I have 2 of them and a third on the way shortly... a 4480 and a 4210 using
AIT2 drives... I have never run into an issue with the libraries (unlike our
previous Quantum and Exabyte libraries which were down as often as they were
up.  I would whole heartedly recommend Qualstar for a library.  I wish I
could offer you info on hooking up to a filer but I haven't done it
myself... I do know that when I took some classes for Legato given by
Cambridge Computing up in Boston, they had the libraries hooked up to the
filer via FC and not LVD.  I don't want to toot horns here, but Cambridge
Computer offers great support for stuff like that and it is also who I
purchased my Qualstars from.

Good luck with whatever purchase you decide on.

Subject: [Networker] Tape Libraries

Hello All,

We are running Networker version 6.1.2 on a Sun E250, Solaris 2.6 with 2
P1000 DLT7000 libraries. My question is really more of a hardware question
than a Legato question but I'm posting the question here because I know most
people subscribing to the list have experience with the various tape
libraries on the market.

We are soon going to add a Network Appliance filer with 2TB to our network
and plan to attach a library to the filer for NDMP backups. Our P1000s are
old and have HVD interfaces which is not supported on the netapp so either
we need to convert HVD to LVD or acquire a new library with LVD or FC. I
have priced libraries from STK, Quantum, HP and Qualstar and have found that
the Qualstar seems to offer the best value however I have been warned that
they are not comparable in quality to the other vendors and that there have
been some compatibility problems attaching them to netapp filers. It was
suggested that the problems relate to Qualstar's scsi implementation.

Searching the web, I haven't found any significant amount of negative
information about Qualstar libraries and they really look like an excellent
value so I wondered if any of you on the list have Qualstar libraries and
how you would rate them in terms of reliability, especially if anyone has
one attached to a netapp filer via lvd scsi.

Thanks,
