[ovirt-users] bond or different networks for frontend and backend

Hello, here in the description (https://www.ovirt.org/documentation/gluster-hyperconverged/chap-Single_no...) it says that we should have at least 2 interfaces to separate frontend and backend traffic. How is this when I have 4 nics and I make with all one bond interface, is this not better in terms of performance? What is your recommendation with 4 x 1Gbit nics? Best regards Jonathan
