Has anyone played with the LVD SCSI to IDE bridges that Acard is selling
now? I'm trying to figure out if they'll sync down to the speed of the SCSI
bus that they're plugged into. I'm thinking about getting a SCSI-to-IDE
bridge for my VMS system which currently uses UW-SCSI. If it will work, I'd
just as soon buy a LVD bridge, as they're cheaper and will be better when I
finally upgrade my VMS system.
I'm tending to suspect they don't sync down, as they sell U-SCSI, UW-SCSI
and U160 LVD SCSI models.

I have a UW-SCSI model, and it works on a U-SCSI bus.
The U-SCSI and UW-SCSI models have different firmware. U-SCSI firmware
has a lot more tweaks to support CD/DVD type devices, while the UW-SCSI
model is meant for harddrives, and they don't seem to care if CD/DVD
type devices don't work properly on that model.
The U160 device is a newer more expensive device. I guess maybe they
keep the UW around for people to have a cheaper option.
My Acard is just sitting in the parts bin since it wouldn't make CD-RWs
play nicely on my Octane. I intend to sometime try a DVD burner on my
U30 with this unit, but the confirmed reports of people using DVD
burners on acards on solars always involved either the U model or the
U160 model, and as I said, the firmwares are different.
Sigh.

Interesting, I can get the LVD model for somewhere around $20-30 cheaper than
the UW-SCSI model. OTOH, it's still more than I want to spend to see if it
will work or not since I don't have any U160 controllers.
I don't care if it's HD only, as I want to use to hook a couple nice big
HD's up to my OpenVMS box. What can I say, I'm looking for quieter storage.

Depends what you call big. I've got a few Quantum Atlas V 18Gb SCA-
interface SCSI drives and they're easily the quietest hard disks I've
ever come across (IDE or SCSI).

I'm currently running 6 18GB SCA Drives in a pair of Andataco 3-drive
enclosures. The drives are a mixture of Seagate, Hitachi, and
Quantum drives. Realistically, they're not as loud as the Sun
SparcServer 5/110 and it's HD that are sitting below it. I really
need to move that system to quieter HW.
For those wondering why I care about the noise level, the only place
I have to put the HW is in the corner of our dining room.

I think there is a fair chance that the company would be willing to work
with you if there are issues. So far I know of people using various
cards from Acard on Macs, Suns, and SGIs without a single glitch for
harddrives.
If you don't want to spend a lot of money, just wait for one of the
cards to be on ebay. Not always cheap, but my UW-SCSI Acard was $25.
At the moment there is one 7720UW from a seller named 55trucker that
looks like it might possibly go for a similar price.
BTW, sorry to be so long in replying. classiccmp goes to a seperate
folder and I don't get around to reading it all that frequently.
