No, these RAID 7 disk array platforms are not available from us here
at the new Wang Labs.  You would have to get them directly from Storage
Computer in Nashua, New Hampshire, or via their European headquarters
in Frankfurt, or their European/Asia/Pacific distributors.  Here at the
new Wang Labs we are reselling a RAID 3 from another major vendor, because
the architecture more closely matches that of our VS minicomputers
(both those already installed and the new VS high-end models that have
been coming out recently.)   I'll be happy to find some technical RAID
reports on the Wang VS RAIDs for those people interested.

Actually they've published a number of technical articles in the
literature.  They seem to prefer to publish more technical material,
rather than marketing blurbs.  There have been some recent, favorable
reviews of their products in Corporate Technology Review, Open Systems
Today, and iX magazine from Germany.  People interested could probably
get copies by calling them at 603-880-3005.

In general, they seem to prefer demoing their products at user group
meetings, rather than sending out press releases.  They have recently
had booths at the Banyan, Wang, and Sun users groups meetings, among
others.

The 386-25 I bought several years ago (for a bargain price at the time)
finally had an incompatibility with some software and hardware I wanted
to run.  A BIOS upgrade was chancy, and would cost $ 100.  So I opted
for a new motherboard, a 386-33.  My memory and math co-processor were
adequate already.  The total upgrade cost was $ 185.  And I can use the
old board to upgrade a '286.  I'll bet my total cost for the two boards
over the 4 years or so was well below the cost of a premium board back
then (which would be obsolete technology by now).  

For the same reason, I wouldn't pay more than $ 100 or so premium for
an "upgradeable CPU" motherboard.  Bare '486 boards (no memory or
CPU) are only $ 120 now.  If it turns out I have to upgrade the BIOS
or CPU a couple of years down the line, it almost certainly won't cost
more than that.

Please keep in mind that only RAID Levels 0 through 5 are standardized.
Neither RAID 6 nor RAID 7 are standardized in any way. I have a Mylex
RAID at home which claims to be switchable to RAID 0,1,5,6 and 7.
They define RAID 6 as mixture of striping and mirroring, and RAID 7 as 
just a buch of disks (JBOD). While StorComps approach to RAID had a
couple of advantages, it is - to my mind - an implementation of a RAID
4, improved by large caches, thus trying to eliminate the bottle neck of
a single parity drive. Async transfers from the cache to the parity drive or
from the cache to the data drives have some disadvantages - for example
in a power fail situation. StorComp's RAID relies heavily on such async
transfers. You really need an uninterruptible power supply if you think
of using this disk array. At the moment I am evaluating RAID
implementations for a German unix magazine. I have had Storcomp's RAID
at home and think it performs nicely as long as there are enough hot
standby drives available. If a drive fails and if there is no hot
standby, performance will drop dramatically. There are a couple of
advantages the Storcomp RAID offers, but to my mind it is just a vendor
specific implementation of RAID 4 (it need not be bad just because it is
RAID 4).

Do PCs with local BUS video designs generate more heat than those
without?

I was recently at a local Micro Center looking for a machine with
local BUS configuration.  A helpful salesman said they did not yet
offer one and further added that such PCs have a tendency to create
excess heat because of that configuration.  Why would that be?  He
further suggested that this could possibly cause problems for the
machine after a year or so.

That's a new one on me - at least a dozen mail order clone vendors now
offer PCs with local BUS video.  I would think they'd be doing
something right rather than setting themselves up for a warranty
nightmare.

OK, now that the motherboard issue has been hashed-out, we can get on to
the second part of the question - actually testing the DMA capability.

The Adaptec controller has a DMA transfer speed test in it's BIOS.  Jumper
the DMA speed on the board for the slowest setting (J5, jumpers 12 and 13),
boot DOS (from floppy!), invoke 'debug', and type 'g=DC00:9' (the DC00 value
depends in the BIOS base address jumpers).

You'll get a signon from the DMA test with instructions.  If the test works,
rejumper to the next faster speed and retest.  After testing all four speeds,
jumper the board for the fastest speed that passed the test.  I've seen some
motherboards that had problems at intermediate speeds but worked at higher
speeds.

I think The spec you should be looking at is the Mean Time To Failure (MTTF).
This is the mean time to the first failure of a product and is usualy much 
smaler than the MTBF. Other Specs you should look at are the Mean Time To 
Repair (MTTR), the mean time it takes to fix a failure. These values give 
you a much more realistic picture of a products reliability.

I once worked with a QA engineer who told me all about the tricks he was taught

I'm running two 3259Ts in my 386-SX20 clone on an Adaptec 1520B.  Simply put, I love
them.  They installed like a dream, they haven't given me any grief of any kind, and
according to the benchmark I ran, they're giving me close to 800kbs transfer.  The
first has been in the machine for longer than I can honestly remember (close to 2
years...?).  I added the other about 6 months ago.  Both were used drives so I have
no idea of how much additional use they got before I put them in.

As the poet says, "your mileage may vary...".  But "rodents"?  Fie on thee...!

Here's the information straight from Adaptec (not verbatim): the 1542B
will support SCO UNIX 3.2 ver 2 with the ASW-1450 (ver 1.0) driver
package. The 1542B will support SCO UNIX 3.2 ver 4, SunSoft/Interactive

I suppose that EMBEDDED SUPPORT means that you don't need any extra

Subject: SCSI/CAM Request For Information

Date: Wed, 16 Dec 1992 19:14:30 GMT

I am working on a SCSI driver for the NCR53C720 product.  It is a dual
channel board.  I have read the SCSI/CAM specification and think that
would be the way to implement a driver.  I am doing the driver on a
System VR3 platform.  I have the following questions regarding the init
portion of the modules.

1)  The spec talks about a configuration_driver().  What is the format of
    this and how is it invoked (directly from the kernel or from the XPT)?
    This module sets up the cam_edt[] table.  How is the relationship
    between the physical device parameters (SCSI ID, device type, etc)
    and the logical device name made (is the information contained in
    the cam_edt[] and if so, who sets it up?)?  How does the
    configuration_driver() know about the existence of any SIM's?

2)  How does the peripheral driver or the XPT access the cam_edt[] or the
    cam_conftbl[] (are they both global)?

3)  When performing the auto-scan, is the device existence tested for at
    the SIM level or does the XPT set up a Test Unit Ready CCB and issue
    it to the SIM?  Is this information passed to the configuration_driver()
    or is the cam_edt[] writable by both the XPT and SIM?

4)  Is there a commercially available XPT for System VR3?  Or is there
    documentation other than the specification (something with examples)?

Thank you to anyone who responds to these questions.  Plaese e-mail any
responses to me.  Once again Thanks...
