I have been using DSSU since 5.1 came out.
But I have primarily used it for very slow clients so that I didn't block my
tapedrives with these backups.

It has been working really fine, except the lack of configuration and
performance/tuning. And it has been really easy to use.

I have upgraded to 6.0 MP2 now, and there are a lot of nice new stuff in 6.0
regarding DSSU, but I haven't had that much time to check it out. But it
seems to perform better and there are also more configuration options. Not
that I couldn't make a 1 meter list of things I would like to have.

DSU's I have only used for testing, so no comments from me on that. But when
I looked at it DSSU seemed to me to be a much better solution. At least in
our installation.

Have never used VTL, so also no comments on that.

Subject: [Veritas-bu] DSSU/DSU experience

We're in the process of rearchitecting our BUR infrastructure. The most 
profound change will be the addition of disk storage, as we are 100% 
tape, right now. We're considering a few different disk technologies, 
such as VTL, DataDomain NAS heads, as well as traditional DSU/DSSUs.

I've heard anecdotal evidence that DSU/DSSU functionality in NBU 5.1 is 
less-than-stellar. Would anyone care to share their overall experience 
with  disk storage?

Thanks,

Steve
