Sun never do hardware raid. Their opinion is that your Ultra CPU's are
likely faster than any raid card, and better at doing RAID anyway. And any
good Sun engineer will beat your with your SS3000's backplane if he
catches you doing CPU intensive RAID like RAID 4/5.
Stick with RAID 1+0. Your only man, when you have lots of cash.
