Is it possible to combine two different SAN storage devices into a single drive in Windows Server?

Hello All,

I’m a SQL DBA and my SAN admin said that they have to migrate few drives from 3PAR 7400 to EMC CX4. So SAN team wants to have a downtime on sql servers to migrate the drives. What was am thinks was, is their any possibility to migrate the EMC Storage without bringing down the sql? i.e I have D drive with 100GB of 3PAR is it possible to add EMC CX4 (100GB) to D drive and make it 200GB. later remove 100GB of 3PAR from D drive. Please let me know is this possible?

Regards
