Re: 6618 drives for model 270

[Larry Bolhuis <lbolhuis@xxxxxxxxxx>]

From a power and cooling perspective this should work fine. I probably 
would put 'blanks' in the open slots so the air going through passes 
across the drives rather than down the empty holes though.  I have never 
seen a Seagate 15K drive come for a System i. Every one has been the IBM 
variety.

The biggest feat is that the BCC drives must not identify themselves as 
any 15K drive or the 270 will reject them. If they report as FC #4318s 
then they will work and the power draw should be OK.
