I don't think it can be done by USB. The SAS-to-USB chips operate in
"mass storage" mode, suitable for SAS hard drives. The LTO drive will
need an adapter that operates in SCSI emulation mode. I don't know of
any adapters that aren't strictly for hard drives, but maybe there are.
Another approach is to use a Thunderbolt port instead. Thunderbolt is
essentially an encapsulation of PCI-e. There are many Thunderbolt PCI-e
Expansion chassis available that are simply one or more PCI-e slots
connected via Thunderbolt (but with their own power supply). You can
insert a PCI-e SAS controller in the expansion chassis and the server
will treat it exactly like one of its own PCI-e slots, so the OS will
see the tape drive in exactly the same way and so then would Bacula.

all,<br>
<br>
This might be considered slightly off topic but has anybody
tried <br>
installing USB3 PCIe card in an external LTO tape drive?<br>
<br>
Many models appear to have 2 slots with only one occupied by
SAS by <br>
default, e.g:<br>
<a
href="https://www.bechtle.com/de-en/shop/quantum-lto-7-hh-sas-external-drive--4038311--p"

class="moz-txt-link-freetext">https://www.bechtle.com/de-en/shop/quantum-lto-7-hh-sas-external-drive--4038311--p</a><br>
<br>
The idea would be for the tape drive to operate via SAS 99% of
the time <br>
but occasionally move it elsewhere and easily access via USB
(from any <br>
desktop or laptop).<br>
<br>
Somebody has done it before on a factory level:<br>
<a
href="https://www.fujifilm.com/in/en/business/data-management/datastorage/lto-tape-drive/brochure"
rel="noreferrer" target="_blank" moz-do-not-send="true"
class="moz-txt-link-freetext">https://www.fujifilm.com/in/en/business/data-management/datastorage/lto-tape-drive/brochure</a><br>
but I would prefer not to be limited and locked to this one
particular <br>
model + software.<br>
<br>
I'm assuming that I should still be able to run Bacula with
the above?<br>
<br>
Any advise?<br>
