| Hi Kelvin,
The KAV30 only supports the Digital SCSI disks that are listed as being
supported by VAXELN 4.2. The SCSI drives supported by the KAV30 are:
o RZ22
o RZ23
o RZ23L
o RZ55
o RZ56
o RRD40 CDROM
o RX23
Digtial recommends that only devices from the above list
be used. The use of any other device is not recommended or
supported by Digital.
The above information can also be found in the
VAXELN KAV TOOLKIT EXTENSIONS FOR VMS V1.0 release notes.

| 17.2 | Rack mounting? | MIACT::WALLACE | john wallace @ bbp | Thu Aug 29 1991 16:16 | 18 |
| What about rackmounting?
I have an enquiry from a customer who wants a transportable
rack-mounted setup with local hard disk and floppy. They want a
standalone ELN environment with substantial local read/write storage,
preferably all in 1 Eurocard (or whatever) rack. Is there a reasonable
way of doing this with existing options? The likely sales volume is low
so custom EIC solutions may not help.
I believe there are rackmount kits for some of our 3100 series systems,
although I can't find any details now... Are there rackmount kits for
the equivalent SCSI expansion boxes? This wouldn't be ideal (total
overkill) but might at least give them a supported solution.
Alternatively is there somewhere else I should ask?
regards
john

| Well if you want to use the KAV30 you must have some VME connectors in some
sort of enclosure to supply it with power. Then you would need some Disks which
could be plugged into this VME connector - those disk do not exists (yet)
from Digital, so I can't see how you would get those options, since any disk
not supplied by Digital is not supported by VAXELN.
How about an entirly differen processor, or rack-mount processor, EIC Munich
offeres (I hope I am right) a rack mount VAX6000 with some local storage,
how about that?
Julian.

| 17.4 | Support is optional in this case | MIACT::WALLACE | john wallace @ bbp | Fri Aug 30 1991 20:06 | 31 |
| Thanks Julian.
Neither the rackmount 6000 nor the smaller cheaper rackmount 4000 are
appropriate here. The whole system needs to be movable without lifting
gear. So a VAX in a BA23 box just *might* do it, e.g. an RTVAX3200.
Anything bigger won't meet the spec. Anyway none of these have a
VMEbus for the customer's home-made VMEbus I/O.
This particular customer knows DEC kit better than most DECies. They
buy DEC kit, typically from distributors, and add specialist third
party stuff - ruggedised tapes, disks, special-purpose I/O. It's for
their own use not for resale so it's fairly low volume. Because of the
amount of obscure third party stuff it usually ends up on self
maintenance. So "support" is not really an issue - though this is not
an approach I would generally recommend!
If they can buy something from DEC at a reasonable price that does the
job, they will - they like the KAV30/ELN concept, having already used
Qbus RTVAXes. But if the only DEC content is a KAV30 and the goodness
of using ELN software, there's a risk the whole business may go to a
VME vendor of their choice.
Are we really providing an RTVAX on VME with a SCSI controller and
nothing useful to connect it to, either of our own or by referral?
(Then why all the fuss about the "DEC's Open Advantage"? :-) The
Infoserver people are willing to qualify 3rd party SCSI I/O. The IEZ11
is a qualified third party SCSI-GPIB adapter. Are there any plans for
the VME/realtime market segment?

| If we don't have a SCSI for VME offering and no apparent plans for one,
is there any interest in qualifying the integrated disk systems
available from VME rack suppliers like BICC/Vero and Schroff - you buy
a VME rack and it comes with a drive already in it.
Please?
regards

| Hi John,
It's really a question of support, A number of vendors have "packaged"
Digital SCSI drives for VMEbus.
I'm not sure what the "official" position is on the support of these
drives.

| John,
I do have the first RX23 integrated in a VME enclosure by a company
called PEP Modular Computers. They are also in UK. The contact is
Peter Blewett, phone (0273) 771-297
They have been in contact with people from Digital before and know
about the enclosure they built for us (Graham McKenzie @BBP) owns
one of them.
Another company working on such solutions are IRTV in Germany.
Contact Mr. Hueller, (0049) 40- 2980140
I requested from them a RZ35 integration, but did not get a firm
response yet. They are working with non-digital disks.
Regards,
Wolfgang
