Mix luns from 300 and 146gb drives when provisioning storage capacity

Ldavis100 — Mon, 16 May 2011 13:15:49 +0000

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?

EMC Symetrix DMX- Power Query

I have a EMC Symetrix DMX, which requires three phase power. Unfortunately our site only has single phase power. Is it possible to bypass the three phase PDU and connect directly to the 10A connections on the power strips at the back of the boxes. Will this work?
