We need to add capacity to our EMC DMX4 which currently has 146 and 300gb 15k drives. The 146gb drives may be difficult to get so my questions is given todays technology with drive IOPS, should it be a concern if I need to expand the amount of disk to an existing host that currently has 146gb drives with luns from some 300gb drives? Should mixing luns assigned to a host from diffenernt drive geometries be a problem for relatively high IO applications of mixed random reads and writes?
