Going with Dell PV MD1200 and Dell PE R510 or R710 is no problem at all.
But you should be aware if you go with Dell R510 or R710 that the internal
storage PCIe slot will not work with any other HBA's than Dell H200 or H700 and
also remeber to order extra Intel nics and disable the broadcom nics in bios.
So if you plan to flash the H200 with IT firmware be ware that you have to move
the controller to another PCIe slot, but also that your support is not valid
Maybe you should keep the H200 IR firmware on the H200 controller and use
Hardware raid for the syspool and order a Dell 6Gbps SAS HBA with IT firmware.
This way you'll keep the hardware support for your Dell equipment.
