RAID disk controllers

Is there a RAID controller that supports Nuetrino. We need SCSI and
IDE support.

This is not a usable solution. The cost and complexity are both too
high. We need simple, under $400 IDE solution, and a simple, in the
box SCSI, maybe caching, RAID 1 and 5 support with hot reconstruct and
reporting utility from within the operating system. We have used QNX
4.23 with such a solution but, our new products need that support for
Nuetrino.

Hi Oswaldo,

The chances are if the controller worked for 4.23 then it will work for
Neutrino. Have you checked the supported chipsets yet?

Yes, I have. The controller drivers were supplied by the manufacturer
of the Adapters. PCI2000 has worked well for us for years and I want
to use the PCI2240I as well.

QNX4 did not support any RAID controllers directly. All solutions were
from 3rd parties and they can’t port it to Neutrino yet, since
‘interface is still in flux’.

What is interesting though, I could swear I saw ‘DPT’ SCSI RAID
controllers listed as supported on the http:/www.qnx.com/amiga page back
in the old days when QNX were all excited about future partnership with
Amiga :wink:

What happened to those? Unless I’m mistaken, those ‘DPT’ actually had
BusLogic chipset, which is not listed on the supported hardware page
although driver for it (devb-btmm) was in all versions since when I
remember (and I remember over 2 years back).

What a coincidence :slight_smile:

Its only IDE but its works fine for my QNX 4.25 system for several years.
I’m not sure
about your ‘hot’ rebuild under the OS but give them a ring and maybe they
can NDA the
DOS code to you…

There is no status monitoring and no hot reconstruct. It is not
reliable and is a poor solution.

Why is the ARCO unit not reliable? What problems have you experienced?

There is no status monitoring and no hot reconstruct. It is not
reliable and is a poor solution.

We have done extensive testing and found the following:

  • Failover operations were not consistant. In fact, some failures
    caused the card to lock up.
  • When technicians were working on a system and switched the disks,
    the wrong disk booted up.
  • The system did not always boot off of the surviving disk, but the
    failed disk instead.
  • A RAID 1 pair could not be cloned and moved to a different system
    for manufacturing.
  • There is no reporting and monitoring utility for QNX operating
    systems.

If I pull out my testing reports, I can list more problems we found.
This is what I can remember.

WOW. If I ran into those problems I wouldn’t use it either. I ran several
tests using their
DOS boot disk and unplugging HDs while running and didn’t have any problems.
It looks
like you ran it thru its paces more then I did…:slight_smile:

I am using the Dupli-Disk-I but they are up to Dupli-Disk-II now. Still not
enough features
(like the hot-build) to help you out though…

Sorry…

Interesting. Was that the Dupli-Disk I or II? We have been using the II
version for about a month or so with no problems and are preparing to
purchase more. The cloning isn’t an issue with us and the reporting and
monitoring can be done through a serial connection on the back of the board.
The disk swapping bit shouldn’t be a problem as in our isolated situation
and quantities this should hopefully be a very rare event – I can recall
only one actual disk failure in the last three years.

I am concerned about the failures that caused lockups. How did you test for
failover?

There is no status monitoring and no hot reconstruct. It is not
reliable and is a poor solution.

The failover testing was done with a wide variety of drives using the
Novell standard of testing which is to pull the 12volts to the drive
(motor failure). Also bit short and open testing and total power loss
of the drive was used. We also did testing with drives that had
damaged tracks (scars). IDE drives are not as well behaved as SCSI so
the controller has to be smart enough to deal with failures better.

Thanks. Good info. Don’t have much to offer you as far as NTO. Have used
DPT and PSI (www.psidisk.com) cards under QNX2/4 with mixed results. Also
Diskshadow - a software based mirroring solution. Might be able to rattle
their cages and get them to create an NTO version.

I have the PSI controller and it works well with QNX4. The company
told me that there is nothing for NTO becuase QNX isn’t releasing
anything for them to work with.
