Actually that's not correct.  "HD68" is the "large" connector used for Wide 
SCSI.  The SYM22801 has a pair of VHDCI connectors on the bracket for 
external devices (VHDCI is the "small" wide-scsi connector).

If you use an internal cable, you'll need something with HD68 connectors 
(which is what basically all internal SCSI cables have), and if you use an 
external cable, you'll need a cable with a VHDCI connector on it.

I recommend wikipedia... http://en.wikipedia.org/wiki/SCSI
