because of a way
that some processor calls are apparently piped down the FP pipe on the
CPU (according to a T1 engineer at Sun I've heard from on this.)

Thanks!
