Hello Bhushan8805, Here is a link to the latest support matrix that was released on September 18,2013. ftp://ftp.dell.com/Manuals/Common/powervault-md3200_Concept%20Guide_en-us.pdf As long as you are at the latest firmware for the controllers in the MD3200 which is 07.84.47.60 it is supported for windows 2012.  Please let us know if you have any other questions.
Folks, have anybody tested connecting MD3200 with Windows Server 2012? I have checked the supported platform matrix on dell website [ftp://ftp.dell.com/Manuals/Common/powervault-md3200_Concept%20Guide_en-us.pdf] for MD3200 in which nothing is mentioned regarding W12. Can anyone advise if they have tested and have seen any performance issues.
MD3200 with Server 2012
