ST318275FC drives have two independent FC-AL ports. These
ports may be connected on independent loops or on the same
loop. Port A and Port B may be connected in any order or
combination.

ST-318275FC Fibre Channel FC-AL, Dual Port (Barracuda 18 LP)
Fibre-Channel = the connector. I've never seen one myself, but I can tell you that it definately won't work with your oktagon.
I'm sorry to say this, but I think you just bought yourself a paperweight...
From seagate.com
Fibre Channel:
This refers to products with fibre channel physical and protocol layers using the SCSI command set. The Fibre Channel interface is completely different from parallel SCSI in that it is a serial interface, meaning command and data information is transmitted on one signal stream organized into packets. The fibre may be either a copper coaxial cable or a fiber optic cable. The signal on the first implementation of fibre channel uses a 1 GHz rate, thereby achieving 100 Mbytes/sec over the cable. Fibre channel also implements increased software control of configuration and pushes the total device count on the bus to 126 IDs, as opposed to only 8 or 16 on a parallel bus. For more information, see our Technology Paper on Fibre Channel. Seagate designates a fiber channel SCSI interface with an "fc" in the model number.

I've used an IBM server that was Fibre Channel based, never seen it used on anything else though!

or u can try something like this

I've got one of those... but it has a burned trace on it :-)

Yeah, well I had one of those but the wheels fell off... :lol:

You can't just adapt it. FC is a totally different protocol than SCSI.
-
You could build a RAID!
Or...........DOORSTOP!
Or flog it on ebay!
I'm not helping, am I. :-D

That WILL NOT work, besides the fact that Fibre Channel is a completely different protocol, the plugs aren't even the same. Best bet would be to relist it on eBay "AS IS".
