Pretty easy now to offer quick expansions  of existing virtual volumes on the vplex.  I didn't offer that to my vmax or dmx customers.  Wondering what others are doing out there? Concatenated expansions make me nervous even with vplex in the mix if it's a true concatenation.  Thoughts? 

We are a couple months away from metro replication.   If replication is performed at extent level and capacity add is at the virtual volume level, what steps are taken at the DR side?
