that model is not generally recommended anymore, at least not putting /usr on its own partition, there's just too many issues with that nowdays. I don't like putting /var in its own partition either as its all too intertwined with root. the problem with lots of little partitions is your freespace gets fragmented.
/home in a dedicated partition, sure. /var/lib/${DATABASE_OR_WEB_SERVER}, ditto...
The real issue is that you cannot put /usr on a dedicated partition anymore as of CentOS 7. This is because /bin, /lib and /lib64 are symbolic linked in the /usr equivalents now. The (previous) purposes of having a separate /bin and /lib was so that programs and libs required at boot time could be run before the rest of the fs was mounted up if /usr were on a separate partition. Now they've been consolidated and symlinked so if you put /usr on a separate partition then the system won't be able to access critical apps during boot.
You can thank Fedora for making that rather pointless change and breaking that capability.
