You can certainly use a DLT7000 on an HP 3000.  I believe there is a patch
available to make it work under 5.5.

It should work with TURBOSTORE, but I do not speak for HP.

As for managing it, it depends on what you mean.  I suspect you are talking
about a DLT autoloader.  If this is the case, then currently whilst you can
write to the drive directly from the HP 3000, the latter cannot control the
robotics in random mode. You have mentioned a few other products that can
manage the autoloader attached to a UNIX box, but that way, you need to
send the entire backup over the network.  This will require a minimum of a
100BaseTX network with no other activity, at all, to come anywhere close to
keeping the DLT streaming.

Here are some numbers to keep in mind. A DLT7000 writes at 5 MB/s in native
mode and up to 10 MB/s in compressed mode.  Whilst you will never see that
latter figure, you should be able to attain somewhere between 7-8.5 MB/s,
sustained.  This is about 50-100% faster than what a 100BaseTx network can
sustain.  So you want to connect via SCSI to the DLT drive. BTW, these
figures fall under the YMMV caveat.  Things that influence them are:  disk
speed, channel contention, compressibility of the data, etc. . .

With Hiback, you can connect your 3000 directly to one or more drives on
the autoloader and you can use either a UNIX or even an inexpensive NT
workstation to control the robotics of the DLT autoloader.  Hiback on MPE
sends a request to Hiback on NT or UNIX to mount a specific tape on a
specific drive and then Hiback on MPE performs the backup directly to the
tape drive at SCSI speed.  This way you get the best throughput, you do not
impact the network and you get full library management.

Does anybody use DLT 7000 on an HP3000?
Does it work with TurboStore 24X7?
I was told that the software to manage it must run on a Unix box (something
like Legatto Networker of OMNIBACK?
I will appreciate any feedback.   Thanks
