Hi,
I've got one of these (below) drive arrays:
http://www.acc.umu.se/images/archive/20020926-RSM2000/DSC02816.t.jpg
I.e. *just* the drive assembly. But, from digging around,
I *think* it is not just a JBOD (like a D1000) but, rather,
requires "something else" in order to make the electrons
do their magic dance.
Of course, I don't *have* that "something else"! :-(
*But*, I would be quite happy using it as *just* a JBOD!
My question(s): the box has what appears to be a HD SCSI connector
on the back of it -- though it doesn't carry the expected SCSI
logo (or any other similar labeling). Is this, in fact, a standard
SCSI i/f? Or, is it some bastard interface intended to talk to
that "other box" and coincidentally using a SCSI-ish connector?
If it is a SCSI i/f, is it HVD, LVD, wide, etc.? (I ask because
I have had all sorts of trouble trying to talk to a D1000).
Thanks for any pointers!

That's an RSM 2000.
A controller box with up to 5 trays.
It uses differential scsi to the controller, as well as
from the controller to the array's.
Each
array can be used as a JBOD if you like.
4.3 GB disks were used if I remember correctly.
The RSM was between the SSA10x and the A3500.
Regards,
Ed

Looks more like RSM 214, or 219 (IMO)

http://sunsolve.sun.com/handbook_pub/Systems/SSA_219_7Slot/SSA_219_7Slot.ht…
Than the RSM 2000

It looks like the RSM2000 is that "other box" I was alluding to
(more of a *controller*) while the SSA21[49] appear to be the
"drive trays" that connect to it.
I pulled the I/F card and checked the P/N against the P/N listed
for the 219's I/F and they agree (amusing that the silkscreen on
the PCB is "UNISYS"). Likewise, pulled the fan assembly off and
verified that it's P/N agrees with the one listed for the 219.
The actual array has a P/N of 595-4088 and claims to be
"Style OSM3000-SD2". <shrug>
The RSM2000 page mentions diff SCSI cables (to the arrays)
and the 219 page describes a "differential interface" so this
seems to confirm Edward's previous comments.
But, I'd still like to know if it is LVD or HVD (I don't have
a HVD SBUS card but *do* have LVD)... ?
Thanks!

So, what I have is a "tray" (?)
It uses differential scsi to the controller, as well
as
from the controller to the array's.
Yes, but is it LVD to the tray or HVD?
E.g. I have found that the D1000 is *H*VD -- so my *L*VD
controllers won't talk to it. :-(
Each array can be used as a JBOD if you like.
Ah, thanks.
4.3 GB disks were used if I remember correctly.
These are 9's, I think. But half height so I can't just pull
the drives and stuff them into something else...
The RSM was between the SSA10x and the A3500.
Thanks!

The two boxes currently have seven 9G drives, each. I have a box

Because I don't have the controller that they attach to! :>
So, they are, at best, JBOD's. What I *do* with those
(e.g., software RAID) is a different issue.
Why put data on them if you're not
all that concerned about it going away when one of those old drives goes
tango uniform (toes up) ? With that many independent drives, couldn't you
make a really big RAID-5 out of it?
The data I want to store on them is already backed up on
MO, CD-R and DLT media. Getting the data onto a drive array
is just one of convenience. And, while 15x18G drives waste
more electricity, BTUs and *space* than a single 300G *IDE*
drive, couldn't you argue that damn near ANY of the machines
discussed on this list could be more "efficiently" replaced
by something newer, smaller, faster, etc.? :>

Heh...
I've got a box where I'm building up a RAID array w/ 2G drives!
Only because I got given a whole pile of these for free. A while back there
were a whole mess of 9G SCSI-wide drives around in the surplus market, and my
inclination is to eventually get a hold of some of those and upgrade the
array to that size, eventually, when I can accumulate enough of them. I
really can't afford to invest in them if I had to buy them, though.
I'm mainly just inclined to use what I've got, I guess.

Yup. Unfortunately, the drive array in question has half height
slots. So, I can only stuff 7 drives in it. The flip side of that
is the drives that *are* in it are all half height. :-( They would
have been nice to stuff in the SSA 101 (?) I have. (But, I'm not sure
that array can handle 9G drives??)
