Hi,
I'm trying to add a second drive to the new to me SuperMicro server I
just purchased off ebay. It has an Adaptec AIC-7899 U160 controller(dmesg below) but I'm finding a lot more U320 drives for sale than I amU160s.
Will a U320 drive fall back to the U160 bandwidth? I'm findingconflicting advice on google, some say no problem, other say I'll killthe U320 in short order, not seeing any hints in the man pages.
Thanks,

Jeff Ross
To the best of my knowledge U320 drives should work fine negotiated
down to U160. Or not work at all because they can't do non-PPR
negotiation.

I see.  I just ordered a drive so I'll get to test it out first hand.

I'll report back with success/failure for the archives...
