Your 1" long connector sounds like a fibre channel (FC-AL) interface. 
That's a serial interface with power on the same connector.  What the 
Origin and Onyx2 use is an SCA connector.  You can use any SCA drive in 
an Origin; for a short while I had a couple of small capacity drives 
borrowed from Sun systems in mine, wedged in place with small rubber 
window wedges, until I got enough sleds and some larger drives.

I think some SGI FC-AL disk shelf used the same sleds as the Origin. 
Perhaps that's where yours came from.
