You can simply create two virtual disks from the single RAID-5 volume.
Create one that is like 500GB for the OS volume and then create a 2nd one which uses the remainder of the space.
But pay attention to where you'd like /var, /home, /opt, etc to live. You may want to make them symlinks into directories on your larger volume if they each need space and you don't want separate filesystems, but then you have to juggle things after the install.
I've long liked having /home, at least, and maybe /opt, where some things install by default, on other partitions than root. With the larger drives we're getting these days, we've modified out kickstart for pxeboot builds to give 500G to /, and everything else as one big partition. I've also considered making that / partition smaller - maybe 250G? or less, since / doesn't really need huge tracts of land... sorry, Monty Python flash there..... In any case, doing it that way lets you do a completely clean install, if necessary or desired.
Is there a way to get /home, /var, and /opt installed as directories on that other "one big partition"? /var in particular has an odd mix of OS and 'your' data and logs that may turn out to be big. And you may not know ahead of time what to allocate for it as a separate mount point.
