On May 9, 1988, AT&T announced the third release of SCSI
peripherals for the AT&T 3B2 computer family. Included in
the announcement were:
Differential Host Adapter - Provides a differential
SCSI interface for 3B2/500, 3B2/600, and
3B2/700 Computers.
DM/300S - A package containing 1 300 MB (formatted)
disk with a built-in single-ended SCSI
interface.
DM/300DS - A package containing 1 300 MB (formatted)
disk with a built-in differential SCSI
interface.
9-Track - A package containing a 1600/6250 bpi, 125 ips
9-track tape drive with a single-ended SCSI
interface.
9-Track - A package containing a 1600/6250 bpi, 125 ips
9-track tape drive with a differential SCSI
interface.
The 9-track tape drive provides auto-loading
of tapes and is packaged in a table-top
package measuring approximately 9"H x 19"W
x 24"D, with a weight of 85 lbs.
In addition to the new hardware supported, software support
for mirroring of disks drives was also announced. The
mirroring software allows mirroring, on a partition basis,
of any two partitions on any two SCSI disks. The software
works on any 3B2 computer with the UNIX(R) Operating System
V, Release 3.2.
Also announced was support to allow multiple computers to
share a common differential SCSI bus and share access to the
peripherals on them.
As with past announcements to this news group, in addition
to announcing new products for the AT&T 3B2 family, we are
interested in any experiences, good or bad, you may have
with the AT&T 3B2 SCSI equipment. (Any comments on problems
should include as much detail on system configuration as
possible, including the UNIX(R) Operating System version.)
We are interested in hearing of the applications you run in
which you need the capabilities of SCSI, how well SCSI meets
your needs, and if the performance and functionality were as
expected. Also, what new features/peripherals would you
like to see provided in future releases and how would they
help you?
We are also interested in comments on how knowledgeable the
sales staff was, how long it took to get the equipment once
it was ordered, and how easy it was to install.
We cannot usurp the role of the support organizations to
directly solve any problems. We may be able to respond to
general questions on what was done, and perhaps why it was
done, in our implementation.
However, we can promise that all comments will be carefully
considered as input to future releases of the SCSI products,
and this will hopefully make upgrades to your system
function better for you.
