R-Squared, in Colorado, and Eli Heffron's in Boston, and Polaris in
Boston all have been good suppliers for us. We had an Exabyte from
R-Squared that worked quite well for over a year: it got flood-damaged
and is now replaced with one from Polaris, which also works quite
Everybody basically repackages the same units for Exabyte drives. In
your shoes, I would look for price, familiar service, and a local
hot-swap. Also, make sure you have the right SCSI cables for your
system (this lead to some confusion when I bought the R-Squared box,
which used D-50 connectors).

I am using HP DAT drive 35480A (2 GB, plus compression), and ApUnix's "ht" device driver. After a few initial bugs, I am very happy. It supports fixed and variable block mode, compression and non-compression (although I am not using compression). Throughput is non-compressed modes is still limited byt the 185 KB/sec transfer limit. ApUnix can be reached at 1-800-8AP-UNIX - Doug Neuhauser, firstname.lastname@example.org, 510-642-0931

Buy your drive from Apunix. They are generally competitive and they provide excellent support, including a device driver and miscellaneous software.

In the past, I have used a DAT drive from Box-hill.
They supply the driver, and if you are running 4.1.3, I think their drivers are dynamically loadable, so you don't need to rebuild your kernel.
We never had any problems with the drive; Ofcourse, we only had it for a few months.

We're also using 4.1.3, and we just got an ArchiveST 4000DAT drive. It's made by Maynard Electronics, which is apparently a British firm(?), part of Archive Corp. (I'll give the addresses in a while). It wasn't what we originally tried to get, but the wa
It required an addition to the /sys/scsi/targets/st_conf.c file, but that's described in the Installation Notes.
According to my notes, it cost ~$2200, but I don't know what discounts were involved.

Hope this helps you!

Exabyte is not DAT, it is 8mm. The Exabyte 8200 (2.3Gb) works well under SunOS 4.1.1 (and presumably with later releases) with no kernel mods or added drivers.

I have been using an Archive DAT for the past six months or so without a hitch on a 670 running 4.1.3. To add the drive I modified:
and remade the kernel. After doing so, the following message is displayed at boot time.
Jul 3 22:50:26 electron vmunix: st1: <ArchiveST 4mm DAT/DAT-DC>
The version of the drive I use will write 2GB of data on a 90 meter tape, there is a newer version which I (think) doubles the storage capacity.
