Depending on what OS you intend to use, you'll want which cards you get. I know most of the ones we
used at work
wouldn't work on newer than Solaris 2.6.

Not usually; whenever I've seen it mentioned by acronym it's always
been HVD (probably my contrast to LVD, low-voltage differential).
Remember, these acronyms are adjectives, not nouns.
Sorry to be a nit-picker. And how exactly does one
pick a nit?
If you mean metaphorically, just the way you did, or the way I do in
observing that your "isnt" should be "Isn't". :-)
If you mean literally, well, go find someone with lice (head lice are
probably easier to do this with) and start searching for their eggs.
That's the original meaning of "nit" that gave rise to "nit-pick"
and
related terms. (There are much better ways to eliminiate lice than
manual nit picking. Trust me.)

You've got me confused, where do either I or the original poster say HDV?
HVD is High Voltage Differential SCSI, an "archaic" form of SCSI that
allows for greater cable lengths than standard SCSI. I just retired
a system where the HVD Jukebox sat about 50 feet away from the Sun
Ultra 2's it was connected to.

Probably a lot like one picks OTHER things...
(or, should that be "like one picks things other"?)

description of the high/low distinction in the SCSI standarad).
Cris M's supposition of "High Differential Voltage" is reasonable and
valid,
both grammatically and technically, even though it may be incorrect
as far as standard SCSI terminology goes.

I'm not sure there even *is* a formal "High Voltage Differential"

I don't have the actual *thresholds* handy for LVD and "HVD",
but HVD has a greater common mode range than LVD. I believe
if you asked 100 people "skilled in the art" what "HVD"
meant, they wouldn't think about the voltage *difference*
but, rather, the higher supply rails used in EIA485 based SCSI
(maybe HVD should be called SCSI485?? :> )

No. It's HVD, High-Voltage Differential.
And, "stuff" ISN'T spelled "stuph"!

Nits are lice eggs. A very fine tooth comb will do (looks like, but is
much finer tooth than the tool that intel gives away to remove
processors). When dogs start rapidly, even frantically, diting at a spot
of their fur, they may be nit-picking fleas.
If that isn't more than you wanted to know about it, . . .

actually, most flea and nit combs look exactly like the comb like tool
that Intel provides for removing Pentium. But the Intel pins are larger
than a normal flea or nit. I showed one to a dog groomer; she said that
it was "exactly the same, but this 'Intel' outfit must be dealing with
a lot of BIG bugs."
