the raid controller has only 2 internal channels. i thought about putting
the raid1 on the onboard controller, but i REALLY dont like that
i think ill stick with the dell way. 2x1 drives on one channel in a raid1.
8x1 drives on the other channel in a raid5. it works, its just not as fast
as i wanted.
the last thing i need to do is void the 3 year warranty we got on this bad
boy. i wonder if i put a 3rd party cage in there, dell might freek,
maybe next year when we get some bucks, we'll get a second PERC3
controller, that way we can have 4 internal channels. yee hoo!
thanks for the help though!
