I have a Dell R710 server running Server 2008 32 bit. I want to do a clean install of Server 2012 on it. It has 2 drives for the operating system in RAID 1 and 4 drives in RAID 5 for data. Will I lose the RAID set up during the 2012 install or does the PERC controller keep the array intact? I know I will lose the data on the operating system drives when I do the 2012 install. How about the data on the RAID 5 array will I have access to that after installing Server 2012? This will be a new install not an upgrade.
