1)SCA drives use 80 pin connector that includes power, easier to pulg and
unplug.
2) SCA drives are designed to allow the scsi id to be set on the sca
backplane, just plug a new drive in and it assumes the id of the old drive.
the little 80 pin to 68 pin adapters are not very good, you can only use 2-3
separate sca adapters per channel (In my experience). An integrated sca
backplane (available from IBM or CRU (search for dataport, then look for 2, 3,
or 4 port backplane)
you may get lucky on some of the aution sites, I bought 5 18 gig sca ultra
drives for about 210 apiece. take a look ar www.onsale.com or www.ebay.com
