Hello

I've got an X6541A SCSI HVD board I'd like to use with an Ultra 10 I
salvaged from a skip. The problem is I can't seem to find any HVD
drives even in ebay. Is it possible to use an HVD to LVD converter and
if so, which one would you recommend?

Thank you in advance,

Yiannis.

Forgot to ask what host alternatives are there that work on the Ultra
10 that would allow me to use the LVD drive ? :-)

Why not just buy a LVD SCSI controller?
Certainly going to be cheaper and more compatible than trying to
change them over, worrying to make sure that you aren't frying
your LVD gear off the HVD bus. ie. I found one converter for $465.

OOTH, this is $70.

They didn't tend to make too many HVD drives. It was all for external
enclosures, and the controllers inside those enclosures, and for tape drives.

How much do you want to spend, and do you need an array?

If you got a used D1000, you would connect it to an HVD controller, and
you'd put SE/LVD disks inside. Not cheap, but nice if you need the
spindles and you've got the power. :-)

Don't forget the HVD terminator!

Yep it does make more sense to do that, however will it work with the
Ultra 10?

Very little and no I only need to play about with the Ultra 10, if
I where to set money aside I'll probably go for a Sun Blade 1000 :-)

Put the LVD drives (SCA type) in a D1000 JBOD (not as common as
the A1000 which has built in RAID hardware). While the internal bus in
the D1000 is single ended (compatable with most LVD devices), the
external SCSI connections are HVD. Depending on the version, you can
either use twelve 1" SCA drives, or eight 1.6" ones -- with the
backplane either split into two buses, or the two halves connected in
series. You'll also need a HVD terminator on the far end of the D1000's
external bus.

I'm using what used to be an A1000, but I got a replacement
logic card from an eBay auction, so it is now a D1000 in spite of its
labels.

The A1000 will also want HVD connections -- but you will need to
run special software to talk to the hardware RAID in the box.

Good Luck,
DoN.

Lovely idea, but I would like to keep this as self contained in the
box as possible, so essentialy what I am looking is
a compatible LVD controller for the Ultra 10..any suggestions?

Thank you,
Yiannis

[ ... D1000 for external HVD drive box for LVD/SE drives ... ]

If you want to keep it inside the computer, you don't *need*
LVD. Most LVD drives will happily work on Single Ended (SE) instead.
(The exception in my experience are the Exabyte LVD Mammoth-2 8mm tape
drives, which are *documented* by the maker to not be compatible with
SE.)

So -- connect to eBay and run a search for 375-0005 (A Symbios
SYM22801 card which plugs into the PCI bus, and can handle *two* SE
68-pin SCSI buses, either internal or external. The internal buses have
a choice of 68-pin or 50-pin for each, while the external connectors are
VHDCI 68-pin.

Now -- if you want to use the SCA drives (80-pin), you'll need
adaptor cards from SCA to standard 68-pin, but those are not too
expensive from places which sell SCSI stuff for the PC crowd.

And if you want to use 50-pin drives (now getting rather hard to
find) you can use the same controller -- but can handle only seven
drives (but since you want to put them internal to the Ultra-10, you are
unlikely to exceed that.)

Out of curiosity -- why do you want to hang internal SCSI drives
on an Ultra-10 anyway? I'm not sure whether it can push the PCI bus
fast enough to make full use of the drives anyway.

I've got one of those cards in an Ultra-60, and the brother card
(HVD) in a Sun Fire 280R, along with a LVD card (whose part number I
forget, and it is too new to be covered in my Field Engineer's
Handbook). The LVD card I'm using purely to talk to the Exabyte EXB-430
jukebox and two Mammoth-2 drives.

Good Luck,
DoN.
