Server 2012 install and RAID array

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.

Thanks,
cja

The RAID array will stay intact. Older PERCs held the config in non-volatile memory on the controller itself so it was OS agnostic. Newer controllers actually write the config on a protected reserved area of each disk so you can pull the disks, add them to a mew controller, and the new controller can recognize the array immediately.

Either way the result is that the array is intact despite what OS is installed, and even when no OS is installed. But things do go sideways sometimes so a backup is still strongly encouraged.

The data should stay intact (have a backup) but that also means ACLs. So unless this is domain joined, you'll likely face a lot of permissions issues on the data. You'll be resetting, taking ownership, and creating new ACLs on the data after the install.

Will the RAID arrays stay intact or will I have to reset all that in the perc controller set up?
