Also, separate question, why would you ever put 30 drives on a server?  I 
guess if a lot of them are slow that might work, but most servers cannot 
handle more than 2-4 LTO2 drives and definitely not more than 4 LTO3 
drives unless you have at least a DL585 + 10GBIT, even then with 4 drives 
you'll nearly max out the 10GBps card if you could push that much.
