OK, with my new Origin 2000 machines, I was thinking that I could use
these SGI drives+sleds that I had purchased previously, where the
seller said they would work in Onyx2/Origin machines. However, while
the sleds appear compatible, the drive interface is not.
Is there any online guide that compares the different drive sled
designs for SGI machines so that I can compare what's being offered on
ebay to identify the machines that can use it?
For instance, my drives have a high density connector that is only
about 1" long, but the Origin 2000 has a high density connector that
looks to be about 2-2.5" long.
Is my only recourse to scrape through individual manuals to try and
find diagrams?

Hi Richard
The ones I have seen take standars SCA drives ????
Power and data in the same connector ??? The Connector is a little more
rugged looking. same as a Later Sun.

Looking here: <http://en.wikipedia.org/wiki/Single_Connector_Attachment>,
the connector shown in the top portion of the topmost photo,
<http://en.wikipedia.org/wiki/Image:SCSIHardDriveConnectors.jpg>,
is the one that the Origin 2000 uses.
The drives I purchased previously thinking that they would work in my
Onyx2 Reality Monster (and presumably the Origin 2000) look similar,
but not identical, to the connector depicted in the lower portion of
the photo. They must include power because there is no other
connector on the drive to supply power, but instead of the smaller
connector off to the left, it looks physically very similar to the
connector shown in the top part of the photo, only the connector has
fewer pins, is narrower and still located in the center of the sled
assembly.

The top connector in the photo is a standard 80 pin
SCA SCSI connector. The narrower one you describe
sounds like Fibre Channel (FC-AL) it's 40 pin. Both
are backplane based technologies that don't use cables
or separate power connectors.
Now, once you have drives that plug into those
connectors inside the computer, you don't necessarily
need actual sleds. A litle trick I found on SGI Octane
systems - the rails that the drive sled fits onto are
exactly the correct spacing and height to use CD jewel
cases instead. The top two bays, use regular full size
cases, the bottom one, use a slimline case. Just sit
the drive on the CD case, line it up, and mate it with
the connector. Mine has been running like this for
years. Just remember if you ever need to move it...

That sounds like FC. Can you take a pic of the business end of the
drive, or send the make/model number?
