What you are seeing is referring to an enclosure attached to the R720xd, with the details you provided it should be an MD1200. The update provided should be what you are needing. 
We're having issues with our EMM (part # 0W307KA00), and it shows the firmware version as 1.06. I'm trying to find the latest firmware version for it. The controller is a PERC H710p mini (embedded). Could someone point me to a page that shows where the latest firmware updates are listed? Thanks!
