I'm fairly sure it was set up that way to have redundant power (from

It has three connectors on the front; two 50-pin high-density

50-way connectors are DSSI, and the RJ11 is for a terminal?
Yes, it is. Two of them, in fact. The module is in the top, inserted
RZ29B-VA, it says on the outside.
Ok, so I shouldn't just dump it, then ;-)
To be honest, though, I don't think I want to keep it. I have two
MicroVAXes, a uVAX-II in a BA23, and a uVAX 3100 (DV-31AT1-A, on the
label on the back). Both have internal drives. I'm not likely to use
either for anything serious, and I need the space the StorageWorks unit
is occupying.
on my VMS
systems. I've got a BA350 attached to the PWS 433au I use as
a server via a Narrow SCSI card.

2 x SWXBP power supply
Unless the HSD10 is pulling a LOT of power, you should be able
to get by using just one of these, while having two gives you
redundant power, I prefer to have the slot open for another device. 1 x HSD10-AA
DSSI-SCSI controller (what does this do, exactly?)
As mentioned, it lets you use SCSI devices on a MicroVAX with DSSI. 1 x 70-32155-01
8-bit interface (SCSI? or what?)
Does this plug into the end opposite the powersupplies? It
sounds like you've got a BA356 shelf. If so, I'm envious,
I've only got BA350's, the BA356 supports both 8-bit and
16-bit interface modules. Oh, yes, if we're talking about
the same thing, it's SCSI. It's a High Density 50-pin
connector, right? from the front, same as everything else. Ah, I guess
you're thinking
in terms of a horizontal rack-mounted unit (the other one that
the
VAXes had was mounted like that); this unit has the extra pieces for
floor mounting and (AFAIK) doesn't have the brackets for rack mounting.
Does it make sense to have both the 70-32155-01 SCSI interface and the
HSD10-AA DSSI/SCSI unit in the same shelf?
1 x RZ29B 4.3GB
fast wide disk
RZ29B-VW? 1 x TLZ06 DDS
tape drive
You have an SBB, with a TLZ06 in it? Now I'm even greener with
envy! I've only got disks. Plus, I don't have any of the nice
enclosed models with doors.
I should have mentioned it's a BA35X-MD box.
These are actually the fans on the back of the shelf. The
good news is they're the good dual-speed ones that support
the 7200RPM drives. >It came wih a MicroVAX some time ago, but I've
never used it.
Anybody
want it, for a
suitably low price?
You might just want to keep it... I really like using StorageWorks
If you want, I should be able to dig up all the manuals on this, as I
think
I've got PDF's of them.
I'll have another look round, where it came from. They may still be
there.

I'm wonderind if the HSD10 needs to be cabled to it, or if it is not used. There is a
third possibility, the shelf might be split into two segments, one acting as a DSSI device
and one acting as Narrow SCSI

If you got the cabling sorted out, it would be an excellent 2nd disk and backup device for
the 3100 (minus the DSSI converter). Actually if you pulled the DSSI converter it should
work on one of your other systems such as your SGI Workstation.
