[CentOS] Is there any benefit to using NetworkManager on a server with a static IP?

I don't.  I do some fairly complex bonding, and do not use NetworkManager 
at all.  Make sure you have NM_CONTROLLED=no and HWADDR=<MAC address> in 
your interface config files.  I don't even have NetworkManager installed 
on my servers at all.
