One word of advice. Stay away from Dell kit. The PERC 4 controllers  
they use don't implement RAID 10 properly. It's RAID 1 + JBOD array.  
It also has generally dismal IOPS performance too. You might get away  
with running software RAID, either in conjunction with, or entirely  
avoiding the card.
