RE: I/O features not planned to be supported beyond V5R3

We're using 4326 (35GB drives) in our 810 and love it. Combined with the
2757 (I think) disk controller and its huge cache, it smokes!

Were there higher capacity drives available for the 810?  Or was the 6718 
the highest offered?  Sometimes by reducing the number of disk arms you 
can improve performance.  We went from 42 drives to 7 and had a much 
better performing machine.  Granted it was also a drop from a P30 tier 
down to a P10 tier - an 820 down to a 520.
My point being, that staying with older drives for the believe that older 
drives with more disk arms beats newer drives with less disk arms, 
performance wise:
1- may not be true
2 - may get you in a bind like you are in now.
3 - may fill up your rack space, thus limiting your potential for growth 
in the future.
